Fuel gauge for 6 volt positive ground system

I?m having trouble locating a fuel gauge for the 240. I found the sending unit at Steiner?s. The part number I have is 371056R91.
What I?m seeing in every description is that it?s for 12v negative ground systems.
Can anybody point me in the right direction for this? This is the Rochester set up I?m looking for.

U240, From looking at my Steiner's 2018 catalog the sending units they have for sale are for 12 volt system tractors and the Farmall/International 240 is not noted as being an acceptable application for any of their listed gauges being a 6 volt positive ground tractor. I went through all of this on my Farmall 240 restoration in 2014 and found what I needed in a couple of places. If you are specifically looking for a 6 volt positive ground dash mounted fuel gauge unit I found a 371056R91 in like new condition at Bates in Indiana but had to have the sending unit custom made my an individual in Wisconsin. Also, I see Weber Tractor Parts (they advertise in Red Power Magazine) has 371056R92 (yes R92) available in their inventory for sale which should be an acceptable replacement for the R91 gauge but might be somewhat different on the faceplate or some other feature but is a Rochester gauge as well. The Farmall/International 404 uses the same fuel system items you are needing which might be an additional source of salvage or used components. My email is open if you need additional information or contact information from someone who has ploughed this furrow before please send me an email through this forum; HTH, Hal.

Thank you, Sir! I sent you an email.

Check with Jerry Trcka at EverGreen Restoration in Spooner, WI. (715)635-8629. He can custom make a sending unit AND fuel gauge for you. You need to stay within manufacturer family, Stewart Warner with Stewart Warner or Rochester with Rochester. They will not interchange due to different ohm range use. I fought the same issues as you on two IH tractors before getting Jerry's help with excellent quality and super fast service. Make sure you ground the gauge.

Thank you, Wes!
