hard to check that out, the cherokee wasn`t mine, must be torn to pieces right now, but i got the lpg system for free so i can`t complaint, i have:
1- a vaporizer unit, with both in/out water hoses, a low pressure hose and a solenoid actuated high pressure valve
2- a mixer that goes between the throttle body and the air filter.. never seen those
the only thing missing is the tank, someone else beat me to it, and i know for certain it works because it was running, but the transmission didn`t work and the frame too bent to be usable
i`m at home now, the equipment is in a friend`s house who`s giving me a hand with the conversion, i`ll take some pics tomorrow...
