I made up a couple of fuel lines for the supply and return from the Corvette style filter/regulator. I used PTFE tubing and the proper fittings. Not so sure I like how these fittings connect to the filter/regulator. I may change my mind on this.
This is the Wix 33100 filter/regulator.
Made a supply and return line for connection at my Walbro pump inside the Rick's tank.
I don't really care for all these connections on the filter/regulator.
