Found out my brand new Fuel sender I bought at Carlisle quit working...Gentlemen, The first thing you do when you get one of the newer Fuel sending units is remove the Clear/white plastic float and toss it. I figured I'd Replace with a brass one, quit again...Removed the sender tonight and found the brass one has cracked...
Luckily, I had just installed a fuel pump in a 1997 Lincoln and robbed the sender float off it...Tac. welded the two together and BAM! Fuel gauge works like new again....For whatever reason, when these things are manufactured, they use the plastic floats. When they are snapped into the sender arm, they crack right in the groove where they snap in...Just make sure you get the float tac'd in a Semi-Acurate position to the original.
