How would you run the return ??

I’ve got a brand new spectra fuel tank about ready to go in my 71 demon along with a new 3/8” sending unit. I run a Mallory elec pump and will be using a return style regulator to help ease fuel boil over when parked hot. I will run a 3/8” return back to the tank.

The sender has the small vapor 1/4” fitting so I’m not sure I want to drill that out and try brazing a 3/8” tube on it, risking damaging the sender . Would bringing the tank to a radiator shop and having them braze a tube in next to the sending unit work? Seems like a good option since the tank is new.
What do you think? Thanks again!
