Yes. Our retrofit fuel system does have a restricted return line. There is a difference in the placement, but the orifice restriction size is matched very closely to the restrictor size utilized in the standard kit.

If you would like to see the installation manual it shows both the restrictor as well as how the system is installed in the RV-12.

Here is a link to the kit

And here is a link to the install manual

(The TS Flightlines/Aircraft Specialty retrofit kit uses AN hardware and not banjo bolts and is not affected by this.)
The standard Van's supplied installation is not effected by this either (the attachment of the fuel pressure sensor is done in a totally different way) so whether you have the standard installation or the Flightlines kit they will perform the same.
