It mounts on the fuel cooler and regulates fuel pressure delivered to the multi-port fuel injection system, holding the fuel rail at the pressure the engine's MPI system needs to meter fuel correctly. The regulator body is constructed of metal for durability in the engine bay environment. This part directly replaces OEM number 860349A1, so it installs in place of the original regulator without modification. Sierra manufactures this component to original equipment specification, making it a straightforward, correctly-fitting replacement for a worn or failing fuel pressure regulator on these Mercruiser MPI engines. Because fuel pressure regulation affects air\/fuel ratio, engine performance, and emissions, replacing a weak or leaking regulator with this unit restores proper fuel delivery. It is compact, measuring 0.39 x 0.39 x 0.39 inches, and weighs 0.12 pounds.\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 18-33207\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Mercruiser Fuel Pressure Regulators\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReplaces (OEM):\u003c\/strong\u003e 860349A1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitment:\u003c\/strong\u003e MCM\/MIE 7.4L\/LX MPI, 4545 Mag MPI, 502 Mag MPI, MIE 8.2L MPI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Location:\u003c\/strong\u003e Fuel Cooler\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Metal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Dimensions:\u003c\/strong\u003e 0.39 x 0.39 x 0.39 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.12 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282341695\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMercruiser MCM\/MIE 7.4L\/LX MPI\u003c\/li\u003e\n\u003cli\u003eMercruiser 4545 Mag MPI\u003c\/li\u003e\n\u003cli\u003eMercruiser 502 Mag MPI\u003c\/li\u003e\n\u003cli\u003eMercruiser MIE 8.2L MPI\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e860349A1\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-33207 fuel pressure regulator fit?\u003c\/strong\u003e The Sierra 18-33207 fits Mercruiser MCM\/MIE 7.4L\/LX MPI, 4545 Mag MPI, 502 Mag MPI, and MIE 8.2L MPI engines, and mounts on the fuel cooler.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat OEM part number does 18-33207 replace?\u003c\/strong\u003e Sierra 18-33207 replaces OEM number 860349A1, so it can be installed as a direct substitute on applicable Mercruiser MPI engines.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhere does this fuel pressure regulator mount?\u003c\/strong\u003e It mounts directly on the fuel cooler on the applicable Mercruiser MCM\/MIE MPI engines.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is the Sierra 18-33207 made of?\u003c\/strong\u003e This fuel pressure regulator has a metal construction, matching original equipment build quality for these Mercruiser fuel systems.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-33207 fuel pressure regulator weigh?\u003c\/strong\u003e It weighs 0.12 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the dimensions of the Sierra 18-33207?\u003c\/strong\u003e The regulator measures 0.39 x 0.39 x 0.39 inches.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-33207 a genuine Mercruiser part or aftermarket?\u003c\/strong\u003e It is a Sierra-manufactured fuel pressure regulator built to original equipment specification, offered as a replacement for OEM number 860349A1 rather than a Mercruiser-branded part.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes 18-33207 fit the Mercruiser 502 Mag MPI?\u003c\/strong\u003e Yes, the Sierra 18-33207 fuel pressure regulator is listed as fitting the Mercruiser 502 Mag MPI engine.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill this regulator work on a Mercruiser 4545 Mag MPI engine?\u003c\/strong\u003e Yes, Sierra part 18-33207 fits the Mercruiser 4545 Mag MPI, along with the MCM\/MIE 7.4L\/LX MPI and MIE 8.2L MPI engines.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is included when you order the 18-33207?\u003c\/strong\u003e The order includes one Sierra 18-33207 fuel pressure regulator, ready to mount on the fuel cooler of the applicable Mercruiser MPI engine.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy would I need to replace my fuel pressure regulator?\u003c\/strong\u003e A failing fuel pressure regulator can cause incorrect fuel delivery to an MPI engine; the Sierra 18-33207 replaces OEM part 860349A1 to restore correct fuel pressure on applicable Mercruiser engines.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988143976667,"sku":"SIE-18-33207","price":212.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/18-33207__45627.1722498962.500.750.jpg?v=1785188558","url":"https:\/\/www.goodvibesmarina.com\/products\/fuel-pressure-regulator-for-mercruiser-7-4l-454-502-mag-mpi-8-2l-mpi-replaces-860349a1-sierra-18-33207","provider":"Good Vibes Marina","version":"1.0","type":"link"}
