Came across this guide as I was looking into hydro suspension pumps.

Was curious to see if anyone had given it a go. Basically uses a grease gun.

Absolutely - in fact many here use something very similar!

Sweet

Is there a place locally to buy the Tee-coupler?
Also what is a good replacement fluid? Tried doing a search on here but couldn't find anything (might be using wrong keywords)

The coupler that they use is the most expensive bit. They sell for about $100.
You really don't need it, you can just make your own out of a metal valve cap or a valve extension. Cost about $5.

Parker Hydraulics have them (Phone: 02 9634 7777 - they don't appear to have a Vic Office)) but be prepared, they're about $80.00 +

Hydro fluid is available from the major mini parts supplier. Alternatively mix up a good quality antifreeze/anti boil (I use the Castrol glycol) in a mix of 50% glycol and 50% water. I am sure the doc has a recipe?

So basically the pipe is attached to the hydro bag valve.
The grease gun is held vertically with the end that has the rubber pipe at the bottom.
The top end is left off and the hydro fluid poured in and then pump away.
Is all that correct

If so what stops all the pressurised fluid in the system from coming back out like it dose if an air compressor is hooked up on to the car?

If the hydro connection valve is held off it's seat, there has to be a check valve in the system.

My pump is the same setup as Morris 1100's, using a Mini master cylinder instead of a grease gun. It pumps up much faster....

As there is no `valve chuck' on the end of my fill line, the schrader valve in the hydro nipple acts as a check valve. Works fine.

Seems hard to find a grease gun which is open at the end away from the head (so you can fill it with fluid) as they all seem to open near the head to insert cartridge........

This is mine...I used a connection that is used to put water into tractor tyres....was around the $30 to $40 by memory...has a release valve also, handy for bleeding the air out of the pump hose...
