This mechanical fuel pump is designed to work with stock or mildly modified engines and delivers a free-flow output of 80 to 130 GPH. The body castings can be rotated 360-degrees to ease mounting in difficult places. It is not compatible with methanol or alcohol fuels and should not be used with fuel injection systems. The heavy duty construction can withstand long periods at high RPM and it uses 3/8" pipe thread inlet and outlet ports.
