Does anyone know where I am likely to find the spot where the Hurricane's fuel line meets the fuel tank? ITR and I are beginning to suspect that there is either a crack in the fuel hose somewhere between the tank and the Hurricane's fuel filter or possibly a crack in the fitting itself. The resulting symptoms are periodic air bubbles in the Hurricane's fuel line that aren't explainable any other way. I assume the tank would have to be drained so that the fitting or hose could be replaced. Not a pleasant thought and I'm trying to understand how complicated a job this might end up being.

Joel,
If the only problem that you are having is an occasional air bubble, why not install a fuel return line. This can be done by running a fuel hose from the fuel bleeder valve on top of the Hurricane to one of the fuel return lines going to the tank. Install a 1/64 inch orifice in the hose and leave the bleeder valve open. This will establish a very slight fuel flow that will carry any air bubbles back to the fuel tank, but it will not reduce the fuel flow to the Hurricane burner.

Gerald,
I like the $$ sound of that suggestion. I assume this works because the bypass is a vertical path which air bubbles would preferentially follow.
When we installed a spin on fuel filter this year, in place of the tiny inline one that had been installed as OEM, we also added a extension line to the fuel bleeder valve so its output could be directed into a container rather than the ground. It would be a relatively simple matter to further extend this to do as you suggest.
Thanks for the idea,
Joel

I did that about 5 years ago and have had no fuel issues since.

Apparently only Country Coach was using this approach on Hurricane systems installed in its coaches produced when ours were. I definitely intend to have this done. Thanks for the suggestion.
