Info needed on CMP(?) fuel tanks fitted to SAS Jeeps

[Phil Waterman]

The fuel tanks with the top fill location where common to both the Ford and GM Pattern 11 and 12 FAT. This required opening the door to refuel through a hole in the floor. Can you imagine pouring gas from a 5 gallon flimsy in the dark. There is a GM field service bulletin about problem of getting your hand around the filler cap because the hole through the floor was only 4” later increase to 5” across.

The Photos are from both the Ford and Chevy Parts books.

As to the fuel selector valve this is a stock fuel selector valve common to CMPs, They are still used on duel tank trucks today and are available from various suppliers. The only difference is in the handle which on CMPs was a cast part and now is a stamped steel handle.
