k10 fuel tanks

[mavtricks71]

Gentlemen another question, I have a 1986 k10 Anybody know if it would be 16 or 20 gallon tanks in my truck?

 

[1987 GMC Jimmy]

It came with sixteen if it's a short wheel base or 20 if a long wheel base. You can put 16s in a LWB, but you can't squeeze the bigger ones into an SWB truck.

Makes sense it's a short bed ....so that means it's got the 16 gallon tanks.....thanks
