kit is used. i decided i want to keep my car running so i can sell it so i took it off. everything works good. it comes with a dyno tune digital pressure gauge which alone retails for $180. also a dyno tune purge solenoid and NOS brand bottle heater. come with a 10lb bottle which is full if someone does local pickup otherwise i gotta empty it. comes with nozzle, assorted jets, WOT switch, arming switch, brand new relay and all lines are including a 3 ft extension with union and the nylon purge hose. im asking 550 shipped which is very reasonable for whats included. 525 local pickup and you get a full tank of N20 ($40)
