$25 Fuel Pressure Gauge
#31
Its all in the install.
How did you have a needle valve setup? How open was it? It only needs to be "just" cracked.
Who said to use braided SS line? I would srap some rubber tape around the braided line, especially where it goes through the firewall. The braided line rubs up against whatever else is going through your firewall and tends to abrade whatever its rubing against fairly quick.
I use Parker Paraflex nylon tubing. Its rated at 250 psi and is good to -40. Oh, and its very quiet as well. I using an Isspro guage - not sure if that would really make a difference though.
I run braided S.S. for my oil pressure guage though.

the noise went away when i pulled the line off so i know thats the culprit, it made the rattle noise when the valve was closed and opened, so would an isolator be a wast of money, or should i just wrap this steal line with electrical tape?

i also drilled a special hole in the firewall for the fuel pressure line theres already to many damn lines running threw the stock gromit

Not electrical tape - rubber splice tape is what I used. Or you could use some type of foam or something else that will provide some cushion - but that is not going to keep it from making noise. Where/how do you have the guage mounted? That could be part of the problem as well. Maybe you could try isolating it with some rubber or something ?
I doubt the isolator will do much good - but I have not ran one myself. I have heard from a reliable source that the diesel tends to eat the diaphram in the isolator and after a short while you have diesel in the cab anyway.

You wont be seeing any more than 40 psi.
I prefer to use Swagelok (Swagelok.com the source for tube fittings, valves, and other fluid system components) type fittings, but regular compression fittings should be ok, if you know how to install them properly.
