What does a Cummins lift pump do?

The purpose of a lift pump is quite simple: to provide fuel to the injection pump. The fuel doesn’t need to be under high pressure (that’s the job of the injection pump), but it does need to support the volume demands of the injection pump, which relies on diesel fuel for lubrication.

Do lift pumps add horsepower?

For diesels, lift pumps are the unsung heroes of their respective performance world. In addition to making big horsepower a reality, they add reliability to the entire fuel system, yield improved filtration over stock and (if electric) offer infinite adjustability over fuel pressure.

What is the difference between a fuel pump and a lift pump?

Modern fuel pumps allow automobiles to operate at higher speeds and improve fuel economy in cooperation with a fuel injection system. Lift pumps add to that system by helping raise the level of fuel into the engine block by creating suction and managing air flow.

Is a FASS fuel system worth it?

But it’s well worth it. The pump doesn’t have to pull from out of the top of the tank. If you want to upgrade your your truck it’s an awesome place to start. I would recommend Fass to everyone.

Can a lift pump be too big?

No it will not hurt the pump. But it could cause you headaches down the road. Running way too much fuel to an injection pump that can’t handle it can cause an increase in fuel pressure, which on some trucks could cause damage to that injection pump and possibly cause it to fail.

    Do all diesel engines have a lift pump?

    Virtually every diesel has a lift pump of some sort, from the old mechanical injection systems, to Ford’s HEUI system, to newer common-rail rigs. Even engines like GM’s Duramax actually use a factory lift pump built inside the engine’s high-pressure CP3 pump to draw fuel from the tank.

    How does a lift pump work?

    The task of the lift pump is to pump fuel. This lift pump is situated where the fuel tank of your vehicle is. By using a vacuum or a DC motor, the lift pump pulls fuel oils from the oil tank, pumps it with high pressure, and sends it to the injector lines to create a spark and, consequently, a burning to run the engine.
