i need help installing my fmu on my 91 crx si, i know a vacum line goes in it , and fuel goes in 1 thing and fuel comes out the other , but vortech dont have it marked, and what do i do where the old fuel went in and out

side port goes to the stock FPR return line, the bottom port goes to the stock fuel return hard line to the gas tank

so basically you take what ever is sticking into the bottom of the FPR and stick that into the bottom of the FMU. And just find some piping and connect it to the side of the FMU and plug the other end into the bottom of the FPR???? That's it?

 

sorry guys i still dont understand, i know where the fpr is, but on one side if the fmu there is a small nipple i think that is where a vacumm line , but on the other side there is 2 other big nipples one coming from the center, what goes in there, then there is another one on the bottom what do i plug it 2

 

Come on guys , i know some ppls have put this on

 

if you are looking at it from the side, the port on the very top get t'd into a vacuum line. the side port hooks int o the fmu. port on the very bottom is the return line to gas tank

 

 

nice diagram. this should be on here permanately

 

very very nice so much clearer, thanks
