AEM afpr??'s

[000triple000]

I hooked my brand new baught form extremepsi.com AEM AFPR also with a 0-100psi gauge. Well anyways I installed it, I put a block off an fitting on the right side (looking from the front)and routed my fuel hose from the pump to the left inlet side on the afpr, and I then routed the hose from my fuel rail and hooked it up to the bottom of the afpr, I used teflon tape on all fittings just for extra security, And then my vacuum hose was hooked up and t'd to my boost gauge and then to the intake manifold. I started my car and I looked at the new gauges hoping to see something, (the afpr comes set at 40 (what the owner manual says)). When I look at the gauge (WITH MY CAR RUNNING A.K.A GETTING FUEL) it says 0 psi of fuel going through. And then I started leaking oil and coolant some how I think because underneath ym car it was a milky puddle. But car sounded fine and I did just do a rebuild, so maybe its time to retighten the head studs. (new cometic mls headgasket) Fresh build on motor (EVERYTHIGN SEALS TO INTERNALS). Does anyone know why my brand new afpr is not working???? or the gauges at least. It was all ordered form extremepsi.com

Its because you have it hooked up wrong if its installed the way explained. Now let me get this straight...

- You routed a fuel hose from the PUMP to the left side of the afpr.
- You routed a line from your fuel rail to the bottom of the afpr.
- You blocked off the left inlet on the afpr.​

Where in the hell did you get your install directions from?

nope I didn't hook it up ass backwards or anything. I have a vacuum line from afpr to the intake, 0-100psi gauges throught the 1/8 npt fitting, on one inlet side i have the hos coming from the pump. on the bottom I have the hose that goes to the fuel rail. and one inlet side blocked off. I hooked up my wideband and the car said it was running 13 steady, then when gas was applied it would lean out. My afpr is still reading 0 with the vaccum line pulled off and on. I have a picture of how I installed it.

Your picture doesn't show anything of importance other than the fact that your fuel lines and clamps are scary, you should use proper AN lines or Push-Loc lines.

They way you described it in text is that the regulator is between the fuel pump and the fuel rail and this is WRONG. The regulator goes on the return side of the rail where you should have removed the stock regulator from.

Please take a farther away picture that actually shows the fuel system.

I posted the diagram so you could fix the issue rather than disagree with me, pay attention to detail man. Look at the drawing I took the time to draw for you...

Note: The regulator goes after the rail, not before.
Follow the diagram that Corey posted in post #3.


EDIT: I'm too slow...

It goes AFTER the rail, just in case you didnt see what 99gst_racer said. not before, dont ask for help and then argue whos right with them. Your wrong, hook it up the way the Diagram shows and you will have fuel pressure.
