BMW 325 Forum : “do you give advice on installation of parts”

take it to the dealer and have it done right

Its kinda difficult on your m20 engine. The intake manifold is ridiculous. Itll probably take you a few hours to remove and re-install the manifold but other than that its a pretty straight forward procedure. Go to amazon.com and buy a Bentley manual for your e30 bmw. Bentley is the brand of book. e30 is your chassis code (84-92 3 series)

Its around $30 and will save you some heartache. Good luck.

It's easy. At the end of the fuel injector rail you will find the regulator. On the 1 side loosen the small vacuum hose  by pulling it off and the other end the return fuel hose by loosen the the pype clamp. Loosen the two  6mm boltz and pull the regulator out of the rail. To fit the new one, reverse the above steps.   

i second this thought. get a bentley!!

Pretty sure you need to pull the intake mani to get to the injector rail.

Are you guys being serious? DO NOT REMOVE THE MANIFOLD! This should take maybe 5 minutes to changed. It's a small black cylinder on the edge of the fuel rail, there's a hose going into it, and a hose below it coming out of the fuel rail. It can be a little messy but that's it.


I assume this is a remote mount adjustable FPR? All you have to do is,unbolt the FPR, and disconnect the hosesI would replace them both if I were you, new hose clamps too) The hose going into the FPR is the input hose, the new APFR should have instructions that tell you what is input and what's output. Out of the output you need to run a new hose to the adapter that should have come with it, bolt the adapter to the fuel rail, then all you gotta do is find somewhere to mount the FPR.

If it's a stock one you're replacing it with, same thing but simpler, unbolt the FPR, disconnect the hose, and replace.
