FASS Fuel Systems
FASS builds fuel air separation systems and high-flow lift pumps that pull water, air, and vapor out of diesel fuel before it reaches the injection system.
Quality parts, installed right.
Clean, consistent fuel pressure is the single biggest favor you can do a diesel injection system, and a FASS system delivers it while pulling water and air out of the fuel. On Havasu trucks that tow and run in the heat, that protection pays for itself.
A FASS install is one of the most common upgrades we do, and we set them up right so they actually perform the way they should.
- FASS lift pump and fuel system installs
- Water and air separation for cleaner fuel
- Protects injectors and high-pressure pumps
- Sized and set up for your truck and use
Who FASS Fuel Systems is
FASS (Fuel Air Separation Systems) got its start in Missouri and built its name on one idea: diesel fuel runs cleaner and engines last longer when you remove the air, water, and particulates before the fuel ever reaches the pump and injectors. Their Titanium Signature Series and adjustable lift pumps have become a default upgrade for owners who tow heavy or rack up the miles.
We are not an authorized FASS Fuel Systems dealer, we are a diesel shop that chooses to run FASS Fuel Systems because it holds up. We help you pick the right setup for how you actually use your truck, install it correctly, and stand behind the work.
