Fuel/Return lines for Dual SU's

[That4doorKiD]

L-18 with twin SU's in my dime. I need to put my return line on my gas tank , and I don't know where the fuel feeds or return hoses are on the carbs :poop: . Anyone know,

I don't have experience with these carbs. :blush:

They don't use a return line.

They don't use a return line.

YESSS! thank you. In fact, my return line was all bent up, so good thing I won't have to use it :thumbup:  :thumbup:  :thumbup:

510s don't have a return line either.

 

You are probably looking at the tank breather line. Don't block it. Don't let the gas fumes out either. See http://community.ratsun.net/topic/56880-fuel-tank-venting/

If you don't have the fuel rail that goes with them, just use a T with equal length hose to each carb. The inlets are on top of the float bowls. Learn how to balance them and don't forget to hook up the vacuum advance and pcv.
