you can, but thats "really not recommended"

I saw this post and the guy used rubber fuel lines to add the fuel pressure regulator.

you can, but its really not a good idea. hose fails, rubs through, it just the pressure in the hose can bust it.
back in the day a friend changed his rad in a 77 caprice, the trans lines twisted, so he used enforced rubber hose and two clamps on both sides.
dont ya know the lines blew and his car burned in my driveway. aka the FD had to come put the fire out. ive never used a rubber line since.
You have to get "fuel injection" hose, different than regular fuel hose. I had to use a section with double clamps to connect the plastic line from the tank to the fuel rail. The Dorman nylon kit kept leaking at the splice barb.
Well, it's been a fun job and should be wrapping it up this Saturday night. Word of advice if anyone else plans to do this...I ended up pulling the master and ABS unit as a whole out of the car. Trying to save bleeding the master, but we'll see. This is the only way you can successfully attempt to snake the lines along the firewall.
I personally think it's impossible to bend the line one at a time and stick them in there without dropping the motor and trans. What I ended up doing was bending all the lines along the firewall outside the car, then inserting them into the clips also outside the car. I extended the lines about a foot past where the lines would bend under the car and union them together with lines under the car. You can easily snake the firewall lines together as a whole back in there. Of course, once the lines are all connected, you'll have to verify the lines run along the firewall didn't move and aren't rubbing each other.
Also, it's crazy what local auto parts stores want for brass fittings...3-4 bucks a pop. Buy them online. I would literally have 100 bucks in fittings, where now I have 35. The quick connects towards the back of the car were stuck cause the lines were so rusted, but be patient they will come out. Luckily my tool can bubble ends for the quick connects too.
