Radiator Drain Question - Page 2 - ZR-1 Net Registry Forums

I find it easier to just remove the rubber hose on the passenger side that is connected to the 1/4 inch tube at the rear of the engine(goes to the throttle body i think) . Remove the hose and into a gallon jug and blow low air pressure in to the aluminum tube(5psi) . It doesnt leak if you do it qiuck. take out a gallon and yiou can romove the injector housings...I think it easier than messing with the petcock.
