Fuel will only come out there while cranking the engine with the throttle open. Fuel should not come out of there while pumping the primer pump.

That was my problem. The shutoff works by moving the fuel rack. Mine was stuck because one of the plungers in the injection pump was stuck. It only had a tiny bit of rust on it. Ended up replacing the pump with a new one. The comment about the gear torque being too high is right. I went with less and some red Loctite. I timed it according to the method in the manual. It took a little while, but starts and runs excellent now.

I had a friend push the start button while I watched that injector but I didn't see any movement of fluids.

Nick, if it makes you feel any better, today the (formerly) parts SEE stopped running again. The strainer had about 3/4-inch worth of "black sand" in it.
Looks like that tank has to come out, one way or another.

Here's a view inside my fuel pump. It looks like Barrel #2 is locked up, probably from rust.

That is what mine looked like. That plunger stuck will not allow the rack to open so no fuel. I was not successful at getting mine unstuck.

88FLU419 - I'm sending you a message. I have a few questions.

A this point I'd be tempted to squirt some sort of penetrant down the hole for the number two cylinder and see if it could loosen things up.
Not knowing what the innards of a pump like this looks like, it may not work at all. But that wouldn't keep me from trying.
Alright, in reality I'd look at an exploded view of the pump first, before spending time taking the line off.

i thought the same thing but no luck with mine. Injection pumps have extremely tight tolerances. No room for the smallest bit of rust on the plunger.

Also if you turn the engine over by hand you may see that more than one are stuck.

After seeing that the 50/50 acetone and ATF mix I've been using lately will seep through the seam at the bottom of a crimped oil can, I'd give it a try.
