65 C10 FUEL SENDER RATING 30 or 90 OHMS ?? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Need a little help here guys.

1965 C10 LWB converted to SWB

Original gauge cluster with original fuel gauge.

I removed the tank behind the seat and scrapped it years ago, so I no longer have the original fuel sender

Just ordered a new under bed tank from Tanks Inc. and now need to order the correct fuel sender for the stock fuel gauge.
I need to know if the 65 C10 trucks came with a 0-30 or 0-90 ohm fuel sender.

Originally the truck came with an inline 6 cyl engine, not sure if you need that info but just in case.

I have searched here and get conflicting information. Some threads say all GM vehicles are 0-90 some threads say 0-30 for certain years.

Is there a way to pull the gauge cluster and test the fuel gauge without power?

The truck is in pieces since this is a frame off restoration

I do have a Snap On battery charger if I need power or I can use a standard car battery from my daily driver.

Any help or links is GREATLY APPRECIATED

Thanks

Sending units are 30 ohm.

Yep, the fuel level gauge in the instrument cluster reads a 0 ohm empty to 30 ohm full signal.
