It is engineered to Sierra's standard for withstanding the harsh marine operating environment while meeting or exceeding the performance of the original equipment part it replaces. The pump is constructed of metal for durability under continuous engine-bay heat and vibration, and it mounts to the engine block using a flange mount with a hose barb inlet and barb outlet connection, matching the original fuel line routing. A mounting gasket is included, so the pump is ready to install without sourcing a separate gasket kit.\u003c\/p\u003e\u003cp\u003eThe 18-7283 fits specific Mercruiser stern drive applications by model and serial number: the 260\/5.7L GM (IB) at serial number 5907058 and up, the 5.7L-GM at serial number F025000 and up, and the 300MR\/TRS GM 350\/V-8 built in 1985-1986. It is designed as a direct equivalent for the GM V-8 305 and 350 CID engine family used across these applications, and it cross-references to the OEM numbers 6668677 and B430367.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Sierra\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 18-7283\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e GM V-8 (305 \u0026amp; 350 CID) engines\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEngine Applications:\u003c\/strong\u003e 260\/5.7L GM (IB) serial 5907058 \u0026amp; up; 5.7L-GM serial F025000 \u0026amp; up; 300MR\/TRS GM 350\/V-8 (1985-1986)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlange I.D.:\u003c\/strong\u003e M60600\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Metal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Type:\u003c\/strong\u003e Flange Mount\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInlet Connection Type:\u003c\/strong\u003e Hose Barb\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutlet Connection Type:\u003c\/strong\u003e Barb\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes:\u003c\/strong\u003e Mounting gasket\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Dimensions:\u003c\/strong\u003e 5.75 x 4.5 x 4.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 1.74 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 030999322548\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e260\/5.7L GM (IB), serial number 5907058 and up\u003c\/li\u003e\n\u003cli\u003e5.7L-GM, serial number F025000 and up\u003c\/li\u003e\n\u003cli\u003e300MR\/TRS GM 350\/V-8, 1985-1986\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e6668677\u003c\/li\u003e\n\u003cli\u003eB430367\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat engines does the Sierra 18-7283 fuel pump fit?\u003c\/strong\u003e The Sierra 18-7283 fits GM V-8 305 and 350 CID Mercruiser stern drive engines, specifically the 260\/5.7L GM (IB) from serial number 5907058 and up, the 5.7L-GM from serial number F025000 and up, and the 300MR\/TRS GM 350\/V-8 built in 1985-1986.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhich OEM part numbers does this fuel pump replace?\u003c\/strong\u003e The 18-7283 cross-references to OEM numbers 6668677 and B430367 for the covered Mercruiser 300MR\/TRS GM 350\/V-8 application.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is the Sierra 18-7283 fuel pump made of?\u003c\/strong\u003e This fuel pump is made of metal, chosen for durability in the heat and vibration of a marine engine bay.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 18-7283 fuel pump include a mounting gasket?\u003c\/strong\u003e Yes, a mounting gasket is included with the Sierra 18-7283 fuel pump so it can be installed without buying a separate gasket.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the connection types on the Sierra 18-7283?\u003c\/strong\u003e The 18-7283 uses a hose barb inlet connection and a barb outlet connection, with a flange mount for attaching to the engine block.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the flange size on this fuel pump?\u003c\/strong\u003e The Sierra 18-7283 has a flange I.D.
