Question about Fuel tank size
I own a 1994 f150 4x4 with a 133 wb, and the factory manual tells me a have a 19 gallon fuel tank in the front and an 18 in the back. But I recently ran the front one dry to test what it was, and it filled up with 16.8 gallons. I know that a 16 gallon was an option for shorter trucks, but was a 17 gallon an option?

You're always going to have a little left in the tank even after it runs out. 1-2 gallons of fluid spread out over a 1.5x4 foot area isn't going to be enough for the pump to pick up. I did the same thing with the rear tank on mine. Took 17.4 gallons to fill it back up after I ran it empty.

My former '97 F250HD ext cab shortbed had the '16.5f/19r' tanks, or that's what they'd take, approximately. After the front tank gauge went INOP, I simply ran it on the front tank 'til empty, then switched to the rear tank.
My current '95 ext cab longbed has a larger front tank, same rear tank. BUT when I bought it, the front tank pump was INOP so I had only the rear tank for the 1100-mile trip back home at 11mpg, Having to stop every 150-175 miles got old real quick! When I got home, the front Tank/Pump/Sender was replaced. Tank because it was a rusty mess... As long as I had the bed off anyway (easier to access tanks than doing it any other way), I replaced the rear pump/sender 'just because', along with new fuel filer (old one was almost totally plugged with rust)
