My trucks are likely 20. When they are setting at about 1/2, they will hold another 11 gallons. At 1/4 they hold about 15 gallons.

The neck filler probably holds more than you thought, I'm 99% sure they are 30 gallon tanks. I think it was 93 or 94 before they switched to 34 gallon tanks and they never used a 32 gallon tank to my knowledge.

Pretty positive my truck is a 30 gallon tank as well.

In my 89 factory service book it says 30 gallons (or 68 liters) is only option on the 89's.

Regardless of whether its 30, 32, or 34 - at these prices its a shame.

Most I ever put in my tank was coming up here to Mi from Tx...Low fuel lite came on ~ 1030pm in a snow storm. 1/2 hr later I found an exit with a station that had diesel. Gauge was needle width above E line...27.75 gal later and $37.50 ( this was over 3 yrs ago :CRY::CRY::CRY: ) I knew I had a large tank.
BTW - tranny was in good shape then and I cruised at 70 for 618.8 mi when I filled up...Best mileage I ever got.
