Do You Even Lift Pump Bro?

 

This post aims to answer three questions:

What are Lift Pumps?
Why do you need one?
Which pumps we recommend and why?

There’s a lot to unpack here, so let’s just jump right in.

What are lift pumps?

Now it doesn’t matter if you own a Powerstroke, Cummins, or Duramax diesel truck, a lift pump is going to do the same thing for each engine. Essentially, what a lift pump is, is a low-pressure pump that supplies fuel to a high-pressure pump. Maintaining that constant high pressure is key to overall engine performance and health. The normal range for these injection pumps is between 15,000 & 30,000 PSI, depending on what type of injection pump you have. Newer, electronically controlled trucks hit that 30,000+ PSI range (Siemens, CP4, or CP3). That pressure is fed to the common fuel rail and then the injectors handle business from there. Nonetheless, in either variety of pump, if your pressure drops, you lose power and risk damage to the engine itself. Low pressure is no bueno and can cause the injection pump to fail.

When do you need a Lift Pump?

If you’re like us, you constantly want to get as much power out of your rig as is humanly possible. This puts some stress on the stock engine filters, lines, etc. The newer trucks (2007+) have a higher tolerance than the older ones. The point of “too much pressure” comes earlier in older diesel rigs.  This when you should be adding a complete fuel system like those from FASS.  They offer a full on, complete system addressing all the main concerns at once. With a system like those from FASS, you get a filter, pump, AND lines. This gets rid of the bottleneck and lets you add as much horsepower as you can.

What Lift Pumps do you recommend and Why?

To be honest, most all Diesel Lift Pumps are pretty damn good. Here at Husker Diesel, we use FASS Lift Pumps. It’s not just the quality of the product, it’s the service and backing the company provides. We believe wholeheartedly, that when a company stands behind their products, their products tend to be on the higher quality side of things. Other brands such AirDog & Fuelab have decent choices too. However, we stick with what works the most consistently.

Other things to note

Upgrading lift pumps is a simple process. The biggest question when choosing a lift pump is most definitely whether to go with a 100-150GPH or something bigger?  Typically if you are going to do the standard diesel mods (tuner, cold air intake, exhaust, injectors, or new turbo) you can live with a less than 150GPH Lift Pump. If you are getting into the 1,000HP+ and bigger injectors, higher-pressure pumps, or something like a pulling truck (high RPM), then we definitely recommend getting something in the 150GPH and up arena.

You will hear a lot about water separation and better pressure from all the Lift Pump manufacturers. Which is a good thing, don’t get me wrong. However not talked about much is the immediate increase in horsepower. We can see usually 10, 20, and even 35 HP increase across the board from just adding a more PSI to your fuel pressure.  It varies per everyone’s specific application so that is why it’s not advertised much.

Whatever decision you go with it is highly recommended you do your research before getting a Lift Pump for your truck. We strive to offer top notch support for our customers, you might have heard that about us.  Check out our selection or Give us a call if you have any questions! 402-502-6961 M-F 8AM-5PM CST.
