Hey guys I have a 4.3 mercruiser SN 0D814708...I need to replace my filter and in the manual it’s a fuel filter with water separation and I cannot find the replacement. The inlet side is setup for a rubber hose clamp on and the other end is threaded for the hardline that runs to the fuel pump, it’s a round style but not the spin on new ones...anyone have a replacement part number or should I redo the fuel system to a new style fuel filter/water separator? Thanks guys

The part you are talking about is 35-805031T. It is no longer available. I am not sure if it was superseded with others that may work as it is currently set up. Might make sense to just switch it over to a remote, screw on water/fuel separating filter. Something like this 35-807172A 1...

Agree, it was replaced by the lower number, and its a kit to change it to a spin on type.

Bought one thanks guys! Had to order the permatex 56521 that’s equivalent to the Loctite 565 that the instructions called for
