OK, so I’ve scoured previous post about this topic and I’m now at this point.
-cleaning up some previous owner work
- VDO fuel gauge part number V301030. Rated 0 to 90 ohms.
- New stock sending unit putting out 36 ohms now as gas tank about 1/2 full.
- all wires continuity tested and I’m sure i all hooked up correctly. Yes-grounds all
checked.
Problem- gauge reads full.
-assumption the pin configuration on the sending unit plug is correct- see pic

Fix?
- install VDO gauge v301020. Range 10-73 ohms
- Will this gauge work close enough with the stock sender?

Or…. Do I need to replace the stock sending unit to match the gauge ohm range exactly?

Thanks for the help

@914sixer
References I’ve seen is the stock is 0- 70.
I’ll keep looking into it just in I’m wrong.
Thanks for the info Todd
