New fuel sending unit help.

I am also replacing my tank on my 1970 Duster (No Fuel Pressure after driving car.) I also decided to go 3/8 line for future motor build. I think we are limited on sending units for 3/8 lines without vent tube. Mine was listed 67-74 A-Body and the vent I assume is for 72 and up. If anyone knows a place that has the 3/8 sending unit without vent port please let me know. I really don`t want to have to just block this one off. ( UPDATE UPDATE) After searching on FABO I have found a place that sells this without vent tube and is 3/8. Sending this back to summit and eating the shipping charge and car will be down another week.
