You could put an electric gas gauge on, Like I did with my Roper!! LOL :trink40:
Yeah I tried getting one for my Super 12, But they said it had to be special ordered. There's not very many tractors that still use the 1 1/2'' filler neck.
I believe all sears steel gas tanks are 5 1/2'' deep. You can still get them, They just don't keep stuff on the shelfs anymore. I see them pop up on ebay once in a while. - Brad
