On roots draw through blowers you do not.

Can I hook it to the forward 3/16 barb, or should I hook it to the rear next to the 3/8 barb? Would be nice if you change your directions. Thanks Bryce - FiTech Tech Pro November 22, 2016 As an update we are now running the regulator port to manifold vacuum. The easiest spot is on the back of the throttle body on the 3/16 barb next to the Idle Air Control Motor. Mike January 17, 2017 Just ordered the EFI 8 1200 power adder system, I’m going to be running It with a blow thru. First do I need a seperate boost referenced fuel pressure regulator? Second, if I don’t need a seperate regulator where would I hook up the boost reference? Cody- FiTech Tech Pro January 17, 2017 If your pump is over 340LPH you will need a seperate regulator, if you are 340lph or less than you can use the existing regulator hooked to manifold vacuum/boost port on the back of the throttle body.
