Doug, that's exactly what I did to the fuel senders I modified for larger 
dia tubing (more fuel flow needed for high horse engines), except I brazed 
the tube to the fuel sender cap. Before you do it, you'll have to remove the 
tank gasket, drill out any rivited   electrical connections and remove 
plastic spade-lugs and the tiny o-rings that seal them off. All this stuff will 
melt or burn during the weld/braze. Once the weld/braze is done, you can use 
non-rusting ss screws and nylock nuts to reassemble the sender's top 
connections in place of the rivits. 
If that sounds like a lot of work, its possible to drill a hole & clamp the 
extra line to something on the sender inside the tank (Not familiar with 
Mustang senders), and seal it off with a bead of BONDO inside & out! Bondo or 
J-B Weld, once cured is totally fuel-proof but isn't very structural so you 
need to rigidly clamp the line, or it will flex & the Bondo will crack while 
you're twisting a hose on. I know it sounds red-neck but I did this to our 
Pantera sender maybe 10 years ago for an extra fuel-out line, and no leaks 
or even seeps yet. 
Remember: most car fires in performance machines come from mucking around 
with fuel lines, fittings & hoses! Good luck and be careful- J Deryke
