Review: Excellent fit, works great. Very well made. - Excellent sending unit! I built a 42 Ford cabover truck and used a 1949 Chevy truck fuel tank (GM55A). This sending unit fit perfect. The holes lined up perfect with zero modification. I used the 11”. It’s great that they offer this unit in every length. The gauges I’m using require 240-33 ohms. I can’t believe how perfect this sending unit fits and works for my setup. This will be my go-to sending unit for all my builds going forward. Would be awesome if they made them in other ohms as well.
