97 f250 the fuel tanks on them the front is 19 rear is 18. If that correct

also you gents with this year truck when the fuel gauge hit red rougly how much is in the tanks. any help would be great

 

Tanks are roughly that.
When my needle is centered on the "E" line, I have two gallons left (both trucks)... doesn't mean yours is the same.

 

OK I figured every truck diffrent thank you

 

i thought both tanks were 18gallons but close enough. when my truck is at 1/4 tank, i used 12 gallons. run it when it just hits the e, still have a few gallons but i woudnt run it that low. sucks alot of dirt and junk from the bottom of the tank. had a driver cost me alot of money because he was an moron and kept running it out of fuel.

 

I intentionally run both tanks dry just before changing the fuel filter.

 

my gauge is screwy also. i can fill up the guage maxs out, but drive it 25 miles and its below full, drive it 150, and it shows 1/4 tank. ive made myself drive it to 260 and filled again. i can hear my dadys voice "you dont ever wanna run a diesel out of fuel". is there a fix to this?

 

Yea consider 1/4 tank as empty
