Tired of fuel pressure guage!!!

I have a dipricol fuel pressure guage that I have changed around from running 1)fuel line straight to guage 2)running a needle valve and fuel line straight to guage 3)running dipricol's isolator. No matter how I run it I get to listen to the engine resonating thru the guage
So I'm going to run a dipricol pyro in it's place If anyone has a used pyro pm me.

Sounds like you have the needle valve open too much. I run all of mine barely 1/8th turn open from fully closed.

Try an electric gauge. I get no noise from my Autometer NV's.

I have a dipricol fp gauge and it's quite as can be. In fact, I never knew something like you have could even happen.

I want to add a dipricol EGT gauge to match, but they're like $190!

nothing but problems with my autometer electric fuel pressure gauge-the sender has been replaced twice, the gauge once- now when i aplly the brakes the needle reads higher-then goes back down to the correct reading- autometer wants me to rip out the gauge, for thre third time!! i had to do it twice before before they said it was bad senders!

need rubber fuel line ( I used Gas fuel injected rated hose, 60psi? ) )
from pressure tap to firewall, with a little slack..
than 1/8 copper line through rubber groumennt at firewall to gage..
don't need a snubber. but can leave in the rubber hose...

My 2002 std shift was LOUD with the steel braid fuel line ,
Above worked. NO noise

I have had to replace the pyro gauge once and the temp gauge was DOA. I bought the gauges from egauges.com: best customer service i have had in a LONG time. egauges swapped out both, no questions asked!

My Autometer electric fuel pressure gauge has been installed around 2 years now without any issues. My sending unit is T'd into the fuel line running from the FASS directly to the CP3, no need for snubber. It is located about where the fuel line goes under the firewall. This is easiest place to run guage wiring from into cab. Sounds like you have had bad luck with gauge reliability for sure.
