Project: BLACK METAL - '67 Camaro

Unfortunately the way this tube type sending unit advertised is a bit misleading. It may not be as worse as the floating type but that thing still bounces

Yup. They don't actually claim that it will solve the problem. In fact, there's not really even a description on their website http://shop.classicinstruments.com/sn38t. It's just what other people have said in forums that lead me to believe that this would solve the problem.

The closest thing I could find from Classic Instruments were a couple of press releases that said:

HotRodHotline:
"Classic Instruments is pleased to announce the release of a tube style fuel sending unit. The tube style fuel sending unit is the latest innovative product to give your hot rod or classic car “The Finishing Touch”! Tube style fuel sending units are ideal for applications where conventional swing arm senders will not fit due to clearance issues. Tube style sending units are also less susceptible to cause erratic readings due to fuel slosh in a tank where baffles are not present."

Tanks Inc:
"Most aftermarket fuel senders use a rotating float arm and resistance cards to measure the amount of fuel in a tank which can lead to erratic pointer movements. This revolutionary design comes with many benefits! This is ideal for applications where a conventional swing arm will not fit due to clearance issues. The tubular design acts as a dampener to prevent the gauge pointer from moving due to fuel slosh."



I don't know if it's any better than the swing arm one that I removed, but it's not worse, so it's staying put.
