Accufab AFPR help

[roachjuice]

Ok I've got this universal AFPR I need to put on my car. I've got an aftermarket fuel rail for my 2 piece intake and I'm not sure which port is which. Also does anyone know what size those fittings are? And ALSO do I put this on the return side or pressure side? Thanks.

The offset port is the inlet and the center port is the return to the tank

-4AN straight cut with an o-ring. You won't find them at most hardware stores but judging from the photo you posted you already found them on our site for $6.00 for the pair.

The regulator is located on the fuel return side. It increases pressure by restricting the flow back to the tank.

Thanks guys.

Are you SURE that those ports go where you said they go?

Car tries to run on its own but it's not. I can hear the fuel pump going up and down (when it's running) like fluctuating and the fuel pressure gauge is going all over the place. It only runs if i spray some brake cleaner in the tb. Turn the key on and off 3 times to prime the system and it goes to 80+psi and that screw is all the way out on the fpr. Something's off. Any advise?

Their are three ports. Two on bottom and one in the middle on the side. The port that is shared with the gauge port (middle side) is the one that should be connected to the rail. Blow through the side gauge port and connect the rail return to the one where the air comes out. The other port goes back to the tank. The adjuster is very sensitive once you hit the "sweet spot".

So I've got it backwards. Lol. I've got the middle port going to the tank and the offset one to the rail. I'll swap em tomorrow and fire it up. Thanks Chris.

[roachjuice]

This is with the screw all the way out lol. Oops.

[roachjuice]

Just so everyone knows the middle port on the bottom connects to the rail. The offset one is to the tank.

Are those fuel fittings really -4AN? (that is 1/4"). Seems REALLY small for fuel inlet. Some of the ones I was recently looking at were -10AN inlet.

Todd,

Keep in mind that those fittings flow "unused" fuel heading back to the tank and not total fuel.

Chris-TU

[roachjuice]

Exactly. It's on the return side of the system.

Okay thanks guys for the clarification and the reply.
