fuel test port

95 jimmy 4.3 my fuel pressure test port is leaking at the little push valve, can i just replace that or do i need to replace the port or the whole fuel rail. thanks k

You can replace just the valve core but, the seal must be "fuel rated" and you'll most likely only find it at a GM dealer, (or a boneyard).

thanks for thereply, went and bought the port at stealership alls well, cost 43.85 but had to get it
