    Where is the Fuel pump relay located?

    Can anyone send me a link to the relay diagrams or post it if you have the manual...

    This one doesn't have enough detail..



    Thanks in advance.

          not sure it's the same, but the fuel pump relay in my 85 318i is the one closest to the lights. it says "benzenepumpenrelais" or something like that on it.

          hope this helps.

            Looks like it's the middle one out of the three that are located near the air box...

              The wiper relay is the long black one (K10) in the fuse box. If your wiper problem is with intermittent or parking (most common), the relay isn't the cause. If the problem is with constant running (low or high speed), pop the cover off the relay and check for loose terminals where they attach to the PC board. Resolder them if they are loose.
              Be careful about identifying the fuel pump and main relays based on location. They can easily be switched around on the mount.
              The fuel pump relay has a large red wire connected to terminal 30 and a smaller red/white wire connected to terminal 86.
              The main relay also has an even larger red wire(s) connected to terminal 30, but the red/white wire is connected to terminal 87.

                Thanks, I had the constant running wiper problem and a good cleaning of the K10 relay fixed it.

                Figured out which one the Fuel pump relay is as well.

                Thanks for all the help everyone.

                  Could you take a picutre of the relays installed? Where can I find a relay diagram with the part#?? I had to take all of them out so I don't really know where they all go.
