Sounds like this pump only gets to 3 psi

If you're not using a bypassing regulator you old electric pump probably overheated then pressures go down.

For a carburetor of factory TBI, I like to run either a high capacity in tank low pressure (15-20 psi) TBI pump or a pair of standard Low Pressure TBI pumps in parallel with a bypassing regulator back to the tank. This insures plenty of cool fuel with a steady pressure at the carb regardless of engine consumption.
