      FPR suggestions and installation

      I am having hot start and boiling fuel in my 73 Bird. Setup is as follows:

      466 roller cam, ported heads guessing somewhere between 400-450 HP
      Holley 850 DP warmed over by local builder
      Carter HP mechanical pump
      Return line and vent are caped off.

      My plan is to run the II much vent off the vent tube from the tank and put in a ventless gas cap.
      Get a regulator and run a 3/8 return line back to the sender down to a 1/4, so if I go FI later I have a bigger return.

      I think these two things may make it able to drive the car above 75 degrees outside. The II Much Vent seems pretty straight forward, but the regulator and line are a bit of a mystery. I'm thinking of running a 3/8 premade line next tot he stock fuel line for the return then a teflon line to the pump.

      My real question is which fuel pressure regulator do I need (I assume bypass) and where\how to install? I'm pretty ignorant to this stuff so if someone has experience with setups that work I'd happily copy, I'd also like to get a FP guage somewhere.

      Thanks!!

      You will need a bypass regulator. Why not go with one of the Holley ones? It should be mounted somewhere in the engine bay. Your plan to run stainless hard line and teflon hose is sound.

      yeah I've seem them but not sure which one to go with, some of the posts I've been reading up on say the regulator should be on the fuel log?

      So I'm looking at the Holley bypass regulator and its says not to be used with mechanical pumps?? So Do I get hte non bypass one then run the return line from the pump itself? Run the fuel line from the pump through the regulator?

      I think I have the II Much vent figured out I'm going to order and put that in first.
