I ended up drilling , tapping and then soldering over a brass fitting in my original sending unit , No problems at all . in the picture you can see were I put the bulkhead fitting in for the return line, above to the left of the sending unit , the vent hose runs to the passenger door ,I pulled out the upper rubber grommet door stop and put the vent line through that exsisting hole, fit 1/4 hose perfectly and vents with no issues.
Thanks
