Set up feed and return to the VR6 12V "Big Log" Fuel Rail kit or your mighty 20V "Big Log" system. Add an FPR Adapter and you're good to go. Mount your FPR on either the "feed end" or the "far end" of the rail. It's your choice. The result is full function with easier and plumbing than any alternative.
Note: Barbed fittings are OPTIONAL.
