IMO I would delete that "T" at the filter and replace it while there. Then run the -6an to the rail, then from the rail to the FPR and from the FPR back to your return line. It's how I have mine set up.

Unless you have plans to use the NOS. Which I have to assume is the "wet" system. Given it's plumbed into your fuel line. I'm not very knowledgeable on NOS systems so hopefully another member can chime in about that.

Other than that, welcome to the board Awais. Glad to see a new member here willing to get their hands dirty
