Key Features & Benefits

• True in-tank design – Direct replacement for the factory pump module. Retains stock fuel lines for a cleaner, faster install (no external pump, no cutting, no extra plumbing).
• Active fill bucket – Eliminates the common ¼-tank fuel starvation issue, tank sumps, and draw straws that plague many high-flow lift pumps.
• New sending unit & float – Includes updated electronics and fuel level sender so your gauge works correctly again.
• Aftermarket-ready – Outlet and return are threaded for -8 O-ring (3/4"-16) fittings if you want to run aftermarket filters or custom lines.
• Proven performance – Steady 6-8 psi operating pressure at idle with increased flow capacity to support modified engines.
• Biodiesel compatible – Validated for use with up to B20 biodiesel.
• Limited lifetime warranty from Fleece Performance.
