Fuel leaking where fuel rail and injector meet for making love

[Arredondo1]

Got a chance to continue working on the 88 k75 and finally got my gas tank completely assembled and installed. Went to fire up the bike and gas leaked all over the place.Gas was coming out from where the fuel rail meets the injectors, I deduced that the injectors are either not sitting correctly or they are not "drinking" their prefered beverage. What steps should I take next? I looked here and my fuel rail doesnt have any clips.

Where can I find those clips and could that be the issue?


I know the injectors are new, as well as the o rings. I have the reciept for the injectors from the previous owner as well as the old injectors that were taken out. Maybe they were just mounted wrong?

If you have run this engine, the clips are wherever you disconnected them from the injectors.

 Otherwise, you'll need to buy some.

Never ran it, only assembled the tank since thats all that was missing when I bought it. This was someone else's project that I took over. Where do I purchase them? I cant seem to find them.

Been doing google searches, pretty sure Im not searching for the right keywords.

nearly any bmw dealer.   look up the part number on realoem.com or any dealer site.  buy from dealer or google the part number for other sources.

You can find them here for sure

Start by putting in your bikes model and year and the last six digits of the VIN

That way you will be fairly certain any parts are the right ones for your bike

Ok i forgot to post an update, clips went in fine and injector 2 and 3 no longer leak, however injector 1 still has a tiny leak. The injectors came with brand new o rings, maybe that injector had a bad o ring? If its the rail, how should I go about checking the fuel rail for this tiny leak? Or more importantly what ways are there to seal the fuel rail?

however injector 1 still has a tiny leak.

Don't go off the rails with diagnosis. Reinstall injector #1. The slightest application of lubricant applied on the o-ring might help it seat correctly—silicone grease, WD-40, motor oil, etc. You name it; it either has been recommended or condemned for use on injector o-rings.  :giggles
