I ordered cheapest FPR I could find on Amazon just for the gasket, unfortunately one piece.

 

I had an Aeromotive FPR fail on me and almost wipe out a engine. Never again, I would look into Kirban.

Thanks for the heads up! Do you recall what type of gasket you used?

BKO is running extremely Lean, if I got on it, even in slow speeds it would buckle and struggle. With new FPR, around town is normal, only struggles with highway driving now. I have it set at 60psi, but still loses all pressure when engine is not running (Ignition On).

 

I had to get one from the hardware store I cant remember the o ring size.

60 seems high.

 

Agree with @Gregor , 60 seems real high. I have a tune in my Bronco and the pressure is still only set at 50.
I'm surprised you were able to get fuel resistant o-rings at a hardware store.

FWIW, the aeromotive FPR on my rig has been relatively trouble free.

 

If you are pushing that much pressure and you are not pig rich something else it wrong. Bad injectors or ECM.

 

I need to start a new thread after I get to the bottom of this FPR issue but this is not a stock engine, in all honestly I don't know what the correct Fuel Pressure is, but stock is to low. I cannot get anyone to tune this engine in my area.

Back to FPR, below video (16:10 mark)shows what I was referring to in regards to gasket. Every FPR I found has the one piece gasket that goes around both tubes, tried to use but it is leaking (obviously) and O-ring was leaking as well. I am going to hit a Speed Shop near me tomorrow and see if the have these flattened O-rings.
