IDI Engine / Re: Need help with tracking down air leak in 1.9 AAZ pump

This one has me confused too.
 I know when it's not pulling fuel the accelerator doesn't increase RPMs.

 Did you try swapping a regular/input banjo bolt in place of the "OUT" banjo bolt?
Just to see if it's pumping fuel through the pump and maybe see if the OUT bolt restrictor hole is clogged.

What a crazy bunch of weirdness.  Glad it is on your ride.

Got it sucking fuel last by itself, and it looks good in that regard.

I kind of got it running last night, but only on one cylinder #3 was getting plenty of fuel. With glow plugs its actually fairly stable, shut them off it will slowly stall. but Im not sure why that is happening. The other cylinders seem to be getting a dribble compared to 3 which actually squirts. So I'm guessing there is a massive air bubble in the pump. Going to pull all the lines and start bleeding directly out of the delivery valves and work out from there.

I also have no throttle control, pulling on the lever does nothing for engine speed at all, but Im assuming that could be related to the issue that 3 is only getting adequate fuel/pressure.

Weirdly, it starts pretty easy, considering only one cylinder seems to be functioning.

Have you tried swapping a regular banjo bolt for the regular banjo bolt?
 10 should be enough vacuum to pull fuel through the pump.
 If it isn't, the OUT bolt might be plugged.

 If it pulls fuel with a regular/unrestricted banjo but not with the OUT bolt then that's part of the problem.

Well the saga continues. Got it all back together and on last night, but now there is no output of the pump from the delivery valves and you can see nothing is getting pushed out the return line.

I tried priming the pump with my hand vac initially and it led to this question. Is 10 inch of vacuum to much to get fuel flowing (hand vac pump on the fuel outlet)? That feels pretty high feeding from the tank. It also holds that vacuum easily. I am starting to wonder if my filter is plugged since before all this happened, I drained a lot of fuel out of the tank by mistake, and it seems like it progressed slowly from that point.

 Good, glad someone can use it.
I have a pretty good collection myself, but even then somehow this ad puts me at ease.
 That I'm not the only one and there are other stashes out there.
Not another one of those hard to find parts quite yet, if you know where to look.

 Real common to find a rabbit with these missing or partially there.
 I should do a walk-around of my buddy's rabbit, see if any are missing

Don't need em though, so if others do let me know.  I already can tell you that the one with the bump on it is gone.  One of the members here has claimed it.

These are what I have on hand in the shed.  Looks like a couple of pairs of regular ones and a mismatched set of the raised rubber bumper and the other style.

Got the new account working for these parts.  What a royal pain in the patootie.

I saw a guy on Marketplace that had a ton of starters.  If I can find that again I will link to it and you can contact him directly.
