67 fb (with 69 pont 400) and a mechanical fuel pump. the return fuel-line is long gone, it now has a mechanical fuel pump with a return outlet. if i dont block it off(return outlet), fuel runs out the bottom.(motor running or not).
Question is...is there any harm in placing a T into the fuel inlet line and having the return line attach back to the T ? i figure its the same as where the fuel will end-up anyway...just cutting out the return to the tank.

OR do i just drive it with the returned blocked off?
and does this cause and overload in the fuel pressure to the carb or pump?

just getting this her back on the road and tring not to do anymore road-side repairs as possible. thanks
