Fuel Tank Petcock Question

On my fuel tank petcock, where the fuel line attaches, there is a metal elbow that, on my KLR, has always pivoted. I always assumed it was designed to do so.

I've found that I can easily pull that metal elbow out of the petcock with just a tug, leaving just a hole in the petcock.

I'm guessing that elbow is somehow supposed to be secured to the petcock and I shouldn't be able to pull it out.

I think it might have contributed to a stall I had last night. In true KLR fashion, I put a zip-tie around it to keep it from coming out on its own until I find out what's up with it.

Any info would be appreciated.

Lockjaw said his did the same thing. I got mine out of the box in the rafters and checked it and the elbow did not move. Seems to me they are supposed to be solid, but yours isn't the first. T.

The elbow the fuel line attaches to does pivot but mine has never come loose before and I've had the tank off countless times.

Thumbs up

FYI mine does the same thing, comes completely out, and pivots. thinking I should zip-tie it for now?

I guess I'll just stick with the zip tie: it seems to do the trick. Nothing's leaking and it's running fine. On the other hand, seems kind of "not right." Is there really any reason for the elbow to pivot when there's a long, flexible hose attached to it? Maybe a good surface cleaning and a couple of carefully-applied dabs of JB Weld would be in order?

Are you on a 08' or newer bike? Mine is solid on the 06'.

The elbow is just press fit into the petcock. I had this happen last fall on a KZ 305, with nearly the identical petcock. I put a coat of Permatex Liquid Solder around the elbow and seated into the petcock with a set of Channel Lock pliers. The Liquid Solder is inexpensive...about 3 bucks @ the car parts store. It's impervious to gasoline and heat, and seems to have withstood vibration.

While I doubt this product was developed for this app, it seems to have worked for me. JB WELD may be as good if not better, my experience is limited to what I relayed about the liquid solder.

Thanks for the tip on the liquid solder and the fact that the elbow is just press-fit into the petcock, vatrader. Knowing that nothing is really amiss other than the fact the elbow it worked its way out, I'll go ahead and get it secured back in there. If the liquid solder worked for you, I'll probably pick some up and give it at try.
