FASS Fuel System Installation
Performance Upgrades — Cheyenne, WY
A FASS system is a frame-mounted lift pump with serious filtration and air/water separation — and on modern common-rail diesels it's one of the best reliability investments available. It feeds the injection pump steady, clean, air-free fuel, which is precisely what factory in-tank pumps struggle to do as they age, and what CP4-equipped trucks need most.
TDC installs FASS systems with clean mounting, protected line routing, and proper wiring — plus honest sizing advice: a stock towing truck and a 700-horse build need different pumps, and bigger isn't automatically better.
What's Included
- Superior filtration and water separation
- Removes entrained air for smoother running
- Protects injectors and injection pumps — CP4 trucks especially
- Sized honestly for stock through built trucks
- Clean install: mounting, routing and wiring done right
How TDC Approaches a Build
- Start with the mission
Towing, daily driving, or fun — the truck's real job decides the parts list.
- Check the foundation
Compression, fuel system health and transmission condition get assessed before power gets added on top.
- Build as a system
Turbo, fuel, airflow, tuning and transmission have to match. Mismatched parts make heat, smoke and broken trucks.
- Support it after
The same shop that built it maintains it — no finger-pointing between the tuner and the mechanic.
