IDI Engine / Re: Need help with tracking down air leak in 1.9 AAZ pump
« Last post by Buji88 on Today at 10:13:28 am »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.
