I am wondering if there is a chance that is not your original 40 Gal fuel tank?
Try measuring it and calculate the total capacity. Minus the air space you can’t fill up to the top.

So, guess I’ll take a shot at replacing it and seeing if that solves the problem. Anyone replace the fuel lift pump on a Yanmar 3HM35F? I am wondering if the arm that rides the cam is above the at recast engine oil level. thx Tom Buscaglia S/V Alera 1990 C&C 37+/40 Vashon WA P 206.463.9200 C 305.409.3660
