Sierra 18-7281 Marine Fuel Pump with Mounting Gasket - Replaces Volvo 826493 for GM V-8 305/350 CID Stern Drives

The Sierra 18-7281 is a mechanical marine fuel pump built to deliver reliable fuel supply on Volvo Penta stern drive applications powered by GM V-8 305 and 350 CID engine blocks. It is engineered as a direct replacement for the original equipment pump, matching factory performance so the engine gets the fuel delivery it was designed around. The pump body is constructed of stainless steel for corrosion resistance in the marine environment, and it uses screw-type connections on both the inlet and outlet fittings for a secure, leak-resistant hookup.

Each 18-7281 pump ships with its mounting gasket included, so there is no need to source a separate gasket for a standard installation. Sierra builds this pump to meet or exceed the specifications of the original equipment part it replaces, and Sierra supplies OEM engine manufacturers and boat builders with parts to the same standard every day. This makes the 18-7281 a straightforward, drop-in replacement for boaters running a Volvo Penta stern drive on a GM V-8 305 or 350 CID block whose original fuel pump has worn out or failed.
