What's a good replacement for a gas line on a 75 Dodge truck? From tank to fuel pump? Steel brake line, copper , rubber line? Thanks!

Copper would be the easiest to work with as far as flaring for fittings and such.
Steel line is good too,but would want larger diameter than brake lines.
 I would stay away from rubber.

True not sure what the diameter is now but thinking at least 3/8 ,

5/16 would be plenty!  1/4in if not performance.    as far as what to use.  rubber will last 10yrs and is easy to run and ez to replace.   also if you have a spot where rubber might be a problem, run copper thru that spot.  2 hose clamps and that problem is taken care of.  don't forget if fuel lines are rusted, brake lines will be next!  Now if doing a frame of restoration; then all these recommendations are for not!

check out places like summit or Jeg's, or some of the resto places, I think you can get stainless steel replacement fuel line reasonable
I would not use copper.... last resort would be the copper for refrigeration, its thicker, harder to bend, and higher grade,,,
