I was kinda wanting to mount a gauge on the fuel rail since I broke my schraeder valve clean off today. If you have a rail mounted gauge let's see pics because I don't know how visible it will be at the back of the intake manifold.

Also if you have a fuel rail for 94-97 sitting around please let me know!

 

I think there is some concern over the weight of a gauge hanging on that already as you found out flimsy piece.

 

That may be why mine broke. Had a safety switch on there.

 

Think about that little bit of weight and the leverage it provides and then every shake and shimmy of the engine.

 

I would have a stronger fitting TIG'd onto the side of the rail.

 

If I do that wouldn't I need a new set of lines too?

 

You can do it. But you need to do it properly. You have to drill and tap the flat portion of the rail. I have had a psi sensor in mine for 10 years.
