Well Saturday is here, time to rebuild my fuel pump on my outboard. Everything out of the way, pump is off, disassemble, start rebuild, comes to a halt, one of the rubber diaphragms has 2 pin holes in it, of course I am told to call Sierra, if they say its bad then to call iboats and return for replacement. For a 12.00 kit, think not, waste of time ordered new one from someone else
