Crusty Rusty Leaky Squeaky 67 Step

Muffler shops only go so small- my filler adaptor is the top rail of a chain link fence!

Looks great, Vic. I like the way it all lines up.

...believe my filler tube is 1.5" or 1.75?? gonna remeasure, my tank is 2", so i may comb a few junk yards to see if i can find a 2" tube like the one you have. I know the muffler shop can make an adapter but a 2" tube would be nice.

The check valve mechanism is in the gas cap. When I leak checked the tube, I put the cap on and filled it with water. Nothing came out around the cap with the assembly upside down. The vent would only require a rollover check valve if it's open to the atmosphere. This setup carries the vent from the tank all the way back to the top of the fill tube.

I welded out the vent tube and the lower section of the filler tube first. Then when I mated the upper and lower parts, I wrapped a wet towel around the upper portion where the plastic insert is crimped. Since I couldn't remove it, I wanted to be sure the heat transfer didn't melt it. I'd weld about an inch of the gap, then quench the area with the wet rag. Repeated until the entire gap was welded. Voila, no problem. For heavier items that require more amps to weld and have heat sensitive parts nearby, I'll suspend the delicate part in a cup of water, leaving just enough room above the water line to weld. But for this thin material, a wet rag was sufficient. At one time I had some putty like material that was marketed as a heat fence, but the crap wouldn't stick to anything and was only good for making a mess.

This 2" filler tube came off a late 90's to early 2K Blazer or Jimmy.

Chip is right, finding an adaptor might be tricky.
