Hey guys if I install a holley blue inline pump between the tank and lift pump do I still need to put the regulator with it the reason why I'm asking cause it is rated at 14 psi and a lot guys here are running 20 psi with aftermarket fuel kit also should I go head and build a relay system for it or should I just tap into the lift pump power wire

 

I got the dual relay system from Vulcan at the same time I got the big line kit. I run no regulator. Fuel pressure NEVER drops below 16psi, no idea how high it is. No problems starting either. Too much is better than not enough.

 

I made a jumper to plug in from the origional harness than into the pump, the power wire is tapped and run to a relay. the relay is run from the battery to the pump. so the holly pump cycles with the factory pump. and I can unplug my jumper and plug the unmodified harness back into the stock pump. works great, and very cheap/
