I have a 1990 Mustang conv. It was a 4cyl and was converted to 5.0. My question is this, does Ford use the same gas tank on both cars? How many gallons does it hold. If it is two different sizes, how many gallons for each? Anyone know? Thanks.

 

Yes they are the same 25 gallon gas as all mustangs, The new stangs maybe a little bigger not by much.

 

The new Mustangs have a 15.2 gal tank.

 

wait its 25 gallons...for some reason i always thought it was 12, thats what the gas pump goes to when i fill up from an empty tank, or my fuel sender is messed up and i refill at half-tank....

 

I know it ain't a 25 gallon tank, more like 15.5 gallons if memory serves me right.
