    1990ish Evinrude 6hp not idling

    I agree a new top is best of course but just for a trial, seeing this a hairline crack it should soak a touch of crazy glue . a top layer of Bondic should do the rest. Bondic is pretty amazing stuff and sets up hard in 3 seconds using the provided UV lamp. ..just like dental repairs.

    When do you replace the fuel filter?

    I think the filter is porous metal so it won't deteriorate much a good cleaning or two should do you can always remove it and install an in-line filter on the incoming fuel line (easier to maintain, and you can see if crud made it's way in from the tank
