Help I don't know anything about this machine
If you have already changed the fuel filter then it is probably the screen in the tank. If you raise the cab and follow the fuel line into the tank there is a rubber grommet you pull out then the hose and screen will pull out so you can either clean or replace. That is what always happened with mine most times before the filter clogged.
starts and dies immediately, or? need some more info... :drinkup
Just search bobcat 763 injection pump.. lots of good diagnostic info.. a lot from me.. lol
We had a 1997 763. We would have that problem from clogged fuel filters. Till one day a filter didn't solve it. The pickup tube in the fuel tank degraded to the point it would pull fuel. We used a out board fuel tank strapped on the roof of the cab, ran a fuel line to the primer bulb to get it back home and found the rotted pickup lineafter digging into a bunch of other stuff.
