I recently bought a 1974 F250 with a 1st generation cummins 12 valve. I broke down a mile from the shop on a weekend. I got a hold of Robert who told me I could have it towed and dropped off and they would get to it Monday. They got back to me on Monday and let me know it was the lift pump. In addition the fuel sending unit was broken. This truck is a bit of a Frankenstein and they had to figure out what would work and make it work which they did. They even stayed late to finish up on the day I picked the truck up. What a great shop! I would highly recommend especially if you have an older truck that does not have a computer to tell you what is wrong. Given the age of the of the truck I am sure I will be back. Thanks for all the help guys!!!! -Jim
