My suggestion is to swap out the carb with the other one you have. That way you’ll know if your original thought of replacing the fuel pump is warranted.
Mikko,
Good looking 53. Actually, that year Ford was the first Ford I ever rode in. A few years later my family bought a 57 convertible with a 312 automatic and a Town and Country radio.
