Stock 87 GT 2.8

If I wanted to add a permanent fuel pressure cause in place of the Schrader valve on my rail, what parts would this take. I was just thinking of threading it on with a 90° elbow and Rossi. the gauge on there turned where it readable. I see fiero store sells them, but 80$ seems steep for just a couple fittings and a gauge. Thanks.

If you want a fuel pressure gauge you're gonna have to spend some money. This is the one I have on my car, but it is $72 and Summit will charge $10-15 for shipping.

I can get a pressure gauge from work for free. Its the fittings I'm concerned about. Like what size thread the Schrader is. I could even do this in copper with flared connections if need be. Just not sure how well copper holds up to fuel. Or stainless tubing, I have tubing benders and a flaring tool. Just wondering on sizing everything.

I believe it's a -4 AN fitting. It's different threads and contact angles than flared copper fittings. I used a 90* swivel attached to a female 90*. I have seen others use a straight connection to get the gauge above the intake.

Copper is fine with fuel, but copper tubing work hardenes with flexing and vibration, so stay with steel if you have to use some tubing. Just go with the AN adapters and screw in a pressure gauge. Larry

You may want to consider this. Holley adjustable pressure regulator along with a mechanical gauge. This pic borrowed.


I went this method but used a sensor in the schrader port for an electric gauge mounted remotely where I could see it. The Holley regulator made it adjustable.
