I have two evaporator cores, and each pump is connected to one of them. From the engine, the single AN16 line goes to a T to feed back to the eavp cores. Both pumps have a one way valve that prevents backflow. I could have a problem without the valves if one pump wasn't working. I could use the WP336 with the WP91 adapter, or the WP337 with the WP90 I have now. Well it's off to the airport. Bob W. (Having more trouble getting to the airport than Rusty.)
