Manual or electric fuel pump? Mercruiser 4.3

[bradt041]

Hey all. I recently replaced a 2 bbl carb and intake with the edelbrock performer series 4bbl on my 4.3l Mercruiser. I have had it out 3 times and it did well. The other day I filled up the tank (it puked out the vent on the side of the boat) and when I took it out that day it surged on me quite a bit, but only after a few minutes of 3/4 throttle. I noticed the fuel filter was about empty (it's see through), but after I would throttle down it would fill back up. Could this be a venting issue in the tank? Or do I need to go with a electric pump? It does have a newer holley manual pump on her now.

Thanks for the advice

This was posted awhile ago, I will give my 2 sense worth anyways. I have a 2008 4.3 with a electric fuel pump.
