So I dug in. Cleaned out all the little screen filters that were filthy. One in the lift pump, one in the injection pump. Like I said, I already put in a new fuel canister filter. Took out the separator unit and it was full of crud. Cleaned that all out. I went and got a Gerry can of fuel and a in line filter. Hooked that straight to the lift pump to eliminate the fuel tank. Primed the whole system and seemed to be getting good flow to the injectors.
Couple tries, she fired right up and ran for a minute. Shut down...
Primed it again. Started up, tried to throttle up, it dies.
The lift pump primer lever is not pushing the fuel past the injector pump very well. If you turn it over, it is better.
So just on a hunch, I took an electric pump I had laying about and primed it with that. Fired right up. Ran ok but would not go full throttle very long and then die.
Like I have enough fuel for just a little run, but then starves.
I am betting the lift pump.
