As far as the Carter fuel pump, most likely the original pump was an AC fuel pump and replaced with the Carter during the rebuild.
Thank you very much for your knowledge and suggestions.
I will try to find a two barrel manifold and do some research on the AC fuel pump,in the meantime the motor does have the One barrel Holley that I rebuilt 30 years ago and I do have a rebuild kit for it and did finally find the Carter fuel pump and should have that in a week and it is also on the motor but it’s not functioning.
I’ve had this truck for 50 years and a anxious to get it on the road again.
Thank you very much for your knowledge and input.
