I had a '49 Chevy (around 1962)& I needed to replace the fuel pump. Bought a rebuilt one from Napa. Ran fine up top ~50 mph & it would bog down. Get below 50 and all was well (unless trying to accelerate. Checked everything I could think of (e.g. filter, etc). The cure another rebuilt pump.

On another Chevy (1971) would bog down at ~ 35 mph. Turned out to be a plugged exhaust system.
