Description

Holley Street Performance mechanical fuel pumps are designed to work with stock or mildly modified engines. Ranging in performance styles of 80 to 225 gph, their body castings can be rotated 360 degrees to ease mounting in difficult places and they have large orifices for high flow rates. These pumps are not compatible with methanol or alcohol fuels and should not be used with fuel injection systems. A fuel pressure regulator is required for 130 gph versions.
