Tincup's 63 Dart w/5.7 Hemi

My question would be what would fit into a stock gas tank for a sending unit....and why would they not work with aftermarket gauges....are you running a cell?

IF so I would think the makers of the gauge would have a sending unit or at least factory support to help find one.

I am using my stock gauge and sending unit but I would love to know this answer as well......my next project is gonna be a gasser cuda.
