Caution!!!! Not all bulbs are created equal. Earlier in this thread you will see I had the same problem and didn't want to wait a month and the WagAero unit was cheaper but uncertified, well I learned something. There are two styles of bulb. My original had a tapered shoulder on the ring to seal it against the screen housing. The WA bulb has a square shoulder on the sealing ring. Guess what happens after a few hours. It cuts a groove into the mating tapered seat and comes loose and leaks. Fortunaly it was in an adapter in the spin on filter adapter and not in a screen housing which are mega bucks. So after wasting $300 at WA, now I sent the original unit and bulb down to Lock Haven for a $436.91 repair to put my old bulb on a new tube. I didn't even get a new faceplate. The 2 week turnaround took 4 and when I called after 2 they said they were waiting for it to come back from where THEY sent it. I'll try to post some pics of the 2 bulbs.
