Reinstalling the gas tank from how the previous owner disassembled to clean the tank. The truck finally runs again! Stay tuned and subscribe for more updates on the truck as well as the other projects on the channel!
Did you figure out and fix the brake issue? I have a 75 Cargostar 1710B with the same brake problem you were having. The pedal will build pressure after 4 pumps of the pedal but goes back down to the floor.
Dang. I've tried searching for a new hydroboost booster and those seem to be hard to come by... Let me know if you are able to find one (I am assuming I have the same problem!)
