Fuel Line Plumbing and Water Seperating Filters
 

I've got the engines out of boat and am re-rigging the engine compartment. There are water/fuel seperating filters on bulkhead for ewach engine and there is a similar filter on each engine as part of EFI system.

Are the exter filters causing a reduction in fuel flow? Is the filter on engine adequite for fuel/water problem?

Would love to get rid of the filters on bulkhead since they are from the previous engine installation. Would appreciate any comments--

What type of engine? Mercruiser does not recommend adding extra filters to the fuel system. It messes with the ECM.

The engines are MarinePower EFI 454 with Arizona Speed induction and ECU.

I was guessing the filters on bulkhead filters (which reamined from Mercruiser 370 TRS carb engines) needed to go and rely only on engine mounted water/fuel seprating filter.

Would appreciate confirmation.
