Has anyone used steel fuel lines with there TBI intake along with a H/O fuel pump? If so how did you go about doing it? Any special parts needed? What fuel lines did you use? What pump did you use? And whats the highest fuel pump out there for the TBI. Should I just move to aftermarker universal fuel pump? Can you use 3/8in lines?

Sorry for all the questions I am trying to figure out my fuel problems.

 

Walbro 255 is best out there, some guys have reported not being able to turn the fuel pressure down enough after installing. Theory is that the return passages in the regulator are too small for that much fuel at idle. Walbro also makes a 190 L/hr pump that will also get the job done. You'll run out of injector way before you run out of pump with one of these bad boys. Good thing is they are only about 120$

Not sure what you mean by "steal" fuel lines. Most people just use the stockers.

 

im running a 255lph walbro unit in my car and it runs fine w/ the stock regulator and lines... 255 is kinda more than youll ever need for anything along the lines of a stock to mild LO3, but that being said the stock pump is a piece of crap and will not flow enough so a TPI fuel pump or a walbro 190lph pump will handle pretty muc everything that you can throw at your motor... but FYI the walbro 255 works fine w/ stock plumbing

 

So at 30-40PSI with 90 pound injectors my stock lines will be fine with a 255?
