How to Pump-Up Hydrolastic and Hydragas Suspension

From 1962 to 2002, many BMC, British Leyland, Austin Rover, and MG Rover cars were suspended by Dr. Alex Moulton's Hydrolastic or Hydragas suspension system.
Influenced by Citroen, Moulton developed a springless suspension that rode on fluid, later adding a gas half to the system in place of a traditional shock absorber.
Today on Twin-Cam, we're looking at how you can pump up the system, something that is much easier than a lot of people believe!
