I just ran the return fuel lines from my 912ULS down under the cowling so any "returned" fuel would just drain out under the plane away from the hot exhaust. I am guessing that not much fuel ever gets returned because I use only 3.5-GPH at 68-70 MPH (4700-rpm) and about 5.5-GPH (5100-rpm) at 83-86 MPH with my Rotax 912ULS.

At least one of the 701s built at Quality Sport Planes ran the line back to a three port manifold on the people side of the firewall. I’ve attached a picture. Presumably there it mixed with cooler fuel coming from the tanks. I’ve attached a picture. Doug Dugger said the part came with the FWF kit from ZAC but that a similar part could be bought from Aircraft Spruce. Look under hardware->fittings->aluminum manifold fittings. I found a similar part at McMaster-Carr, p/n 5469K101 “ALUMINUM MANIFOLD, 2 OUTLETS, 1/4" NPT INLET X 1/8" NPT OUTLET”
