That is the only way to do it with the grease gun otherwise it takes forever.

I've been pleased with the ease and lack of fluid loss with this method.

Thanks to everone who replied. I finally got the mini pumped up. To velopackrat, I agree the hand pump delivers way to little fluid per stroke. The way I finally got the left side to raise, was pretty much just due to pumping,bleeding,pumping,bleeding (you get the picture) and pumping some more. When I finally stopped getting air up front the car started to raise and then I jacked some of the weight off the left and was able to push more straight fluid into the system which raised the car to the level I desired.

My modified grease gun took FOREVER to pump up a side due to the tiny amount of fluid moved per stroke. I cobbled a second homemade pump using a spare clutch master cylinder. Had to source a one way valve too. But the difference was marked. Much easier. For purging the system, I used a Mighty Vac with a schrader valve attached. I don't think it worked 100% - but like Catalina mentioned, bleeding the sytem once or twice seemed to sort it all out.

What part of the country are you in? If you are close to east Tenn, I have a factory pump. It has one side for evacuation of fluid and one side for filling. I also have the proper hydro fluid, wou are welcome to a fill.

Pump it up and then let it down. Every time you let it down you will purge air out.
Keep doing this a few times and it will all be gone. (I have been doing this for 35 years.)

Does anyone here have a detailed discription for pumping up the hydro. suspension on a 1965 Cooper S, using a converted grease gun hand pump? I can't seem to totally evacuated the systen and therefore air is traped this happened on the right side also but when I opened the hose at the front bellows the air escaped and everthing was OK. Right side seems to be fine but the other (left) is impossible to stop getting air trapped. Any first hand knowledge or direction to an article covering this procedure willbe greatly appreciated. Jim
