Just installed it - and replaced the PVC valve while it was out since I could reach through the intake and help spin the valve off and the new one on again.
None of the parts stores had it in stock and said they couldn't get one until Monday. Rockauto.com has them in stock and the closest warehouse is in Smyrna, TN. UPS ground from Smyrna to Knoxville is like getting overnite delivery for the price of ground (~$8) - ordered it Thursday afternoon and it was at my door Friday afternoon. I chose the Beck Arnley 110A with 1yr warranty for $125. They have another brand for as little as $110 and Bosch reman for as much as $190.
