It delivers fuel pressure of 5.25 to 6.5 PSI and uses a dual diaphragm design that requires a sight glass for proper operation and fuel monitoring (sight glass not included). The pump features a flange with I.D. #41414 and a 1\/4 inch-18 NPT threaded outlet connection for a secure fit into the fuel delivery line.\u003c\/p\u003e\u003cp\u003eConstructed with a cast iron body, the 18-7267 is built to withstand the demands of a marine engine compartment, resisting corrosion and heat while maintaining consistent fuel delivery. It is a direct functional replacement for the original equipment fuel pump on applicable GM V-8 marine engines, restoring proper fuel pressure and diaphragm integrity when the factory pump fails or wears out. Cross-reference equivalents include GLM 77040, Mallory 9-35411, Mercruiser 62092, 62092T, 54552, and OMC 982063, making it straightforward to identify as a replacement even when working from a different part number.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e
