Tank level probes
(Hopefully this answers David Brady's question, although I would not be
surprised if it was completely different in '02) The "sensors" are the stainless machine screws themselves. They are installed in pairs, so one grommet per screw, two per "sensor." The screws were in good shape. The two I started with were the "Full" sensors, so I may find things worse when I get to the 1/4 ones near the bottom. If so, there is nothing odd about them and any well-stocked hardware store should be able to supply them. I was surprised to find that the captive nuts are brass. At this point it occurred to me that pictures would help: http://www.arcatapet.net/travel/images/9...ensors.jpg http://www.arcatapet.net/travel/images/9...ensors.jpg Don Bradner 90 PT40 "Blue Thunder" Eureka, CA On 6/5/2007 at 3:17 PM Leroy Eckert wrote: >Mine is the same year.
