This sounds like a flow test has been done. If in fact this is a flow test and it tested good and as long as you realize it should pump right away and pretty forcefully, NOT tiny squirts or dribble, then you have a carburetor problem (if I trust your electrical check.) Best check is at plug gap. If it does not squirt properly then a different proceedure is next. I understand it is a new pump. A TF tank is vented to the cap and cap needs to be a vented type cap. If fuel flows in a flow test, you don't have any problems with fuel delivery to carb. Now I'm being a smart arse.
Fuel getting to Carb? Eventually- yes; we disconnected the carb fuel inlet & finally got some fuel to come out it a bottle. I would estimate the amount of fuel that came out was appropriate for the 'new' 4149 fuel pump's pressure rating.
