It would be nice if the kit included some installation guidance, or at least an exploded parts diagram.

Full StarFull StarFull StarEmpty StarEmpty Starlooks like OEM.but slightly out
by Douglas from Howden, Manitoba on May 18, 2011
replaced this kit in place of the original.Found out the manufacturer didn't machine the tube opening deep enough to allow for water tube fron on top to drop into.Couldn't get my bottom unit bolted on,there was a gap of about 1/8 inch between bottom unit and upper.I had to drill with a flat bit 1/8 deeper into the pump upper tube housing.This wasn't a big thing to doas long as you have the right bit,otherwise one could force tighten the units together and probably crack the pump housing.Otherwise after this mod,everything went back together and pumps works good.

Q:
Can you sell 18-3447 without the housing?
A:
Unfortunately we cannot as we take OEM numbers and cross reference them. The OEM number for your Merc cross references with housing included.
