fuel gage error after replacing fuel pump
I have a problem I replace the fuel pump and now my gas gauge is full all the time. Some people who replaced their fuel pump their fuel gauge shows empty all the time but mine shows full. Could I have put the floater in the wrong position when I was setting the fuel pump in the tank. Going to look at it now. Any help would be appreciated. If its the fuel pressure sensor which gave me the correct fuel level readings, could I take it off the old one and put it on the new one?

I moved your post to it's own thread.

I'm guessing that you got the wire color codes mixed up. They changed the wiring at some point.
The fuel level is measured by a float.

the key point in Oldblue's must-read thread link: "Well, I finally switched the two wires from fuel level senor and the gauge now works. .......................... Blue goes on the left and purple goes on the right."

*UPDATE* --- Thank you guys. I should have mentioned a purchased a used fuel pump out of a wrecked car from a salvage place. When installing the "new" fuel pump I figured I might have adjusted the float on the wrong side. Since the original fuel pump level sensor seemed to work, as I always correctly knew how much gas I had in the tank, I took the original one off and installed it in the "new" one. It now works! The fuel pump I had bought either had a bad fuel level sensor, which is a little black assembly with a varistor inside to adjust the fuel gauge dial accordingly or because as I noticed as i was taking the one off the "new" pump the rod attached to the float was not seated properly in the connector that held it to the actual sensor assembly. That being said I never had to adjust the blue or purple or other color wires that some people had to mess with in my first attempt as I bought a "new, lightly used" fuel pump. Thank you all for the help.
