I've searched the forum but can't find a similar question so I'm looking for a little help. I just installed a new gas tank and sending unit in my '57 and the original guage now goes rather quickly from full to a quarter tank but when I add gas, it is full after only 8 plus gallons so I'm basically still at a half tank. Is there some way to "calibrate" the new sending unit to the original gauge? Any help would be appreciated. AWC

If it is stock it might just need to have the sender armature bent. I had to do that when I installed a new tank and sender in my '55 to get the gauge to read right. PIA to do yet I like to know how much fuel is in the car :)

Classic57 is it a stock 30 ohm sending unit?

Thanks for the help. David, I'm going to pull it and check but it should be a 30 ohm. It came from Ecklers so I "assumed" it would be, and I'll see if the armature needs tweaking G.R. - I agree on the PITA. I was hoping there was a simpler solution but you're right, I need to know what's in the tank. AWC
