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.
