i think its either a blue or a black, i recently put a rebuild kit into it with a new gasket spring and the other little black thing that goes inside of it. also a brand new holley fuel pressure regulator.
i originally was going to go this route but i couldnt find anywhere to put the regulator without moving everything around. so i decided to just get a red 7psi pump and call it a day.

asking $30 + ride if you dont pick it up. includes all fittings shown which are -8's. you'll need a small 3/8 plug on the other outlet side of the regulator.
