i bought my f22b1 AEM rail used and it came with no fittings.. I'm going to use a aeromotive fpr.. so what's the size of the thread to plug up the AEM rail Fuel pressure regulator hole??

thanks!

Is it the same size as the hole you can thread a fuel pressure gauge into? If so, it should be 1/8 NPT, if not, I have no clue :dunno:

nah it's the fpr hole... the 1/8 hole for the gauge is already plugged. on the rail there's 2 small holes for the stock FPR to bolt on to and the center hole for the fuel to go through.. and there's threads in that hole.. thanks!

Is it larger than the 1/8 hole? 5/16 or 3/8 NPT maybe?
