fmu install pics for 5th gen prelude(i did search first)!!!!
i installed a vortech fmu today. and the pressure shot up to near 80 psi. i also have a aem fpr. before the pressure spike i have been driving my car w/o the fmu. the pressure was around 40 psi. i am not sure if the fmu is hooked up correctly. does anybody have any diagrams for the prelude. i found a civic diagram. i guess mine should be the same.

the pressure is supposed to do that with an fmu. as soon as it starts seeing boost it will "up" the fuel pressure according to boost.
vacum port on top goes to intake mani
fuel port on side goes to stock fpr
fuel port on bottom goes to return line.

your pressure should be around 40 at idle, if its higher you have the lines reversed probably.
