With a little research I determined that the Purolator Facet FEP 2042 is an equivalent. Just to have a spare around, I bought one on eBay for $30 a couple of years ago.
Yesterday I got back to working on my K75 project bike. I'd left the fuel pump out for quite a while and it was frozen - FARK!!!
Now I'd have a chance to see if the $30 solution would work. Sure enough, it did.
It only took a few minutes and was very easy to do:
1) Remove the old fuel pump. a) Undo the hose clamp and take the fuel hose off. b) Undo the electrical connections(7mm and 8mm) c) Pop the plastic clips at the front and rear of the mounting ring. (You don't need to undo the 8 nuts on the plastic mounting ring.)
2) Once out of the tank, slide the old fuel pump body out of the incredibly expensive rubber vibration mounting ring.
3) The diameter of the FEP2042 is much less than that of the BMW fuel pump. There's a section of submersible fuel hose that comes with the fuel pump. How convenient. I cut it's length to slightly less than the diameter of the new fuel pump, ran a nylon zip -tie thorugh it and wrapped it around the new fuel pump and secured it with the zip-tie. With a few minutes of careful cramming I was able to get it nicely lodged in the vibration mounting ring.
4) Attach the pre-filter that comes with it to the bottom of the new pump. If you fold it up a bit it will fit nicely in the fuel pump "pocket" of the gas tank. Insert your new fuel pump assembly into the fuel pump hole in the tank and make sure the clips pop into place.
5) The nozzle on the top of the fuel pump has a slightly larger diameter than the BMW one but the hose will fit over it. The IBMWR instructions say that the BMW hose clamp is too small to work. Not true. If you drop the hose clamp on first and then slide the fuel hose on you can use the old hose clamp.
6) Wire it up. Cut the ring terminals off of the black and yellow fuel pump wires from the tank. Put female blade connectors on each wire and crimp carefully. I used bare metal ones - who knows if the plastic on covered ones would dissolve in gas. Attach the black wire (ground) to the narrower blade terminal on the fuel pump. Attach the yellow wire to the wider blade terminal.
Vroom, vroom....... and off you go.
I have a temporary tank on that bike now. When I move the real, freshly painted tank onto the bike and have my new fuel pump out I'll try to remember to take some pictures.
The price of these fuel pumps has gone up drastically. Now they're a whopping $36.95 on eBay!
If you're the paranoid type who likes to travel with one of everything under the sun (Shogs
) this fuel pump wouldn't take up very much room and you could take one along as a backup.
