Fuel Problem

[genesis08]

Is there anybody on the site that has an Inline six on their boat?I used to have like an external fuel pump with a filter in it installed.it was Electric.I removed it but I think I should not have as I believe the engine is been a bit starved for fuel.To discribeb it,its about 5"tall,2" Diameter made of brass,inlet,outlet and 2 wires on it.

Thanks for the help,

Brian....
