So now that I believe the raw water pump issues are resolved I also am wondering if the loud screaming sound from the low pressure pump is normal? It starts after about 10 seconds of running and after about a minute of idling the temp of the fuel pump is at 130f. The sound varies in pitch like a cycle which I assume is from it demanding fuel as the float in the fuel resevoir opens and closes? I checked both fuel pumps for any debris and found none and the fuel filter is new. Currently I have the end of the hose from the low pressure pump assembly just dropped in a 5 gallon fuel can for testing while the main tank is being refurbished. Would not having the antisiphon valve on the end cause issues or is this low pressure pump just toast. The boat sat for 2 years from previous owner neglect and gas tank had some pretty awful almost turpentine fuel in it. Wasnt sure if maybe the ethanol garbage somehow ruined the gears in the pump?
