Why Your Diesel Engine Could Benefit From an Aftermarket Lift Pump

When it comes to your diesel application or any application for that matter, eventually stock just doesn’t cut it. Factory parts and mechanics can serve you well for many years but ultimately there is a need to upgrade the performance of your diesel engine. Upgrades can get tricky and most of them are contingent on completing prep-steps before any part swapping can be completed.

One of the parts that end up being replaced with a higher performing model is the diesel fuel lift pump.

What is a lift pump?

Basically, it’s a fuel supply pump that takes fuel from the tank and transfers it to the injection system. Typically, most diesel engines are equipped with some sort of fuel pump whether it’s a mechanical injection system found in older models or the new models where the pump is integrated into the engine itself.

Why would you need a new one?

Upgrading engines with aftermarket and performance parts isn’t a new concept and frankly transcends even the diesel world. Just about anyone and everyone wants to upgrade something about their engine, whether gas, diesel, or vegetable oil (not sure how many upgrades are available for a deep fryer, though). Despite the fact that a diesel engine holds the top spot for the most efficient internal combustion over all other engine types, adding a new pump to your diesel engine can vastly increase its performance well past the factory limits.

How would you go about it?

The goal of the modification is to increase the amount of fuel that’s being injected into the engine. You would need to start this process by increasing fuel flow with computer programming (newer models) or by installing high-flow injectors. With the engine demanding more fuel, you’ll inevitably need to upgrade your pump. Bad fuel pressure means less horsepower and, in some cases, damage to the injection pump.

When deciding which lift diesel lift pump to purchase, it’s important to remember that first word: diesel. There are gasoline pumps that can be retrofitted for a diesel application but will ultimately fail, sometimes immediately. Consider opting for a pump and filter combination which offer performance as well as better and higher capacity filtration.
