I would like to share some pictures of my truck. I have decided to keep this truck as it was built, a fire truck. At first I was upset with the modifications not being done in a neat manner . So I began to remove the pump and the associated equipment, I am in the process of putting it back together and I am going to try to do a better job. I was able to locate an instruction and installation manual for the Barton front pump. Here are some of the specs on the truck
1950 chevy 6400
10,500 original miles
235 low pressure 6 cyl
4 spd with 2spd rear
barton American 500 gpm front mount pump
