Fuel pressure question - HELP!

[Stang_ROTY]

Damn,

That's it for all the$$ I spent?? What the hell is wrong with my setup?????

My gauge is new just like everything else...except the fuel pump and regulator which was given to me by the previous owner of the car. So what is the procedure for setting fuel pressure?? Do I unplug the vac hose going from the regulator to the manifold and set it..then plug it back in??

I need to make more HP for the dough that I spent :-( Maybe you're right and I'm running too rich....but the plugs aren't telling me that story. This is getting more frustraing than fun...

thx

I think your fuel pressure gauge might be messed up cause @43psi your car would be running pretty rich.
and @50psi it would be running way rich.

IMO its either your gauge or your Fuel pump.

As far as setting the fuel pressure you are adjusting the WOT fuel pressure. @WOT there is zero vacuum. That is why you set the fuel pressure with the vacuum hose disconnected. If you unplug the hose with the car running the fuel pressure should shoot up to where you set it at and then you when you plug the hose back in it should drop back down.
