How do I find out what size fuel tank I have for a 1991 GMC Sierra 1500?
Fuel tank is leaking and I need to order another one. Tried using the VIN on
some sites but no luck.
There were two sizes. Measure yours to see what size you have. http://www.lmctruck.com/features/cd/CDGTK.htm
Shortbed trucks were equipped with 25 gallon tanks; longbed trucks were equipped with either a 25 gallon or 34 gallon tank. Measure your gas tank or gas tank shield to determine which gas tank you need.
