The How and Why of a Lift Pump System


Understanding the How and Why of a Lift Pump System

Our modern diesel pickups have changed and improved drastically in technology since they were first introduced in the 1980s.  We now have variable vane turbos, six-speed automatic transmissions, piezo injectors, and the list goes on.  However, even in these modern diesels, there are aftermarket options available to help improve the performance of these trucks.

One of the first modifications to consider on your diesel is adding some type of fuel system assistance like an Air Separator Lift Pump System.

What Does A Lift Pump Do?

Some of you might be familiar with the term lift pump because it’s a common upgrade for most diesel pickups.  A lift pump assists or pumps more fuel to your injection system which is beneficial when creating more power, but an Air Separator System does more than just that.

An Air Separator Lift Pump Fuel System is exactly how it reads; it pumps fuel at a higher volume that your factory fuel pump (if equipped), and separates air from the fuel.  Why is that important?  By getting raw fuel to your injection pump and to your injectors, you get a cleaner and more efficient injection event because you don’t have excess air bubbles in your fuel system.  By having the least amount of air running to your diesel’s injection system, you have a higher rate of fuel to the engine (if needed in a higher horsepower application), increased injection pump life (by keeping agitated fuel from running through the injection pump), and increased fuel economy (resulting from the cleaner injection event), all combining for a better driving experience and a diesel pickup that lasts longer.

Below is a video made by Pure Flow Technologies demonstrating how their Air Dog II Air Fuel Separation System operates.  Check it out:

If you are interested in an Air Dog, Fass, or Fuel Lab Air Separator System for your diesel pickup, give us a call and one of our experienced technicians can help you out.  In my opinion, this is one of the first modifications that one should consider for their diesel pickup.  It will not only save you money in fuel economy, but will save you money in the long run by keeping the injection components happy in your diesel pickup.
