My A4 has been running slightly rough lately, and I'm overdue for a tune up. I'm getting the boat ready to sell, so I figured I'd get the ol' A4 purring properly.
As I removed the secondary fuel filter, the bit of stuff that dribbled out of the fuel line looked odd, so I powered the electric fuel pump and extracted a jar full. Holy crap! What came out was this murky, cloudy crap that didn't even look like gas! Heck, it didn't even smell like gas. I should have taken a picture of that jar, you'd all have been amazed that an engine can run at all on whatever this crud was!
This lead to a fuel fuel system check. Gas at the top of the tank was perfect, but my big Racor fuel filter/water separator had obviously reached it's limit. I pumped out ~5 gallons of gas using the A4 pump and each jar full looked slightly better than the last till finally I was at reasonably clean gas. Replaced the filters, did a bit of carb cleaning, and now she's running perfect again.
Anyway, this is just another example of how resilient these amazing little engines are. I can't imagine that any car engine would have been able to fire up at all on whatever it was at the bottom of my tank.
