Re: 1989 Hunter 40 - A million questions.
The picture looks to be the fuel level sender - it should have a single ground wire headed back to the gauge -
I agree with Seaduction - if the leak only occurs when the engine is running it should be the fuel return - it matches all of your symptoms - check or replace the line - even if it was fine on the sea trial, if it was not recently replaced (and in some cases even if it was) it is a pressurized line, likely has swedged fittings at each end - although I have seen them with just hose clamps - I've also seen a hose clamp over tightens to the point where it cut through a fuel line and leaked over time little by little until it finally failed -
