Hard to get the fuel filter out, with hard lines on both sides, inverted flare fittings and a stiff, stupid, encircling bracket.

The check valve of the fuel pump is apparently broken and the pickup in the tank is above the filter, so a gallon of gasoline siphoned while we were trying to get the filter out, down our hands and arms, into a bus tub. Stings. Stinks.

New filter is an inch longer than the old one: no way it can work, so we put the old one back to stop the flow, and bailed out.

New new filter is the right length, but the female fittings on the filter are aluminum, and the flare nuts are brass. That'll be a problem later, for sure.

Found the vent line for the tank and stuck a cork in it to staunch the siphon, and got the new filter in place AND figured out the trick for getting the bracket back on.

Reattached the PCV line that had pulled off of the air intake, far downstream of the mass airflow sensor. That would certainly cause a P1074, which has not recurred.
