Trooper Jeff -

I believe that you have the correct pump for your 55.1 truck. The pump was changed in the early 50's as Carl noted, but it was used on trucks too. Don't know when the switch from glass-top to metal-top was made. I don't know of anyone that supplies a line with the correct bend for pumps with the 20-deg angled ports. I bent the pump-to-carb line for my '54. Was pretty easy. I left the old mangled tank-to-pump line on the truck. May bend a new one someday.

FYI - GM supplied a 20-deg fitting to adapt the new pump for older trucks.
