I'm installing a 69 camaro tank into my C10...only problem is the sender that comes with the tank is a 90ohm unit and I'm fairly certain my truck uses a 30ohm unit (some 66's apparently had 90's on occasion, I haven't checked mine yet). Do any of you have any good ideas how to go about doing this aside from a 47ohm resistor wired in parallel across the sending wire and ground wire? I'd like to have a linear gas gauge using my stock cluster. The only other idea I've found on the net was to use a 50ohm linear taper pot placed on the sending wire (can be mounted anywhere) but I've not been able to find any info on it to know if it'll still be linear.

I don't want to replace my dash cluster or get a new gauge unless absolutely necessary.
