When supply fuel pressure drops, the injection pressure into the engine will also drop, and so will horsepower. Once the engine’s fuel demand is turned up to overdrive, the factory lift pumps are always one of the first parts of the system to fall short. This can be done by programming (if the truck is computer-equipped), or by mechanical means such as higher-flowing injectors. So that begs the question, why should you buy an aftermarket lift pump if your engine already has one? Well, when it’s time to increase the power of a diesel engine past the factory settings, invariably the amount of fuel that’s injected is one of the first modifications that’s performed. Aeromotive also offers some of the highest-flowing electric pumps out there, with ratings well into the 250-gph range.

With properly sized fuel lines, we’ve seen Aeromotive’s series of lift pumps last for years in diesel applications. 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. 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.

Simply put, a lift pump is a supply pump that transfers fuel from the tank, up to the engine’s injection system.
