Plumbing the fuel

Hey guys, just a quick inquiry that hopefully will solve a few day headache for me. Got me a nice little 71 GMC short bed. I pulled the old power plant and swapped it out for a 5.7L tbi set up until i can get somethin bigger and better. My question being, since the tbi is already regulated, is there any need to plumb a pressure regulator? I got a whole new fuel kit, pump, filter, lines etc and the additional regulator came with. Don't want to do more work than needed. Thanks for any help you guys can offer!!!

Re: Plumbing the fuel

IMO you will not need an additional regulator as the TBi has one in it. What sort of fuel pump are you using? Internal or external?

I picked up a kit from jegs using an external pump. And yes the tank has already been moved to the bed. The reason i considered still using the jegs regulator is that its set for a pressure gauge an also reduces the hose size from #8 to a #6 which i figure will make it easier to plumb into the throttle body inlet
