Let me know how your fuel tank gauge issues get resolved.

Using 0-90ohm Autometer gauge, and CR tank sender which is supposed to be a 0 - 90 ohm also.

With 5 gallons, gauge reads 1/2. With 10 gallons, gauge reads full. Any more fuel and gauge pegs. Anywhere between 1/2 and full, needle swings wildly with any movement of the car.

Called CR for a replacement tank pickup and sender. They're on backorder.

Next option is to get a sending unit from Autometer, and another fuel gauge that matches the sending unit from Autometer. The 0 - 90 ohm won't work. So the dash has to come back off to swap the gauge if I go this route.

Next option is to have a 0 - 90 ohm sender made by a street rod gas tank company. I just need a model to use for measurements. If I can get my hands on one without using the one that's in the car now, I'll do it, and have prints for replacements. Otherwise, I'll wait until winter when I'm more inclined to take car off the street.
What I want to do is have all the parts I need to fix this before dropping the tank.

As irritating as this is, the car is drivable, and this is driving weather. Around the end of November, the weather will turn crummy, I'll take the car off the street, pull it apart and fix it.
