For: All MerCruiser MPI, EFI, and TBI models with Cool Fuel MerCruiser Serial #0K999999 & Lower

Note: Numerous engines with serial number 0K999999 and lower were affected by Service Bulletin 1997‑20. Repairs done under this bulletin resulted in a change in the fuel lines and a change in the cooler to the cross‑bolt style fuel line attachment. To determine the correct fuel pump and cooler kit on these engines it will be necessary to determine the method of retaining the fuel line on the cooler. If the cooler is original and the fuel line is retained by a bolt on a fuel line flange, use kit 861156A04. If the fuel cooler was replaced and the fuel line is retained by a fuel line retainer screw (cross bolt style), use kit 861156A02.
