Diesel engines are already powerful and fuel efficient on their own, but there are a few things you could do to make the most out of your engine (in particular, using the lift pump). After all, even with the largest tank and the most powerful engine, an improperly fitted lift pump might just mean that you are not making the most out of your fuel, or that you may even be underfueling your engine.

The benefits of lift pumps

While the power output of the engine is dependent on a lot of factors, you could increase this by hooking up your lift pump to your factory suction and feed lines. Your limiting factor here will be the flow rating of the lift pump you chose. However, extra precautions might be taken, especially if you use an aftermarket lift pump to increase your power level and fuel delivery volume.

Lift pumps are an essential part of truck customization, especially if the goal is power. They are not as visually-pleasing as a supercharger, but are no less essential. In addition to raising fuel volume, they also improve filtration, allowing better quality fuel to run through the system. 

How they work 

A lift pump supplies low pressure fuel from the tank to the injection pump on the engine, providing roughly 8–15 psi of pressure supply. The injection pump or injectors then pressurizes the fuel into the cylinder at somewhere between 15,000–30,000 psi. 

The lift pump reduces the effort that has to be made to pull the fuel all the way from the fuel tank. Having a lift pump can extend the lifespan of your engine, especially since it reduces the stress on the injection pump or injectors. It does this by preventing fuel starvation, which is incredibly damaging to the entire system.

When would I need one

In any instance where you hope to push your vehicle beyond the stock limits of its power, a lift pump is advised. After all, the injection pump and injectors are the most important components of a diesel engine. With a lift pump, you can supply your engine with bubble-free and purer fuel. 

Such needs arise if you like to customize your vehicle, or if you would like to raise your truck’s suspension. Raising it puts strain on an engine that could definitely be alleviated by a lift pump. 

What would I need to watch for

If you are investing in a lift pump, invest in a gauge as well to make sure it is operating at optimal conditions. Make sure to note for fuel pressure drops, under-acceleration, or wild up-and-down pressure swings. These are signs that there might be a problem with your lift pump system,

In conclusion

Lift pumps are fully optional, as most trucks are designed to a specific level of power output already. But for the more discerning needs and preferences, a lift pump could extend the lifespan of your diesel engine and also your car. This is especially necessary if you plan to use your truck in rough terrain.
