Im putting a tbi motor in a 84 k10. Ive got questions about gas tanks. Ive read in a few places about getting 87 model tanks. Did the 87 models come with 16 gallon tanks, 20 gallon tanks or both Did the 16 gallon tanks have a baffle for the pump? Or were they just like the carb model tanks? If yes does anyone have a picture of the inside of the tank? If no 16 gallon tank, do the 20 gallon tanks swap right in place of 16 gallon tanks (Same brackets/location)? Thanks.
