Adding a few new holes in the floorpan for clamps on the rubber lines will be needed. Better to secure it away from any heat or vibration vs having a fire.
Best option for fuel line long term is a hard line front to rear with the AN line to the tank and to the rails. Runs along the stock path. Couple clamps to hold it down and away from vibration or heat sources.
I use the Right Stuff line and cut and flare it for AN. One cut and flare near the tank. AN adapters for feed to the regulator. AN lines to the tank from the regulator. Another cut and flare near the passenger footwell area by the subframe. AN line to the fuel rail.

I buy the Fragola premade AN lines to make my life easy. Leak free everytime. No AN lines to make that I have to pressure test for leaks. I do pressure test the entire system and blow it out before I run gas thru it.
