FiTech 36371 Details

The FiTech Go Fuel In-Tank Returnless Fuel Pump Module with 2-Inch Fill (single pump model) upgrades fuel cells or custom tanks with a reliable internal electric fuel pump system supporting up to 800 horsepower. This returnless design uses a single efficient 340 LPH pump paired with an integrated regulator maintaining 58 PSI, eliminating the need for return lines. The CNC-machined billet aluminum top features a 12-bolt flange for secure fitment in most fuel cells or custom tanks, plus an integrated 2-inch filler neck with sealed cap (extensions available separately). Adjustable pump positioning for 7-16 inch depths, effective debris filter, nylon hose, Viton seals for E85 compatibility, -6AN ORB feed/return outlets (fittings included), and secure wiring terminals make it ideal for high-performance EFI or carbureted setups demanding clean, high-pressure fuel delivery.
