FASS Fuel Spring

The FASS Fuel Spring line offers replacement base springs for FASS diesel fuel system components. Depending on the variant, these springs work as a fuel pressure regulator spring or a fuel pump spring. They are made to help the fuel system hold steady, consistent pressure.

Key Features:

• Replacement base springs designed for FASS fuel system components
• Help maintain stable, consistent fuel pressure
• Compact design that is simple to install
• Made from quality materials, with steel construction on regulator springs
• Backed by FASS Fuel Systems, a name known in diesel fuel delivery

A worn or wrong spring can change fuel pressure. Replacing it with a genuine FASS spring helps restore the pressure the system was designed to deliver. Each variant has its own pressure rating and intended component, so choose the one that matches the part you are servicing.
