Default Testing fuel prssure

My 1984 Corvette has the Xram intake modification. The fuel lines were somewhat modified from the stock crossfire and the last owner left off the schrader valve off. Is there any other way to test the fuel pressure or is there some sort of kit where I can make new lines with a schrader valve in it?

Could you drill and tap in the fuel rail and screw this in? Dan

I guess my ideas are dumb. Not the first time, but at least the OP could come on and say my ideas are dumb. Oh well, Dan

If you are going to do this Dan, make sure your NCM agreed value policy is in effect and has no clause against drilling into the fuel line

Pretty sure they would not write me a policy. I wonder how many people called to get a copy of the policy. Dan

Did you read it cover to cover? You have to admit it is hard to read. I would love to get a copy of a GEICO policy and compare it word for word. As was shown the NCM insurance is really GEICO. Dan

Looks like something you put in place of the fuel filter so a gauge can be hooked up. I know TBI can use an adapter that screws into the throttle bodies inlet but I'm not familiar with crossfire plumbing and the feasibility of using one.


or you can try something like this... https://m.media-amazon.com/images/I/...tB+KL._AC_.jpg
