Return Fuel Line O-rings (Not for the Fuel Rail)

[Waco84GN]

I need the o-ring that is on the fuel RETURN line that goes to the fuel tank. The line that follows the frame rail back to the tank. I already have the o-ring number ya'll are talking about and it pretty loose on the return line. The return line has two DIFFERENT size o-rings that it needs and I already have the fuel reg. o-ring. The fuel line comes along the frame rails heading towards the front of the car. Then there is a joint where there is hi-pressure rubber hose that is crimped onto metal line. I need the o-ring at that joint NOT the fuel reg. or at any other fuel rail junctions.
