[QUOTE="bobbie-g, post: 56856, member: 26"] PhilNGruvy, First I thought the Pug engines were only used somewhere around '95 and '96 for two years. If you call Melroe with your S/N they can tell you the year of mfg, not that it really matters. I have a '95 751 with the Pug engine. I had to replace the fuel injector pump, $1350 for the pump from Bobcat. I should have had it rebuilt for half that. The lift pump is integral in the injector pump housing. When mine went bad (lift pump only), it would run with someone squeezing the primer bulb continuously to get fuel up to the pump. The primer bulb should be right below the fuel filter, in the line that feeds the filter. --- To see if you're getting fuel, you should be able to crack the 17mm nuts loose right at the cylinders on each of the 4 lines. Fuel should squirt out around each of the nuts when you spin the engine. To flush out all the water, etc, you could remove all 4 lines and blow them out, then spin it and let fuel squirt out the pump all over the place until the fuel is clean. --- I sure don't know, but I would just guess that all of the injectors didn't clog all at once.
