On my Yanmar 18, the fuel hoses are so short that the bolts get loose every time I go out. My mechanic recommended routine tightening after every trip, using 14 mm closed-end wrench at the pump and 17 mm at the fuel pump. Sure enough, I stripped one of the bolts at the pump, requiring a major rework. My touch was not all that hard, but those aluminum threads just can't take much torque. At any rate, that's how you reduce the ceaseless drip at the pump.
