1968 San Jose GT 390 Fuel Filler Neck Tube
« on: April 11, 2020, 05:50:09 PM »
I tried searching but have not been able to verify if this is an original fuel filler neck, but since it has no stampings, logo's or part numbers I assume it is a reproduction, unless I hear otherwise. Also curious what the correct finish should be. I can't tell if this one was plated or painted or both. FYI my car also came with an aftermarket fuel cap cover with a twist on cap

Anyone?

Thanks

`From the factory it had a finish very similar to the gas tank but with a higher lead content I believe. You could hit it with a gas pump nozzle with no fear of a spark is one theory.

Do you think mine is an original. It looked plated with paint. Sort of galvanized but not really

Turn it sideways so we can see the arc.

Jeff has an article in the library on how to refinish it.

Thanks Jeff great article. From now I should just check the library before I ask any questions. It's all right there. I had no idea that the tube was tinned. That is quite the process for sure. I wonder how many people follow that procedure on their restorations. Perhaps mine is an original

I need to put together another order and get the flux. I have the tin and will give it a shot.
I've done lots of copper piping over the years, so this is just bigger.

You can tell from the picture that the filler neck is not the original finish.If you read my post then you can see why it is easy to tell. Yours looks painted . Regardless it is not the original finish which looks substantially different.

Thanks Bob Should have any stamps on it to identify it?

I thought the same, it looked painted (scratches).

Thanks Bob. I will have to see how I do on the lead skinning. Challenge accepted. Something I have never done before, but a touch that cannot be duplicated as far as I know. The end result looks great and the only part on the car with that finish as far as I know

Would suggest tin rather than lead ;)

Good thing about attempting this is that if you mess up you can reheat it, run the mess off the filler tube and try again till your happy. If you have more than one filler neck I would do a number of them all at the same time and pick out the one you like the best and sell off the rest. Not going to cost you any more in product - just a little time.

Dad always taught me that you don't make one of almost anything when doing things like this. Just what has served me well over the years

Great advice from you and dad Jeff. Thanks I will try that
