Hi , you can use a T SHAPED connector so you have a return flow to tank
the return may need a little restriction so the flow favours feeding the carb first
or else you will get starvation,
I have a T piece that has a drilled out carb jet in it, for the return flow
that's the sort of thing to overcome the problem
I think they made a T piece designed for that precise scenario,
if you have no jets , something , just to restrict return flow abit
