FASS Fuel Systems

FASS Diesel Fuel Systems

Titanium Signature Series Fuel Air Separation Systems providing 2-micron filtration, air removal, and continuous positive fuel pressure to safeguard high-pressure injection pumps.

Protecting Your Diesel Injectors from Cavitation & Moisture

Modern common-rail diesels (such as Bosch CP4 and CP3 pumps) operate at pressures up to 30,000 PSI. Entrained air and tiny moisture droplets in cold diesel cause microscopic pitting, injector sticking, and catastrophic pump failure. FASS removes air, vapor, and moisture before fuel ever reaches your high-pressure pump.

✓ Eliminates air and vapor bubbles for consistent spray pattern and smoother idle
✓ 2-Micron debris filtration & 99% water separation efficiency
✓ Whispa Technology for exceptionally quiet pump operation in cold weather
✓ Protects expensive CP4 pumps from fuel starvation and metal contamination
