Our FASS Fuel Systems Signature Series Adjustable Diesel Fuel Systems stand out as the most versatile and high-performance fuel system on the market, specially designed to meet the demands of high-performance Ford Powerstroke 6.7L applications. Utilizing the same motor as our Titanium Series Systems, this adjustable fuel system is rated at 140 gallons of diesel fuel per hour and provides adjustable fuel pressure ranging from 1-75 PSI. This customization capability allows for tailoring fuel delivery to the specific needs of race or competition diesel engines. To enhance overall performance, we have incorporated a boost compensation port that adjusts fuel pressures based on air pressure from your intake manifold, ensuring consistent fuel pressure under full throttle conditions when it matters the most.
Powerstroke Adjustable High-Performance System Features:
