anyone know what kind of fuel pressure (psi) numbers should be expected from a pretty stock 5th gen prelude? trying to track down a fuel line leak and i will be installing a gauge to do some monitering, but have no idea what numbers to expect for a normal car. thanks!

 

bump. anyone know???

 

does anyone on here even have a fuel pressure gauge!? or any kind of info/specs on a stock prelude's fuel pressure would be helpful.

 

47-54 psi is the normal range of pressure with stock parts.

 

Helms says 40-47 with the vac line off.

 

coo thanks. i just got the gauge in the mail today and just finished installing it. i got an initial reading of like 45-48 psi from priming the fuel system. but then after the priming stopped, the gauge slowly started dropping down. the last look i got was something like 36-38 psi. I KNEW THERE WAS A LEAK SOMEWHERE! looks like i get to track down a leak after all...

 

you sure that isnt because its equlaizing in teh system? after all once it primes it stops pumping, and the pressur regulator is NOT a closed door type setup. it is a restricted opening based on a certrain level of flow.
