Hydragas Pump

Sorry for the delayed response, I am based near Tunbridge Wells.

Thanks for your input. 

Hopefully its a one off job, so I am reluctant to overspend   if its not  necessary. 

Did you manage to get the job done without the extra tap n vslve attachment? 
i was wondering iif that is necessary to enable you to complete the job, or if its an add on that without,  you risk pressurised spillage,  but can still get the job done. 

I just bought a Katsu pump which worked perfectly well to fill the system and then drained any excess with the screwdriver and milk bottle method. No need to change anything. Its dead easy stuff.

Update for anyone else considering purchasing a Katsu Pump, to recharge their suspension:



I completed the job today, without any issue. 
The Katsu Puma,  pressurised my suspension from 200 psi to 450 psi and raised my suspension by a few centimeters. 
Based on that, I highly recommend this product,  particularly if you pay extra for the isolation valve, which minimises the risks of high pressure spillage.
