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.
