    Hi there....Rotax did have a kit you could order.  You will need 2, one for each pump.  Check to see if they are still something you can order.  The number is on the picture. 

    Cheers

    A quick look at Leading Edge Air Foils got me a very unhappy answer.  I did not bother to look at Lockwood.  Frankly, I'd simply splice the original cable to the length you need.

    I believe I have tracked down the part number, but can’t be sure until I buy one and try it.  It appears to be Aptiv 12162017.  The next problem is that I am not able to find a matching male connector.  It appears this is used only on OEM parts (most places say it is used on auto air conditioning compressors) and the male part is built into the unit as with the Rotax fuel pumps.

    Wow, that’s a spicy meatball!  I checked Lockwood and same price.  If found the female part that goes into the pump, but I have thus far been unable to find the corresponding male part to connect to the engine harness.

    I probably will end up splicing.  I just hate to mangle the factory harness if I don’t need to.  If I ever wanted to sell the engine, it is always nice to have things be original.

    To summarize what I found and close out this thread.

    The female connector is made by Delphi/Aptiv and is part number 12162017 and apparently was used by GM back in the 80s and early 90s for air conditioner compressors and used by some heavy trucks and, for whatever reason, is used by whoever makes the fuel pump that Rotax uses.  The additional locking part for this connector is number 12124824.

    I contacted Aptiv and asked the part number for the mating male connector and their reply was that they don’t sell that part.  I then tried the same with Mouser and chatted with a technical rep there and he said that the mating part is a “manufacturer built-in” part and Aptiv only provides the drawings for that part (which I found), but it is up to the equipment manufacturer to build the male mating connector into their part, as was done with GM air conditioner compressors and the Rotax fuel pump.  I assume Rotax had to pay someone to make a mating loose connector so they could sell their 881304 connector kit.  This likely explains why it costs so much.

    FYI, as of today at Mouser, the female connector side can be had for less than $15 for all of the parts assuming you buy the high end silver plated terminals which cost $1.30 or so each.  With standard terminals that cost 50 cents each, the total cost for a connector is under $10.

    It appears there are only two options:

    1. Pay $150+ for the Rotax kit with four connectors and pins or

    2. Cut off the connectors from the factory harness and use those on the fuel pumps and then splice wire in between.
