Got the replacement cartridge into the air dryer, drained all three ping tanks and added an air chuck (brass "T" with drain valve at the bottom) to the rear ping tank, put a coiled short air hose on it so the quick connect on the end was next to the side of the bus. Hooked up the old air hose (the only one that was NOT stolen along with David's air compressor). Got all the tires filled with air except two - the flat and an inner one that I cannot reach the valve. Looking at the tires while filling makes me think I will replace them all. Maybe I can get some take offs. The truck stop is too far to take the bus with a flat on it. But I need to call the people who contract the school buses here and see if they can tell me who is the best place to go to in town for tires. The place I would have normally gone to has closed.
Still, I got the radiator hose replaced and the power steering hose replaced. I now have power steering. Driving the bus around the block and down a narrow alley so I could back the bus into the back yard was a lot easier. I was concerned that my 90lb daughter would not be able to wrangle the steering wheel and therefore unable to drive the bus. I managed to miss the power pole, the fence posts, the Class C in the driveway and the neighbour's concrete block fence.
