Fuel gauge sender OHMs

[weimarbus]

I have the fuel tank out at the moment due to the gauge not functioning fully. Do any of you helpful people know the ohms range for the tank sender 251 919 051 E with my multimeter on 200 ohm range I am getting infinity at lowest movement then just off there 184 ohms (reserve) and 52 at the highest (full tank) it is still only showing 3/4 tank at 52ohms after cleaning all contacts, track,wiper, connectors etc and engine running, the issue was that even when full the gauge was only showing just under half a tank, maybe the dash gauge needs a bit of vibration and time to get used to being full again. I have only been keeping 1/4 tank or so in reserve cos I have used LPG for the last 10 years approx. The gauge did work correctly back then and with LPG being harder to find would like the tank gauge to be more accurate.

I found this on another thread...

Going by this-

34 Ohms = Post-85 Full
37 Ohms = Pre-85 Full
168 Ohms = Post-85 Start of Reserve
288 Ohms = Pre-85 End of Reserve

Many thanks Robsey, will send an email to Heritage and see if I get an answer, they wont speak to customers now on phone, as with many companies they are too busy and too important to deal with plebs ( customers)
