Stumbles off and on...

[Geff McCarthy]

my 63 400 Eddie 4bbl usually runs well. On return from a 727 rebuild, it now intermittently acts as if running out of gas, then recovers. Yes, I need to get in there and try to diagnose, but...expertise wanted!!

Fuel filter?
Sending unit pickup sock?

Is it a flat spot? More info needed. Might be a worn/defective acc pump plunger. Actuate the pump & look for a fuel stream.

Check the pickup / suction side of the fuel system for cracked fuel line hose where it could be sucking in air. Had a cracked rubber line at the tank pickup that took me a long time to figure out.

Fuel gauge is also inop, but I removed the dash. Thanks for suggestions!!
