Replacing Fuel hoses in/out of filter - PLEASE HELP!!!

[bht2109]

Hey Guys,

So I want to replace both fuel hoses connected to the fuel filter (as well as replacing the filter itself), but I'm confused as to how to access the hose that connects to the "rear" of the filter (red arrow, in photo). Working on a '91 318is with original M42.

I know others have asked about this, but I need clarification. There seems to be conflicting reports as to which hose goes where. Please advise!

When I tug on the hose indicated by the green arrows (see photos below), it seems to pull on the hose that is connected to the hard line that is right next to the filter, NOT the inlet to the filter itself. Is this correct? If so, where the heck does the filter inlet hose disappear to??? Will I need to drop the tank?

Trying to get this done either tonight or tomorrow, so any advice asap is truly appreciated.


Thanks!!!

Can't see your pics but 8x13 high pressure hose is used in all the feed and return lines.  The return lays in a grove in the top of the tank.  The feed line to filter is kinda a pain to get to the upper clamp.  You can tilt the tank a little to help out.  Filter outlet goes to hardline right were the floor goes vertical.

Good luck.

Thanks for all your advice. Sorry the photos didn't load; I guess my account is still too young. Let me try a few Flickr links:

So let me get this straight: in the first photo, the hose with the green arrow comes out of the pump, goes all the way along under the passenger side seat, and eventually connects to a hard line right next to the filter - is this correct? You seem to be saying that this hose should actually be attached to the filter inlet. Is there supposed to be a direct line from pump to filter like this, or does the filter inlet come from that inaccessible hose on top of the tank? Just want to confirm (hopefully the PO didn't mess this up).

Also, if I want to tilt the tank down a bit, should I simply loosen the bolts #5 & #6 in this diagram?:

Again, thanks so much for your help.

Took a look at my car.  Green arrow is the return...long rubber hose across tank.. and goes to metal return line from the fuel rail.  Short rubber hose goes from fuel pump outlet to built in fuel tank hard line to another rubber hose that you have to tilt the tank to remove to fuel filter inlet.  All the other rubber hoses in the access panel are the tank vents.   Hope this helps
