fuel problem with my 350b crawler loader

shedd64 · Jul 3, 2015

I am new to owning a 350b crawler and am having problems with the fuel, I bought this from an older fella and it had been sitting for a few years, it ran fine for 2 or 3 hours and then started starving of fuel, i replaced the fuel filter and blew air back from the pump into the tank to remove and particles that may have caused a problem, i then removed the fuel line that feeds the injector pump and had lots of fuel coming to that point, it runs for 15-20 seconds and then dies out, can anyone tell me what else to check for that may be causing the problem? thanks

Its possible the return line elbow on top of the pump is blocked,take it off and clean it and try again.

Try running it with the two screw timing cover on the side loose allowing fuel to leak, if it keeps running then the injection pump needs serviced..

Try Replacing the copper banjo washers on the fuel line input to the injector pump. If they are a hair loose or worn, the symptoms you describe will happen. I have been down that road before.

Also make sure the electrical connection to the injector is good. You can make a jumper from Bat positive to injector connector under rubber boot. If the machine runs good than you had a bad connection.
