OK, I took the advise of all you savy builders and moved my Dukes Fuel Pump from the firewall (outside) , to under my seat. The installation went quite well, xcept that now I need and overflow line to the outside.I am having a terrible time finding the proper fitting. It seems to be smaller than a 1/8 inch pipe thread. Can anyone tell me exactly what they used. Sincerely, Fred N9BF

Fred,

 

I believe It is a 1/16 pipe fitting - See:

 

 

This is 1/16 pipe to 1/4 tube for about $2.5.  Always refer to Kit Components for weird parts advice.
