FiTech 35661 Details

The FiTech Force Fuel Mini is a compact, high-performance inline fuel delivery system designed specifically for EFI conversions in street rods, hot rods, and tight engine compartments. It uses a low-pressure feed from your existing mechanical or electric pump to fill its internal reservoir, where a built-in 255 LPH high-pressure pump and integrated regulator maintain a steady 58 PSIeliminating the need for major fuel system modifications or return line rerouting in many setups. The mini reservoir's small footprint fits easily under hoods with limited space, and the versatile mounting bracket allows installation in four different orientations for maximum flexibility. Included high-pressure fuel hose, AN fittings, liquid-filled pressure gauge, 10-micron filter, and return line bung make it a complete, bolt-on solution for reliable, consistent EFI fuel supply up to 600 horsepower.
