Got bested by the fuel filter. Ugh.
Got the oil changed (first synthetic oil for the car, I would bet) and then decided to do the fuel filter. Took the pressure off the line by draining at the schrader valve. Got the bolt out of the holder with shockingly little trouble. The quick disconnect on the schrader side clicked and came off with no effort. Then spent an hour trying all manner of ways to remove the other side's quick disconnect. No luck. Decided to put it back together and call it a day. Will try again some other day. Any ideas?
