i just bought a obx 12:1 fmu and i have no idea how to put it on. No instructions were includedand i need some help please!

 

im thinking you didnt search becasue when i typed in fmu install in the archives tehre was like 30 threads

 

where exactly did you look? when i searched it nothing came up. when i searched just fmu 30 things came up but they were all people wanting to buy and sell them.

 

Top nipple=vacum source
bottom nipples=fuel line before fuel pressure regulator

You haven't been running a boosted motor without any EMS have you??

 

yes but i have only been putting around. i have two other qustions. one is which of the lines on the bottom is the in and which is the out. and the other is how do i do my vacum lines do i tap into my fuel pressure regulator vacum line and leave it hooked or do i un hook it and just run it to my fmu? all feed back is greatly appreciated thank you!

 

the return line from the fuel pressure pressure goes to the center nipple under the fmu .....then get another hose and connect to the other nipple under the fmu and the end back to the fpr.....as far as the vacuum just a get a t split and right between the fpr and the intake manifold.

 

thanks for the info, will try this as soon as i get off work tomorrow. do you have any pics to show any real clean ways of doing it?
