Sealer to use on a gas tank?

[BLK 68 R/T]

What is a good fuel safe sealant to use on a gas tank? Plan on cutting a hole in mine to mount an in tank fuel pump and trying to figure out the best way to seal the access cover that will need to go back on to cover the hole

Permatex aircraft sealant. Sold at all the parts stores.



Works great. I used it on my tanksinc drop in pump after the original seal leaked. Been working great ever since.
