Title: Replacement fuel Pump/FI relay part #?
Post by: Originalowner on July 15, 2015, 09:24:46 PM

Specifically the black 5 prong relay in the front left spot of the relay box on my 1986 K75C.  My original relay has last digits of 1 459 574.3.   Looking at parts Fiche I see a black 4 pin relay 1 459 677 in that place of the relay box.

  I can find the exact old part number relay for sale removed from old bikes but not a clearly identical part number from BMW.

Any one help with my confusion?

And first time poster here!....howdy to all!!

I have ordered part matching my original from eBay last week.   Still strange that this part number does not exist on parts fiche I search or you listed.  Google of part # no help either.

The eBay link sold in March...but was a better deal than I just got.

The printed part numbers are probably Bosch manufacturer's numbers, not the ones BMW uses on the fische.  The FI relay is 61311373585.  Your only possible source is used since the part is discontinued.  The relay is special because it's a DPST (double pin 87), whereas the other relays are SPDT (87 and 87a pins).

Robert:  the part number you list IS AVAILABLE, but it is a blue or yellow 4 pin relay found center and right in the fuze box and not similar to the 5 pin relay (left front of fuze box) in my bike or the BMW labeled relay I source from similar old K75 bikes.

My part is BMW format part# seems to be 61311459574.3   Not sure all are labeled with the .3.
