Fuel sender 12v upgrade

[Fugal 41]

Look up, VDO Reed Switch Fuel Sender - 150mm - 240-33 Ohm, #226-615.
My 1941 Ford conv. coupe upgraded to 12v fuel sender never ready worked right. Some days better than others. I realized that the sender in my boat would work in the Flathead. Comes pre wired with gasket. Will it work on 6v with a resistor, I don't know. My tank is 6.5: deep > relates to the 150mm.
240-33 ohm for the 12 volt gauge. Check it on the internet. See ya

Since the 1941 gas gauge and sending unit DO NOT operate on the Ohms Principle, I doubt if it will work, even with a 6V resistor. However, if you find out otherwise, be sure and let us know. Sure would solve a lot of problems. The key is it must work ACCURATELY.
Please be sure to let us know.

Well I found out the hard way not to buy off an off brand. The proper Reed Sending unit is made by Rochester Gauge. One I received in the first post "VDO Reed Switch Fuel Sender - 150mm - 240-33 Ohm, #226-615" from a Ebay seller is a bad knock off. Sorry for posting information before I had a chance to fully try it out.

Thanks Fuel 41 for "running point" on that bogus fuel sender.
Sorry it didn't work out.

The OEM gauges work on variable current flow so I doubt you will ever find a rheostat type sender that will ever meet the range that might work it accurately. It would be a lot easier to just modify the gauge cluster for a 12-volt rheostat type indicator and match it to a rheostat type sender that will fit in the tank.

I installed a 10-73 ohm sender from Yogi's street rod parts in my '41 Ford 20 yrs ago. Connected to my stock gauge with a Ron Francis 12-6V electronic reducer.Works like a charm. E is EMPTY, F is slighty over Full with 17 gal.
