I know LMC sells one. I couldn't tell you honestly. I haven't filled the tank up once, as it has just sat in my drive way since.

That is correct. The '67-'69 trucks' tanks were rated at 19 gallons, but once the emission-control tanks came along, those got rated at 18.5 gallons.

My 69/70 F250 (both) have a 17 gallon tank in the cab. Well, with gauge on empty, the most I've ever put in was 17. I can't get very far on a tank of gas though. One of these days I'll add a second tank.

Since we are talking tanks does any one know the size of the extra tank that came on the 69 100s? Ive got an incab tank and one underneath somewhere.

My 68 F-250 has a 25gal 2nd tank that came on it. It was an option. My in cab tank is rated at 19.5 Gal. (Info out of owner's manual.)

The one on my 69 F250 Camper Special is around 35 gallons. Don't know if that was used on your F100.

Measure it. Height x width x length = inches squared.
inches x 0.004329 = gallons.

Example: 12 x 12 x 35 = 5040
5040 x 0.004329 = 21.8181

21 3/4 gallons if the tank is 12 inches by 12 inches by 35 inches.

Is the LMC version under the bed or in cab?
