I went down to Florida this weekend, and was within 80 miles or so of BogieRudy, so I went over to his place.
Bogie left our GTG with his car dying periodically do to fuel starvation. It was a plugged 'C' model fuel pickup assembly. The check valve in the fuel outlet line was plugged with junk.
We changed him out to a spare 'D' model assembly that someone had left in the shop a year or two ago when they installed a lift pump into their ALH. This one still has the check valve, but the valve was not plugged. Bogie knows to drill it out if he has any issues (I did not have time to drill it out before I left for Florida). His car was running much better.
I chastised him for leaving without us fixing his car. It took him 12 hours to do a normally 8 hour drive home.
He still has a sticky turbo (overboosts) but this may burn itself free, now that it can get some fuel. If not we can clean the turbo some day. At least it will run without having to pull over to let the fuel filter slowly refill.
