Hi all I was in the process of installing New o ring on my Interstate fuel sending unit and broke one of those 10 mm bolts that secure the unit plate to the hole on the tank almost flush there’s No meat left for the bolt to grab. Now it’s leaking. I should mention this happened before I broke the bolt. The wires in the sending unit are pointed to the back of the tank. Any suggestions or other route to fix this. Thank you
Sending unit is leaking from the bolts it's got the right size 39.5x5 O RING and 6mm nut flange. Didn't happen before and now anther problem. Am I missing something?

Drill a hole and insert a bolt from the inside.
Braze or silver solder the bolt to the tank.

Just don't forget all safety procedures for welding around an explosive vapour.
I was thinking a gasoline resistant liquid gasket, and make/seal your own.

are they a stud that is threaded into the bottom of the tank? If they are a stud you may be able to get it out with a left hand drill bit and easy out. Was the sender overtightened and the flange bent so it bottoms before the oring is compressed? |

Can't soak that bolt down with some BP blaster, drill and maybe use a easy out? If you have the ability to welt to it that is great, but for me welding around gas always makes me think of a different way of doing it.
Best of luck.

I suspect it's a 4-6 mm stud welded to the tank, and a nut holds the plate down. So no easy out or the like.
The drill a hole and apply a bolt from the inside sounds easy to do (no welding or welder here). I think JB Weld is gas resistant, I would but some on the head and bolt it in place till it sets, and you have a new stud.

The parts breakdown shows a 6mm nut.

When I have welded / brazed on gas tanks, I have filled them with argon/CO2 mix (aka "Silver Shield") from a MIG torch. Welded on them with gas inside. Can't ignite. Though vapors coming out can when they mix with air. Though it's a smallish yellow flame, vapor comes out as fast as the inbound argon mix pushes it out.
