Power driven diesel predator lift pump

But what if there was a way to improve injection system reliability and add considerable horsepower at the same time? The solution? A P-pump swap. For starters, a P-pump Bosch P adds dependability and hundreds of horsepower to the equation. Follow along as we highlight key components required in pulling off a P-pump conversion. The VP44 is equipped with a computer EDC married to the top of it, which monitors and precisely adjusts in-cylinder fueling. Fuel metering is performed independent of engine speed.

Once the factory lift pump no longer provides adequate fuel supply pressure to the VP44 and when it sees 0 psi for extended periods of timethe EDC atop the VP44 is exposed to extreme heat and eventually fails.

There is no question that the P can outperform the VP44 in every way fueling, rpm capability, reliabilityand the photo above is worth a thousand words VP44 on the left, P on the right. Even in the case of an extremely modified VP44, roughly cc's worth of fuel volume is on the table.

Larger plungers and barrels i. Dozens of different parts, quite a bit of time and a lot of work! Luckily, Scheid Diesel offers complete conversion kits to make the process as seamless as possible. Then once the valve bridges, rocker arms and push tubes have all been pulled, the lifters have to be held in place above the cam while it gets removed and reinstalled.

Because the cam has to be pulled for a P conversion, some enthusiasts use the project as the perfect opportunity to upgrade to an aftermarket unit. To further capitalize on the higher rpm capability that comes with running a P-pump, many competitors opt for a cam intended to shine at elevated engine speeds above 4, rpm. Hamilton Cams is a great source for camshafts, stronger push tubes and upgraded valve springs for the 5.

As you can imagine, trying to source all of these parts individually could take a while, which makes the all-inclusive kit offered by Scheid all the more appealing. For a street-driven P-pumped valve application such as the one shown hereeven a mildly modified P can net torwhp with the right turbo. This pump has also been treated to a fuel shut-off solenoid bolted to the rear of the pumpwhich is ideal for daily driven or street use.

The shut-off solenoid is in charge of allowing and stopping fuel flow to the P-pump i. A reworked throttle linkage is warranted in a P-pump swap as well. This version incorporates the throttle position linkage ball from the valve application into a linkage assembly originally designed for the valve engine.

It too is included in the Scheid Diesel P conversion kit. The last item of business is making sure the correct lift pump is being utilized to feed the P-pump. Unlike the VP44, which requires 8-to psi worth of fuel pressure, a P needs to see between 25 and 30 psi at all times, and even more than that if the owner is making big power. With the VP44 in the mix, the owner was having a hard time cracking the rwhp barrier — even with larger injectors and a bigger turbo feeding the engine.

Now with the same injectors and turbo, considerably more boost is on tap, traction can be unheard of at times and an estimated rwhp makes it to the ground. Of course, the truck also emits that one-of-a-kind note only a P-pumped valve can produce. Here's Where We Stand.

In many cases, the best programmer or suspension upgrade for you could be polar opposites from someone else merely because the two trucks are used differently. However, most diesel truck owners share similar basic expectations from their vehicles: dependable, powerful, and comfortable. While some may venture into less predictable classifications, those three are typically universally shared.

What this means is that one particular cold air intake is the best for the majority of Cummins owners, or that one Duramax programmer outsells the rest, and so forth.

Power to the P-Pump: Injecting New Life Into a 24-Valve Cummins

The Hyper Drive is going to have a smaller pulley so it spins the pump faster. Yeah you could add in aftermarket filtration. It would be much better for the pump and injectors with that pump. Pressures are going to change depending on the build of the truck and the components.

I would shoot Glacier Diesel a call and talk to Rich and tell him what you are doing. Idle PSI is about psi. So It will prime from the tank if you plumb it that way.

That is the way the kit is setup. I would measure your lift pump pressure and see, it may not be that at all. If it is a supply problem it will help for sure. Hi Joe The mechanical pump, driven by the crank shaft, will pull fuel from the tank, to the engine.

Once installed it may take some cranking to prime, however, after that, provided there are no air leaks, it should hold it's prime.

Add To Cart Wish List. Description Videos Blog Posts. This is a complete replacement lift pump for your factory mechanical lift pump The Titanium Signature Series diesel fuel lift pump featuring FASS' Revolutionary Whisper Technology was engineered by FASS Fuel Systems to be the top performing, longest lasting, and most reliable aftermarket filtration system in the diesel industry. By using radius cuts, tighter tolerances on all gears and a high-quality military specified coating over the aluminum base, FASS Fuel Systems was able to develop the quietest fuel air separation system on the market.

Performance Radius Cuts PRC are an advanced machining technique used to improve the flow of fuel through the diesel lift pump by creating smooth flowing cuts within the aluminum housing. This prevents the reintroduction of air and vapor back into the fuel and also to prevent stagnate fuel pockets from forming within the corner of a degree bend.The dead pedal, the long-crank hot restarts, the engine dying suddenly while driving down the road, never to restart again.

It followed a period of time where the fully-mechanical Bosch P aboard the valve 5. Needless to say, the VP44 got a bad wrap from the get-go, effectively becoming the red-headed stepchild of the injection pump world. To be sure, the VP44 remains one of the ficklest components to ever grace the legendary Cummins lineage, but there is now an unofficial protocol to follow in order to keep one alive. For more light reading on diagnosis and functionality of the VP44 from a highly reputable source, visit Blue Chip Diesel.

A cam-driven, radial piston pump, it features three internal pumping plungers, a fuel metering solenoid, a timing advance solenoid and a built-in computer called a PSG or EDC that monitors and controls fueling. The VP44 is capable of supporting bar 23, psi. During PSG failure, several different symptoms surface, with the most frequent being long cranking when attempting to restart a hot engine.

In recent years, better soldering has become part of the remanufacturing process on VP44s, which has led to improved reliability. Rotor seizure in the distributor portion of the VP44 is another issue that was especially common on early pumps due to an inferior de-burring process from the manufacturer.

In essence, the sharp edge of the rotor makes contact with the distributor, digging into both mating surfaces. After enough contact and damagethe rotor seizes up, breaking the drive plate. This sudden failure will stop your truck dead in its tracks.

A hard cold start is the biggest indicator of diaphragm failure. The revised, later model VP44s came with a solid steel backing behind the diaphragm, which eliminated the flexing that resulted in failures.

Various internal components in the VP44 tend to wear out over time, the rotor and distributor being a couple of them. When the distributor section of the pump is on its way out, hot restart issues will be present, and many times rotor and distributor failure go hand-in-hand. Being that the VP44 relies on adequate fuel supply pressure and volume in order to operate, lubricate and keep it cool, a failing lift pump can spell disaster.

A self-priming, electric Carter lift pump came standard on the 5. Bottom line: If the VP44 is not seeing at least 5 psi of fuel supply from the lift pump, it will not be happy. Did you know the hottest the VP44 gets is actually 15 to 20 minutes after the engine has been turned off?

This is due to heat soak. Nine times out of 10, having trouble restarting a warm engine means the VP44 is on its way out. The only way to ensure the VP44 stays as cool as possible is to feed it good supply pressure and volume. Whenever possible, 12 to 15 psi worth of fuel pressure should be your goal. Aftermarket electric pumps from FuelabFASS and AirDog have proven more than capable of delivering adequate pressure again, 12 to 15 psi to the VP44 on a consistent basis.

For performance applications, both companies also offer comprehensive tank-to-engine fuel systems, complete with a high-flow electric lift pump, added filtration and larger diameter fuel lines.

Just remember to run a fuel pressure gauge in case you ever have an issue with your lift pump. First and foremost, the pump is belt-driven and fully-mechanical, which means the faster you spin the engine the more fuel it pumps. Some aftermarket gauges even offer a low fuel pressure warning light that you can configure to come on at whichever pressure threshold you deem as being too low.For use with stock harmonic balancer only.

Especially if the truck has had performance modifications made, the higher demands a chip or larger injectors put on the factory fuel system can really put a hurting on the injection pump and lift pump.

The Fuel Boss kit works in conjunction with the factory lift pump to aid in maintaining optimum fuel pressure. Based off engine load and engine rpm's.

The pump is belt driven off the crank, so as demand increases, so does the supply. What Stands Out: Ease of install, how well it works and it's a simple set and forget set-up.

It was easy to see when we first opened our Fuel Boss kit that Glacier Diesel has done their homework. This kit is well thought out, and the instructions for the install couldn't have been laid out any better. This is clearly one of the nicest and best functioning fuel system kits we've ever tested at Diesel Tech.

Plus, Richard Martin, owner of Glacier Diesel, is a super nice guy and was more than happy to spend time with us on the phone, answering questions and offering more help in anyway he could. The entire install took just a few hours and required just basic hand tools. Everything we would need for the install was supplied in the kit, including a specialized tool for setting the belt tension. Your truck still uses your factory lift pump to pressurize the fuel system and start the truck, but once a certain pressure is met and the truck is running, a hobbs switch is triggered which shuts off your factory pump and sends fuel through the new belt driven pump.

At an idle our That's a major improvement over our failing stock system that would drop down to psi at wide-open throttle. The system includes a check-valve to prevent back flow, and a pressure switch that will allow excess fuel to return to the tank when the pressure in the system meets a preset level.

The harder you push the truck, the more the pump will supply. No more fuel pressure drops under load and heavy acceleration. One thing we want to point out is that this truly is a set and forget system. Once its been installed and the air is out of the system, you really forget it's under there. It's quiet too, you won't here that familiar humming noise coming from your fuel system like some of the other electric fuel pumps on the market.

The Downside: Well, nothing comes to mind really. We are percent satisfied with this system and would recommend it to anyone in the market for an aftermarket lift pump system for their Dodge Cummins. Low fuel pressure from a stock lift pump can destroy an injection pump in no time, leading to costly repairs. The factory VP pumps on the early 24V 5. Close Search. Subscribe now!
