Have a 07 660 with 1800 miles. Long story short ive had it 6 months, its just used around the our house and is our plow for the winter. It started to overheat so I put in a new radiator and decided to also pull the carb at the same time to give it a cleaning. Did so, put it all back together and now no start just cranks. Checked fuel filter, checked spark, all good. I tried cranking quite a bit and holding my hand over intake but still no start. Pulled inlet line to carb and filled it with gas and she fired right up run till line dries up. If the system wont prime should I assume my fuel pump is dead?

I was reading that on another thread. For what its worth I filled the line from tank with fuel and filled the line from the T/Y at the pump with fuel and reconnected. It starts but wont siphon fuel from tank and apparently wont prime. the vacuum style pumps wont clear the air even after a decent amount of cranking and idling for 10 minutes? Never owned a boat but i get the bulb method but is that going to work given what I've tried? I checked my fuel lines again to make sure they were all snug and had no cracks. Like i said it ran fine prier to removing the carb.

Appreciate the help

Here's some thoughts:


Given that it runs okay till fuel in the line is exhausted leads me to think the carb is okay. Have you tried removing the fuel line at the tank to check gravity fuel flow? If non, remove fill cap - if that helps then replace cap. If still no good, clear tank obstruction and/or fuel on-off valve.


If fuel supply from tank is good, then check for fuel at pump inlet - if not good replace (collapsed) fuel line/hose). If you have good fuel delivery to inlet side of pump but nothing out other side then obviously replace the pump. You stated fuel filter is good? Can you blow through it okay?

Okay. So it was running before you "fixed" it. Are you certain you connected the fuel lines properly? Unless it set for a long period of time I can't imagine the fuel pump failing between the last time it ran and now. Here is how to test the fuel pump operation.

Good to hear. Did you source the primer bulb from the military surplus site? Curious to know if there products are good enough to recommend.
