Duratank repair

[Newyota]

I have an older plastic Durtank that the plastic fuel/gauge housing is cracked and leaks fuel.I can't find a new assy. for the tank any ideas on parts or how to maybe make up my own set-up on the tank?

What size is the tank? 6 gal,?

Sometimes it's easier to jack up the filler cap and slide a new or newer tank under the cap.
