Petcock attachment

I have a 1981 Honda Express N A 50. There is nothing but a hole in the gas tank where the petcock is suppose to attach. What goes into the tank that the petcock attaches to?

there should be a threaded piece of pipe sticking out of the tank, that is welded to the tank

Re: Petcock attachment

Thanks for all the comments. What I’m trying to find out is how was the bung originally attached to the tank, since whatever was there has been removed. There is no sign of welding or anything else that would indicate how it was attached.

Re: Petcock attachment

So, are you saying that cock should go in the bung hole? Maybe this should be off topic or on another site altogether.

Re: Petcock attachment

Remember back when Wendy's had the tables with the antique newspaper ads printed on them? There was an ad for a bunghole borer.

On the right is the oil line.

Re: Petcock attachment

Doesn't look as if it was ever welded .

Maybe was a grommet with a press fit connector ?

That might be worth checking into .

Maybe something like :

With something like a barbed shut off forced through it or a threaded petcock screwed into it .

Re: Petcock attachment

Doesn't look like it was ever welded for sure.

Re: Petcock attachment

Inside of the hole threaded?

Re: Petcock attachment

The mia bung was not "welded" on it was Brazed on and later twisted/broken/sheered off. To verify for yourself just hit it with a wire wheel and you'll see the braze yellow or whatever color they used, looks reddish.

Re: Petcock attachment

what pat said, second that. it doesnt look like it was ever welded cuz it wasn't it was brazed and is broken off. braze a new one in or just seal it up and run off the other hole. Or if that other hole is for separate oil reservoir just drill em together and run premix with an expanded gas capacity. Or get a new tank.

In the past I just welded a spare barrel adjuster screw onto a hole drilled in a tank, and that totally worked

Also to the above double entendre theres a package store I think it was Salem; coast north of boston anyway called Bunghole Liquors. Nice.

Re: Petcock attachment

oh, it's basically just a screw with a hole down the middle. I'm not suggesting you should use that exactly - just explaining a simple creative solution to macguyver some shit with some parts alotta moped folks have laying around, they come on your throttle and carb top and brake cables etc etc. and when you buy new cables, you usually get new ones so you got some of these rando pieces around that are effectively little metal tubes, and honestly all you need to get a fluid out of a metal container and into a fuel line is a little metal tube

so yea, in short, anything works. grab a hollow bolt, or a barrel adjuster, or a piece of metal tubing or a coupler nut, or a drilled out grease fitting or a proper hose bung --- anything roughly the right size to jam fuel line on and have it get outta the tank.

Re: Petcock attachment

It does look like it had a "welded bung" look at the picture at this site. CLICK HERE

I would just braze in a barbed fitting and be done with it. Make sure you clean out the gas vapors/residue before putting heat to it

Re: Petcock attachment

How aboot a Rivnut / nutsert. If sealed with a fiber seal it might work.
