Fuel Pressure

I did the mods all at once and the fpr is probably 6 yrs old. I didn't have money for a fpr at the time so my friend gave it to me.

When I first started my car the fpr leaked a little. I didn't notice it until the car was already running for a while. I saw gas puddled on the intake. I started it again and it wasn't leaking. I kept checking it periodically.

I do hear a hissing sound by the fpr when the engine is running. My car also runs lean and only gets cured when I crank the fuel pressure up to 50psi at idle. I didn't drive the car much because I knew something was wrong.

Thanks guys, I will try what you have suggested.
