It replaces Mercury 881862T1, 881862T07, 892874T, 899106T and 8M0141844 and crosses to Sierra 18-8866, and it fits the 2002 and later non EFI motors in a 17.5 x 11 x 10 cm box.\u003c\/p\u003e\n\n\u003cp\u003eThis is the pump used on the carburettor four strokes, not the high pressure pump inside an EFI vapour separator. The two look nothing alike in the hand and are not interchangeable, so check the number on the old pump before ordering.\u003c\/p\u003e\n\n\u003cp\u003eThe pump body is aluminium with a rubber diaphragm driven by the camshaft, and it fails in the usual way: the diaphragm stiffens, the pump loses its stroke at high rpm and the motor leans out above 4000 rpm. A split diaphragm puts fuel into the crankcase and the oil level climbs, which is the point to stop using the motor.\u003c\/p\u003e\n\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable
