Posted: Mon Nov 10, 2008 8:32 pm Post subject: Wire Size For VDO Fuel Senders

I tried to find information on this in the archives, but was not successful.  Can anyone tell me what size wire I should be using for the VDO fuel senders?  From my reading, I understand that wire should be sized based on the current load of the device and any derating factor if placed in a bundle.  However, there is no amperage information provided with the fuel senders.  The only information I could find, in the assembly guide, is the variable resistance (from approx. 70 ohms at empty position to approx. 10 ohms at full position).  Does the wire size actually depend on what I will be using on the other end for the  fuel gauges?  

Thanks for any help you can provide,

The only gauge on your panel that has any significant current flowing through is the ammeter. All the other gauges will have something on the order of a few milliamps. The current flow is not an issue for the sizing of those meter wires, the resistance of the wire is a bigger factor. You don't want to go so small that the resistance of the wire effects the accuracy of the reading. 



You shouldn't have any problem using 18 ga. or larger for the fuel sender lines.
