Re: AEM Fuel Pressure Regulator Problems (D-Man)
Mine withstood many visits to 110 psi, but my friend broke his (the internal diaphram) with about 95 psi. Filled the intake manifold/JR charger with gas and he had to let the engine dry out for about a day. Luckily, no damage. He tore a 2nd diaphram with about 80 psi, but he caught it before it completely ruptured like the first one.
This was a known problem with the "early" AEM FPR's. Apparently, they have taken steps to correct to correct this by using a beefier diaphram.
I never had a problem with mine and my friend is now on his 3rd diaphram and hasn't had a problem with, but's running a Hondata now with peak fuel pressure around 55 psi.

Re: AEM Fuel Pressure Regulator Problems (Sonny)
Mines still sitting in a box on the other side of the room.... waiting for aem fuel rail, new fuel pressure gauge, and till I can afford injectors until I put it in... My goal is to get my fuel system DONE and tuned after all the above listed are in my room.

Re: AEM Fuel Pressure Regulator Problems (EAZY)
You can get replacement diaphragm directly from AEM.
Edit: actually, get the part number from AEM and buy it from Summit Racing.

Re: AEM Fuel Pressure Regulator Problems (JT)
i have had mine almost since they came out and the only prob i had was my fault, i put in my walbro 255 and the orig orffice couldnt handle it and caused diphram flutter and caused cels for missfires, i changed to a bigger one and cleaned up the prob.

Which orifice should I use with a Holley 255lph high pressure pump? The .100, .150, or .200?
