i have a '91 integra LS w/ a B18A1 engine. what is the stock fuel pressure (at the fuel filter) supposed to be? i have one of those B&M fpr's and gauge, and I need to know the baseline so I can put it into the equation for some mods I am doing. thanks!

Try about 32 psi with the vacuum line disconnected.

32 psi with the vacuum line disconnected would be like 25 with the vacuum line connected. isn't that a bit low?

 

i know you're safe between 30 and 45 with stock internals with the vacuum line connected. without it, the reading would be inaccurate. it's right around 40 now, but I think it's running a little rich cuz i can smell gas fumes coming out of the exhaust and my gas mileage isn't that great.

so uh....does anyone know the number?

 

Helms says between 36 and 40 for the B1 (same as A1).
