The regulator is definitely seeing good vacuum, so reason to believe that line has an issue, I’ve inspected it, looks fine. As far fuel lines, that’s next on the list. I will look into that tester just because that’s great to have on hand. But I do not think vacuum leaks is the issue at this point.You tested the regulator and it works , but is the regulator seeing the boost pressure ? Are any lines pinched restricting fuel flow ? Check the relay in the hotwire circuit ( burned contacts inside ) . ALL electrical connections front to rear .
I use this intake pressure tester for finding vacuum / boost leaks .
If that's Don Cruze call him and get the right parts.Chuck,
I don’t know the PN, and I would agree it’s not the correct version, it was recommended to me by a long time reputable Buick shop. I won’t name drop that just yet as I have to get them on the phone to discuss this issue. I am still working replacing all cracked vacuum lines, but I’m leaning toward thinking it’s a pickup issue, easy enough to test by adding another 5 gallons and testing acceleration. Doing that tomorrow and will post results.
Lol Chuck, no we have never discussed this before, I got aeromotive on the phone and determined this is a gen II Buick GN setup, and if you look on their website, sure enough it’s ventless when you zoom in (no clue why anyone thought ventless was a good idea). PN 18449. Tank is down and troubleshooting pump right now. I don’t think it’s a venting issue anymore, with the cap off the car and emptying the tank via Hotwire, flow seems awfully low. Good ground, and 12+ volts coming from the harness. Pump coming out soon for inspection.Next up get the right damned parts!
But yes we did. I posted the correct pump assy pic in post 8, and you posted the wrong one in post 10.ol Chuck, no we have never discussed this before,
You've found the cause. The shitty gas we get is a major factor in the foam degrading to mush.after 4 years and only 10 hours of use
I will take you up on that offer, I may be driving down to Covington on Saturday, I can drop them off if you like?You've found the cause. The shitty gas we get is a major factor in the foam degrading to mush.
Many small engine mfgrs say 30 days and the gas is fast failing. Some won't even consider warranty.
If you want, send me your injs and I'll see what they have in them.
