EJ22t won't start, floods with gas

So, I finally got around to doing a fuel pressure test, and this is definitely the issue: 66 psi!
So, I think I'm going to end up replacing all of my fuel lines (feed and return). Does anyone have any suggestion on what to use? Can I just use regular rubber fuel hose (MPI rated), or should I use SS braided hose, or something else? I'd prefer not to use hardlines, just because I don't like dealing with unions and bending that length of line.
I would not bother replacing fuel lines.
I would make sure the return line from the FPR to the tank is open however.
Maybe direct it into a gas can for testing purposes.
Give the FPR a few love taps.

I thought I'd post my end results in case this helps anyone. I've finally got the car running reliably.
I did another fuel pressure test shortly after I did my initial fuel pressure test, but this time I did it on the return side instead of the feed. There was ~80psi on the return, which confirmed my suspicion that something was wrong with the fuel lines.
I made some SS PTFE feed and return lines, and replaced all of the lines from the tank to the engine. After driving the car for a few days now, the plug have cleaned themselves up (they aren't completely fuel fouled black anymore), and the car is running great, smooth as ever.

Glad you got it running.
