Fuel Line Update, Winter Project Options

[SteveL]

74 1.8 - I previously replaced the 3-port fuel pump with a 2-port pump, mounted to the engine firewall. I have since sent the 3-port pump in for rebuild and have it back.
I have been fighting fueling issues for a long time - fuel pressure drops to 0, engine bogs down/dies. Wait a couple minutes and starts again. I'm down to assuming that there must be a fuel line kink, or a fuel line collapsing somewhere.
SO - winter project - All New Fuel Lines.
I need some help from the collective brain trust please. Do I:

1: Move fuel pump to frunk by spare tire, stainless lines thru tunnel, new rubber lines everywhere else
2: Leave fuel pump on engine firewall, stainless lines thru tunnel, new rubber lines everywhere else
3: Revert back to stock setup with 3-port pump, stainless lines thru tunnel, new rubber lines everywhere else

To complete the above - what do I need to order for the stainless line update, and who is the best to order from? Are they all made by the same person, or are there differences? (and do I need the reducing stainless line from CFR?)

Thank you in advance for all the help - Steve
