Spruce has them too, I don't think the pic represents the actual product:

These are too big. I would have to drill out the flange holes to 1/8. The van's tech assist rep said that it wouldn't be a big deal to drill these out, but I don't want to risk getting metal shavings into the tank.

I tried to find the 3/32 needed for the existing hole sizes, but just couldn't find any anywhere.......

I will try simply using countersunk blind rivets dipped in lots of proseal, with lots of proseal between the flange and tank skin, and squirting a good amount of pro seal through each hole just to try to cover the rivet as best I can. After all that sets, then try the pressure test again.

Then, and hopefully this wont be the case, if it fails, I can simply open it up through the fuel sending unit and buck in some solid rivets.....
