AEM FPR Not Reading Pressure

[BoostedDelivery]

Hey All,

Looking for some help. I just installed my new AEM FPR Kit from MAP (I got the tank to rail kit and the AEM FPR install kit). I have no leaks from what i can tell, but am not getting a reading on the liquid filled gauge. The car runs, although a bit rough, but it hasn't been tuned yet. Was taking it in on Friday for a dyno tune but want the gauge working before i go. I have a 95 GSX with a built bottom running 550cc, AEM Fuel Rail, MSD wires, NGK R plugs, PIT EBC, HKS SSBV, Injen intake, Big Evo III, the parts listed above, and have my Boomslang wiring harness for my soon to be tuned E-Manage Blue all new(hence taking it to get tuned). Sorry for all the info but wanted to give as much as I can to get quick resolution.

Please let me know if you need more.

Thank You

well theres a little delimma... I read, to get the reading you must plug the hole, then set the gauge to 43 psi, then hook it up to intake manifold. But i've actuatly tried both. How lonk does it take to read? I've let it be connected for up to 5 mins or so and left it unconnected for about the same. Then I've stood there with my finger over the hole for up to 5 mins too... ran out of caps..

In case any of you wanted to know the fix. I had the FPR on backwards. Duh... It seems that the down facing port MUST be used for the return line.
