Shut the tank, relieve pressure, catch fuel. Photograph the pulse hose versus fuel inlet and outlet. Remove the flange screws, keep the old gasket for the pulse-hole layout, and clean the pad. Seat the new gasket so the pulse passage lines up — 180° off looks like a dead pump. Snug evenly. Prime, leak-check at idle in the slip before you load the boat. If it still will not pick up fuel, check the tank vent and primer before you blame the new pump.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWill this fit my Volvo Penta AQ131 \/ AQ151?\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eAQ131A–D and AQ151A–C rows are on this table with 841161.
