Pump did not work so we pulled out of the tank and removed the very dirty filter. Reinstalled with out filter, (we broke it) it started working and it idled for about 10 minutes then quit. The tank was full, there is power to the pump. Any ideas short of replacing pump?
Those pumps are real expensive, but they rarely fail also.
If the filter inside the pump was that dirty, you need to take the fuel tank out to flush it and get a clean tank before you spend any more money. And do not use it without that filter at all, to prevent damage to the pump.
Can you "hear" the pump running for the 1st 5 seconds or so when you turn the switch on?
The connector on top could possibly be the problem vs. the pump.
The pump also has a fuse.
If you are now aware, the 445 works similar to a diesel, in that you are supposed to turn the switch on and wait for the light to go off.
This runs the pump to build up pressure for the injector to start.
And the main fuel filter is under the main shell on the right side of the frame between your legs. I bet it needs replacing.
Update: I just noticed the 455, vs. 445. My bad. The 445 is gas. The pump setup may be similar, but I'm not sure where the filter is on the diesel.
