During installation I noticed that the suction power wasn't as good as the original. I tried to figure out why and found that the replacement didn't come with a rubber gasket to seal the connection to the block. I tried to use the old one, but since it's too old, it can't be reused. I wish he had mentioned that when you bought the device. Now I have to order a rubber gasket to make this thing work and I'm hoping I order the right one.
