Boy, I have never tried it, but I don’t think those larger pumps will mount on the original location on the starboard side of the powerhead…The larger pumps are usually located on the port side of the engine, then the pulse line runs from the pump over to the stbd side where the original pump was located….
93 and later models had the larger pump mounted on the port side, and it mounted right to the block….
The big pump change was precipitated by those "accumix" tanks which put an additional load on the fuel pump….
The 438562 number you mention is for the 93 and newer models and will mount directly to the port side of the crankcase on those engines…But, I don’t think it will mount/fit on the starboard side of the older models, even though the bolt pattern/gasket is the same….The part number I found for the pump you would need is: 438500 you will see the bracket in the enclosed link…
