Just curious what fellas are using for exposed gas caps on their rods these days.
I may still go with a door, but I'm thinking an exposed chrome cap may look good.
Not into billet though, but never know.

How would the filler neck attach to the body if going exposed cap?

On a 38 Chevy, this grommet goes where the filler neck passes through the fender. The filler neck does not physically attach to anything besides a large hose which attaches to the gas tank on the other end. It simply passes through the grommet/fender and has never been a problem. Topped off with chrome cap. Gas Filler Neck Grommet (Except 3 Pass Coupe and Sedan Delivery)

Thanks Bob.
I guess the hose holds it up and the grommet keeps it from jiggling.
How far thru the grommet does the filler neck stick out approximately?

I'm not near the car now, but I'd guess not more than an inch. Just enough to put the cap on. Given your skills I suspect you'll come up with something a bit more elegant. Since the filler neck can connect to the tank via a hose, you could weld the neck to the body for a cleaner appearance. I'm thinking an end result sort of like what you did with the mirrors.

Thanks again Bob.

To weld to the car is a great idea. But I would need one made from stainless steel.

Searching online has some weld in style bungs and caps.

Vented caps....is it the middle hole seen in the second pic of this eBay ad?
I could weld it up easily if it is.

Something like this? Gas Filler Neck -Universal Chevrolet Style

Yes, that second pic looks right to me. Looks like what I have and a whole lot more affordable than the stainless option from chevsof40s.

Chevs of the 40's are pretty proud of their products, looks like, lucky I have a Chrysler, ha....

But your welding idea is spot on.
I currently have an oversized hole and I can weld a disc around the filler tube just like the mirrors with a nice fillet of weld at the inside corner. Then weld it all into the fender.

Looking forward to seeing the final result. I know it'll be done to the highest standard.

Could be a while. Need to get the body back on the chassis to see how I will build the new tank. Hopefully, I can leave it right there in the factory location.

Will you be putting an emission compliant drive train in? IE EVAP system in it. If so you will have to use a late model style cap.

That's why I need to plug the vent hole on the cap I get. Vent is thru EVAP canister. Nice, no fumes in the garage.
