VCCA Home Forums TECHNICAL - 1945 AND EARLIER 1933-1936 36 Fuel Problem

Hi all,

Have a 36 standard and started it this weekend and notice gas leaking from the fuel line going into the Carb. Realized the brass nut (compression fitting) has split. Also when it was running it would only run normally with the choke pulled partially out. Are these part of the same issue, the broken compression fitting? Or are they 2 separate issues.

Also looking on the filling station and don't see a replacement fuel line from the pump to the carb (they do have the tank to the pump) anyone know where I can get one? They do have the fittings but have not tried to remove the compression feral and don't know how easy it will be to remove (fuel line is original). Any ideas?

Thanks for your help

It can be a little tricky but the compression ring can be removed and replaced. Once the ring is split the nut can be removed and replaced as well. Since I don't know the tools that you have available don't know exactly what you would use. A three cornered file, fine saw blade (hack saw?) or ??? Be very careful and try to not touch the tubing. You will need to split at least two places. It is necessary to go nearly all the way through to weaken the ring so it can be split.

I suspect that you have some buildup of crud inside the carburetor. Liberal use of a good cleaner may remove it. If not then the carb needs to be taken apart and either the individual parts cleaned or replaced.

Metal fuel line is available by the foot at your local auto parts store. You can make your own fuel line if you have the tools to properly bend the fuel line to the correct configuration.

If it were mine and I didn't have the tools I would buy a min tube cutter. Cut the line next to the present sleve, slide on a new sleve and nut, pull the line "up a little" and reconnect it....or cut more off and add a glass bowl gas filter.

Shortening the line is definitely an option. Since the line is original I personally would try to save it with only changing the sleeve. IMHO, Much better to have one not leak than try to keep it original.

Thanks everyone. tools are not an issue, I should have what is needed. if I can get the feral off I can either try and "stretch" it or go with a fuel filter (which I never thought of) thanks for your help.

You might get a new fuel line from Jim Carter. They are in the parts book.

Hello again, So I have a new fuel filter unit but eh problem is, it does not fit with a regular 1/8 hex nipple as the horn is right there. I can use a 2 1/2 inch brass nipple to extended it out but my question is, while that put a lot of stress on the carb? (any chance of that cracking the inlet on the carb?)or is there a more preferred way?

Thanks
