Fuel pump turbulence 8BA

[Fairlane514]

8BA with sediment bowl and mechanical fuel pump.

I noticed when running, there is turbulence in the sediment bowl. Seems like that's not right.

Also had to prime carburetor to get it to start only after about 4-5 days.

Rebuilt Holley 94, runs fine after priming.

Not sure how old the pump is, looks pretty clean from the outside, but may need a diaphragm.
