I got a fuel sending unit from Livorsi Marine that works great . It's a tube style so the guage doesn't bounce much . I can't seem to find it at their web site , http://www.livorsi.com , but if you call them , they might be able to help you out . It' a 3 wire hookup .

Make sure your tank is grounded,I also went with the same style as Redboat.
