quick disonnect failure - need quick help

[GJBushman]

While replacing my battery one of my quick disconnects failed and I can no longer use it. I will order a suitable metal replacement disconnect but in the meantime I need a repair so I can get back on the bike. What am I looking for when putting in a straight piece with clamps? What is the hose diameter and can I get the correct length in just a single fitting or do I need a longer piece of tubing? Thanks for your help gurus.

No guru here, but I believe its a 5/16th inner diameter fuel line. Try to get a 3" brass straright pipe with opposing bards. Do a search for "quick disconnects" and see a thread names "QD Failure? Not me. . .!" (Sorry, but I don't know how to attached the thread to this reply). It's got some good pictures and explanations of the problems you're now having and good solutions.

Good Luck. BMW QDs suck!

Thanks for pointing out that thread. Unfortunately the 5/16 connector is not available at my local Home Depot. 5/16 ID is not a popular size. Can't find any tubing that size either. I'll keep looking.

5/16 ID is not a popular size. Can't find any tubing that size either. I'll keep looking.

The fuel line is 8mm x 12mm, which converts to about 5/16" ID by about 1/2" OD. Since the QD (and any replacement) needs to go inside the hose, you need a piece of tubing with a 5/16" OD. Try a plumbing supply store or your local hardware store. Ideally, you'd like a barbed fitting but any tubing will work. You could also go through the plumbing parts bin at Home Despot - you almost certainly will find something that fits. I'm sure you know that you should use FI clamps, not the standard worm-gear type hose clamps.
If you're planning on using Omega QDs for the permanent fix, they ship very quickly; I got mine 2 days after ordering.

Solved. Found some brass nylon fuel line unions at NAPA. They worked out great.

They are designed to fit in the inside diameter of 3/8 nylon fuel line (see pakaging), which I assume is an OD measurement. They fit into the 5/16 inside diameter of the 1150R fuel just fine, not too snug. Could have been a bit longer but I have plenty of clamping room. Not completely road tested but I'm not expecting any problems.
