Thanks for the replies. It is obvious that there is no exact replacement. I have found a little longer tank with the 9.5” diameter. I will post my findings for future reference.

Peterbilt 379 used a tank 08-02347 or 127.2347.

I’m going with a Newstar number  (S-25075). Looks like Vander Haag’s has them (SS S-25075)
