this way works excelent. i took a 1/2" piece of plate and welded an air fitting into it. i use a quick grip clamp to hold it on the resevior. i have done 3 or 4 cars since i made that thing and it works great. top off the fluid after you do the rear axle, then again after you do the front wheels. or you can top it off after each wheel.wedgie said:
