I'm getting ready to help my friend put in a zex dry kit. but im confused on where to hook up the "regulator" hose. im assuming the intake hose goes to the intake manifold where fuel will be injected, but it doesnt have an unused port (what to do here?" the instruction says to connect the "regulator" labled hose to the fuel pressure regulator vacuum line. but this doesnt make sense to me. im assuming im supposed to hook up the "regulator" hose somewhere before fuel goes to the fuel rail...can someone help clarify?
thanks

 

where should i put this thread? LOL

 

Follow Vacum line from top of FPR, disconnect it where it goes into manifold or tee, hook that up to where it says regulator on the ZEX box. Then the other vacum line goes from where you disconnected the FPR vacum line hose (Manifold or tee) to the other nipple on the ZEX box.. Clamp all thos vacum lines buddy.. hope this helps..

 

yep he is correct

 

so you're saying the vacuum line that meets the manifold gets connected to the zex kit on the regulator port, and the vacuum line that meets the FPR gets attacted to the intake part of the intake port on the zex kit? then the FPR and the manifold dont have anything attached to it? im so confused...the things i do for a friend
