Trying to solve my fuel gauge problems so I decided to buy a Bill Rolik 440 sending unit. Pulled out the Spectra unit and found fuel in the plastic float. (WTF?!?!?!). Quite the difference between Bill's unit and the Spectra unit. Bill's unit looks top quality. I've attached photos of Bill's compared to the Spectra unit. First 4 pics are Bill's unit. Bill's unit has (1) a metal strip instead of a wire running from the float apparatus up to the top (2) a brass float, (3) much beefier filter sock, and (4) the float apparatus is much beefier than the Spectra unit. No idea who makes Bill's unit though, came in a plastic bag.
