When uninstalling my zex kit there is a hose the went into my intake manifold, now that it is unplugged i do not know which vaccum hose goes in it place. There is also another vacuum hose that goes into the fuel regulator from the zex sytem as well, someone told me that I will have to get a stock fuel regualtor because the one I have now is an aftermarket adjustable one. Any advice let me know, thanks....
