The cast iron housing, precision-ground cover, and powdered metal rotor support stable performance, while the close-tolerance gear and gerotor design helps maintain proper engine pressure and efficient pump operation. This pump is a practical choice for stock-style service on Mazda Protege, Mazda Miata, Ford Escort, Mercury Tracer, and related applications listed in the fitment data.\u003c\/p\u003e\u003cp\u003eThe M191 is also built with a rust preventative finish and a five-hole mounting pattern. It is listed with a 16.00 mm inlet size, a 0.630 in pickup tube diameter, and standard pressure\/standard volume specifications. This part cross-references Monroe Shocks \u0026amp; Struts (e.g., 172286, 182286) for the same application.\u003c\/p\u003e\u003ch2\u003eWhat It Helps Address\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eLow or inconsistent engine oil pressure\u003c\/li\u003e\n\u003cli\u003eReduced oil circulation in a worn pump assembly\u003c\/li\u003e\n\u003cli\u003eNoise or wear related to poor lubrication flow\u003c\/li\u003e\n\u003cli\u003eService replacement needs for stock engine maintenance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eVerify the casting number, mounting pattern, inlet size, and pickup tube dimensions before installation.
