Unfortunately, I don't believe that this type of fuel pump can be rebuilt like the earlier pumps found on 216-261 engines. The one that I took off and the replacement pumps are crimped together, no screws. There may be some 'speed shop' pumps with screws but again, no guarantee about the psi output. It is not the quality of the pump that I have a problem with, but the specs that are used for building. My suspicion is that the builders looked at the specifications (psi output) for a number of pumps, chose the biggest as the best, called it good and used it for everything.
