Does anyone have a serviceable left fuel tank for a 1965E C150?

Thank you,

I have one that I replaced on my "E" model because the threads for the fuel drain are somewhat messed up. Otherwise it's fine. It didn't leak and the drain threads are the only issue. I'll be at my hangar tomorrow and will take a closer look. I'll take some pics. if you like.

If Elliot doesn't, I do.

I just got back from my hangar. Here are the promised photos. You might be able to see the stripped out threads where the fuel drain goes. That is the only problem. Other than that the tank is serviceable with a little work (corrosion at the filler neck). $0 plus shipping will do it for me. I'll build a wooden crate for it.

I wonder if that can be fixed with a Heli-Coil?

I have used heli coils to repair spark plug holes (on my truck) and it worked great. It seems they should be able to hold up to static pressure of fuel in the tank. I'm somehow doubtful that it is an approved procedure.

Hi,

I would first try running a sharp tap 7/16-20 and straighten up the threads. the CVA-170 seals on a O ring not on the threads and this is your best option.

I would think it would be a minor repair and required only a log book entry.Or not.

1/8 NPT is the next option or have someone tig weld a bead and re tap the hole.

Or call the experts at:

I have seen U-tube videos of mechanics installing heli coils in aluminum oil pans as a repair for stripped out drain plug threads. 1. Be leery of anything you find on the internet. 2. Be especially leery of anything you see on the internet on u-tube.

Interested in knowing if this is an approved repair.

I've got to run to New Bern next week. Will ask my AP if he is around.

Thanks

This brings up another question. Can aircraft engine spark plug holes that are stripped out be repaired with a heli coil?

Can ANYTHING on our airplanes be repaired with a heli coil? Someone in this group must know this. Anyone?
