Ok wait a sec....
If you had the carb rebuilt what was the reason?
....car would run but not idle or has the car been sitting for a LONG time ?
If the car runs with you manually adding fuel... Well then it's behind the filter....
I ASSUME the car is stock and not a restro mod....
I would disconnect the line out of the pump...behind the filter gat a hose on it, grab a mason jar , coke bottle some small container and see when you crank it
if fuel comes out...
If your fuel pump is semi original, the rubber in there doesn't deal well with today's fuel formulations..
ALSO
Take a look at your oil level and smell the dip stick.. does it SMELL like fuel.. is the oil level high?
When the diaphram in the pump leaks... gas can get into the oil pan, diluting the oil... Not so good!
If that all seems OK, ( no fuel in oil, but no gas coming out of the pump ) ...
Rig an aux fuel supply going into the pump... does it pump now?
If not, replace the pump..
This all assumes you have proper facilities and KNOW how to turn a wrench PLUS work with exposed fuel and fuel vapors.
