I won't give a blow-by-blow description of our chasing around auto parts stores -- it's too depressing -- but eventually we got all of the other parts Lisa wanted to try. She replaced two fuel filter assemblies. Both of them were full of junk, including ants of all things! There was some hope that maybe it was just clogged fuel filters. But when we took the van out for a test spin, as soon as it needed significant power to climb a hill, it starved of fuel. The auxiliary electric boost pump can help, but it's not enough to keep the van at full power. Lisa says that means it's almost certainly the fuel pump.
Because of the day's delay getting the pump, she'll be here until Sunday now.
Spending a day driving hither and yon for auto parts is not fun. Throw in the fact that Lisa is still fighting a sinus infection and is feeling pretty sick while she's still trying to work on her van, and you have a recipe for high stress and unhappy times. And inefficiency: we ended up going to Rite-Aid three times today on account of remembering three different sets of things (some medicinal, some not) that we needed.
Thank goodness that the worst of the hot weather broke and that the evenings have been cool, because the air conditioning in this room isn't working. The heat pump makes noise, but no air moves through the vents. We'll call this to the management's attention in the morning.
