75psi Regulator Spring for FASS

This custom regulator spring will run a 125G FASS Titanium Series pump at 75psi. This pressure is required in Ford 7.3L and 6.0L applications, in order for the engine mounted fuel pressure regulator to be able to properly manage the overall fuel system pressure.

IMPORTANT NOTE: This regulator spring is ONLY recommended for use with FASS 125G Pumps that are configured to run at 55psi from the factory. While all other FASS 55psi pumps could use this spring for increased pressure, FASS feels that this will result in premature pump failure and will not honor the warranty!

IMPORTANT NOTE: This regulator spring is to NOT be used with the new TITANIUM SIGNATURE SERIES PUMPS! These new pumps already come with the 75 psi spring installed!
