Winabbey? posted the hydro evacuation spec on here not long ago.
I've thought of adding a pneumatic venturi vac pump to mine, but IMO it's not needed unless you are replacing the bags or pipes.

My pump is stainless steel with standard rubber seals, so no different to a cooling system in a car and if it did need new rubbers they are, apparently, standard rubber seals available from industrial suppliers. I have thought about adding a vacuum pump to it but haven't had the time or energy to yet. I am assuming that Mick is up to something by his previous post.

TOO MANY MINIS AND NOT ENOUGH TIME

Pretty good
I forgot about mine for a year.... The poweder coating suffers a little, but nothing significant happens to the metal tank. Its about 5 years old now.

I put a filter in the bleed back line on mine as well. Nothing special, just a fuel filter to take the grunge out.

I've not needed a vacuum line, and I replaced the lines completely five years ago. Like Doc has stated you pump them up and let the air gather at the high points. When you allow the fluid to dump back to the tank it carries the air with it. About three cycles is all it takes.

What about the hose, where did you get the hose that fits both the pump and the high pressure valve exactly right?

I used the hose it came with, and picked up an adapter from Enzed to suit the thread change.

Thanks Mick, sorted a hydrolastic pump! This project has been on the back of my mind for years

Hi

I have used the pump in the photo a number of times to test firefighting pumps and suction hose and as well as other firefighting equipment. Vacuum and Pressure testing.
It would last you a life time if you are going to use it to pump up your mini to the correct height.
That model is well made in my opinion and easy to operate.

I made mine using one of these pumps, but i bought a cheap vacuum pump off ebay as well and teed it in
So i vac out the system until no more liquid comes out
then let it sit to see if it loses vacuum
Then i change over to the pump and let it suck it in and pump as well to ensure it goes all the way to the front
Used it a dozen or more times now to flush the rubbish out of the system

Thanks for all the advice guys, mission successful! Pump works perfectly! I've been meaning to sort this issue of hydrolastic pump for nearly a decade and this is by far the best and easiest (and possibly cheapest?) way to do it. It will certainly last a lifetime or two
