Fix fuel neck leak with JB Weld? Fuel tank cement? Other?

This is the rear tank filler neck on a '95. Couple of rust-induced pinhole leaks right where that clamp goes that supports the neck to the underside of the bed. Metal clamp on a metal neck, rust... I've had WTB ads up on all the forum sites, craigslist, etc. with ZERO replies. Discontinued at the dealership, nothing at nearby boneyards. So I'm looking at a repair. I remember using some purpose-made fuel tank repair epoxy on a gasser car 20-ish years ago, and it held good. I'm thinking something like that, or maybe JB Weld will patch it. Any other possibilities?

The shiny stuff is Fluid Film I have soaking on it, to break up the rust. Bet a nickel I'm gonna de-rust the whole thing, and paint it after the repair, and use a layer of bike innertube between that clamp and the neck for the reinstallation.

I would try the JB weld on it as that seems to work for a lot of folks on the bottom of the fuel bowls. The JB Putty would probably work well too. Cheers!

Thanks Patrick. I ended up taking it to a buddy around the corner, and he spot-welded it for me. Primed and painted and back in the truck. Won't know if it holds until I fill that tank again.
