I purchased a fuel sending unit from Firestone Collectibles on ebay claiming to be for a 63, 64, 65 polara and fury. I had it installed and it just doesnt operate right. I have driven it about 60 miles, 318 ci, and the gauge is still above the full mark. Actually the needle goes up to the midpoint on the F. Now that I have a few miles on it, when I accelerate it does drop down almost on the Full line, normal speeds or slowing down, up it goes again. After the shop installed it they mentioned that it was different than the orignal, The longer portion was shorter than the original and the shorter portion was longer than the origianl. Any thoughts. I think it is compelety wrong. The seller has said he hasnt had any problems from anyone before. I have asked him for the part number, no luck. I offered to send him my old one and send me a match back. no luck, still thinks it is the correct one he sent me and says i should run an electrical check on it or maybe it is something in my gauge cluster. Any comments and thoughts would be greatly appreciated. Wayne Huseby 64 polara 500 2dr ht ---- Please address private mail -- mail of interest to only one person -- directly to that person.
