I had a bad fuel pump on my 1989 Merc 35hp outboard S/N 0b167294. I removed it with some difficulty due to a mounting screw rubbing against the lower cowling. I thought nothing of this at the time. I rebuilt the square fuel pump without any problems, but noticing that the pump does not stay together due to the new springs, gasgets, and diaphrams. I tried every which way to get it mounted back on the engine but to no avail. Has anyone had the same problem or know how to remount it?

Thanks for any help

 

Is that a 2 piece lower cowl? If it is split them and the side will be open.
