TWO Sending Units??

[93CalypsoConvert]

My fuel gauge has always read only the bottom half of the tank. Needle never goes much over 1/2 mark. Dropped the tank to find TWO sending units in the same tank... Is this normal or has someone messed with this before? Originally a 4 cylinder car so maybe that makes a difference?

Only the lower unit was connected to the harness. I'm going to hook it back up tomorrow and see what my gauge is doing. The other sender is still in the tank.

The unit you pulled out looks like a carburetor pick up tube and gauge float from the older carb setups (85 and older). The older carb setup tanks did not have the opening in the center.

In your case, the fuel gauge should be connected to the center of tank sender. My guess is you have a car that was fuel injected from the factory - could be either 4 cyl or 8 - (hence the two opening tank) and someone has converted the car to carburetor and just used an older pick up tube (with float attached) to get the fuel out.
