Thanks for your many inputs, I have decided to brake down and get a new tank from Drake using their sending unit which will work with the original 36 gauge which I have, I can use my 35 filler neck and will add a vent tube as Tom has illustrated in his post. Thanks again, Jim

tudor Bill- There are a couple of ways to do this one of which I have described above. However, the absolute best way is by running a separate line from the top of the tank. Enclosed is a picture of a '36 tank with a top venting hose. It is nothing more than an elbow with a fuel resistant hose attached. The hose goes up to a tube welded to the outside of the fuel neck (additional picture). The tube then enters the neck and is under the gas cap. With this arrangement you can fuel the tank as quick as the pump will deliver the fuel without you or the car taking a "gas bath." Tom

I solved a similar problem with a kitcar I built in the following manner. The new fuel filler pipe went where the fuel gauge sending unit had been located so the sending unit had to be relocated. I cut the holes for the new location of the sending unit in a flat area on the top of the tank. I used an appropriate sized hole saw to cut the center hole. I then drilled the surrounding smaller holes slightly smaller than the holes in the sending unit housing to accomodate sheet metal screws. When I attached the sending unit to the tank I sealed the joint between the two with J-B Weld. I owned the car for 22 years after that and never had a fuel leak. Hope this helps. A vented fuel cap was used. I started with a brand new tank that had never had fuel in it.

Tom- I can't speak for others but my experience with what you have has resulted in fueling backups. Meaning that when you fill the tank you end up with fuel backing up (because of the trapped air in the tank being unable to exit due to the incoming fuel)and washing all over the fender and the person filling the tank. Very s-l-o-w filling will help but not solve the problem. Tom

It might be a good time to consider installing a plastic tank that will accommodate the sender. Old tanks and the "new" gas don't mix.

Check the vendors. There are adaptor plates that allow you to use the different sending units. I just looked at two different ones, Drake and Mac's. Depends on which way you are trying to go. Hope this helps, Ken

Gary- Check eBay item 320597155923. I think this is what you are looking for. Tom
