Well searched much through google and here and didn't get anything , I have Fuel pressure gauge installed since one month it was running good after that i drove the car and when i run the car it shows the gauge reading 18psi all the time and won't change , I checked the wiring and everything wired right , Tested the fuel pressure through stand alone gauge and it was reading 55-60psi at idle, Can you please tell me what's wrong with that ?

I had the same problem with my digital Cyberdyne guage and it was the sending unit. It had teflon tape around the threads and these units use metal to metal ground requiring no teflon tape or paste. Bought a new sending unit installed without any tape and works great.

Yeah I installed it with a tape around the sending unit , But if installed without tape , It won't leak ?

Sounds like a bad sending unit.

The threaded part isn shaped with a slight taper to prevent leaking. Go online and look up the install instuctions for your unit to be certain.
