:S Duuh, SoCal finally put it in real world figures. Where is the beef.
As far as you 6.2 gas jockies and your small tanks. i got an F250. 2012, short box 2WD crew cab and it has a 37 gal tank from the factory? Right or wrong?
35 gallon from factory for gasser Super Duties from 2011 and up to at least 2016. I think 2017s may have 34 gallon tanks for gassers in all cab/bed configurations from what I have read.
With that said, there IS or at least should be a leftover "air pocket" in the tank at 35 gallons to allow for the gas to expand.. So if you filled it up way past the normal click off on the gas nozzle it may be possible to stuff more than 35 gallons in..
HOWEVER, do so at the risk of damage to your vehicles Evap system!!
