Scott Krueger N92EX Scott: Try Thomas Products- http://www.thomasprod.com/flow.htm They have flow switches that open/close when fluid is flowing. I am installing these as a complicated alternative to the 2 sight tubes. I initially got the 1900 switch, 0.1 GPM flow swithc point, 1/4 NPT, SPDT, in brass (aluminum is available for "large" orders). However, it was quite heavy (1.8 lbs ? for 2), so I ordered the model: 2100 in ploysulfone (much lighter) with the adapters for NPT. I understand the polysulfone is fuel proof and think it will work fine, although I know aluminum/brass is preferable. I also have an auto. fuel transfer using the Skysport sender and 2 relays, which has been fantastic over 120 hours (drawings should be on the LML in the near future). I plan on having 2 additional red indicator lights wired to the flow switches, which would come on when the pumps are running but no fuel is flowing.
