fuel tank filler neck

Anybody know how the fuel tank filler neck is attached to the tank on a 72. I bought a aftermarket tank an it only has a stub. I have my old tank out and the neck unbolted but it won't come off. I assume this means it is probably soldered on. I guess i could just cut the curved portion off and get it welded to the stub.

Soldered ...and a lot of people use the old one on their new tank because the repops arent right.

Re: fuel tank filler neck

X2 use a chisel to start the cut and then follow up with tin snips. mine had the two bolts and soldered, replacement tank is brazed on, I got it off by using a dremel cut off wheel, since the new tank never had gas in it, I wasn t worried about sparks blowing me to kingdom come

Re: fuel tank filler neck

where are you cutting ?. Did you get the whole neck off including the flange. Then how did you attach the new one ?. I have a neck off of a old tank that I cut off with part of the tank still attached so that will be my donor.

I ground down to the gold color of the brazing, though the sheetmetal of the stub neck, and then ground the remaining braze as flat as I could. I had to cut some of mounting nuts off. I then used them as studs to solder the oem neck on

just unsolder the oem neck from the tank metal that is left on the neck

Re: fuel tank filler neck

I know all I had to do with my old tank was take a propane torch to it where it attaches to the tank and the solder melted off and the neck came right off. Had a radiator shop braze it to the new tank.
