Installation Notes and Quality

Verify the application notes before installation, including the crankshaft sensor note listed for the fitment. Confirm gasket and sealing surfaces are clean and inspect the pump drive interface before assembly. The M186 includes a gasket or seal, but no bolts, drive shaft, or pickup screen are listed as included. Melling tests each pump for pressure and flow to confirm operation under conditions that duplicate engine use.
