i have an '81 k5 4x4, and i have installed a 5.7l fi engine out of a 94 c1500. i am now trying to figure out which way to go for the fuel pump. what year k5 came with fuel injection? i assume they had an in-tank pump. would that be a bolt in swap, or did they change the tanks. any info will be helpful.
