i did the same a couple of days ago. my float was bad(full of gasoline) as well as the f(1)? fuse. my fuel readout system is now working for the first time since i have owned the boat.
i added an inline fuse to the solid pink wire on the outside of the sending unit so that when it inevitably builds up a bit of static electricity, i can easily just pop in another one and head on down the road.
