How to: Pump up MGF hydragas with liquid levers pump

OK, this might not be of use to many as they dont have a pump, but it may be interesting for people to know how its done.

First of all, measure the ride height at front wheels, between center of wheel cap and the wheel arch of the front wing. this should be 368 mm +/- 10mm at 17C. (or 348 for a Trohpy)



Today it was exactly 17c so that was nice!! My D/S was 350, and the P/S was 340!

Then you need to remove the underbonnet shroud.

This is the view upon opening the bonnet (though you probably wont have a bottle of pre-diluted coolant in there)



There are two nuts to the left. These are bolted to a flimsy and probably rusty thin bolt which is attached to the car. Its easy to damage these, so best to soak in release oil for a few minutes. When removing, if you can pull them up at same time as turning them, it helps them to come off without stripping thread.





There are two of these bolts at the bottom of the shroud at each side, but I have yet to see any with nuts on them...if they do on yours, then you clearly have to remove them




Now there is a plastic (wtf) bolt thing at the front of the shroud near the top right.



One I have had a little central plug in it, which when pushed in, closes the bolt. I have no idea how you are meant to remove these, other than just pulling!! (i have a spare handful for when I do someone else's car). y last car had a plastic screw which simply broke by looking at it!





Now you can remove the shroud and you can see the hydragas pipes and dust cover caps, same as those on wheels.





Ok, now to the hardware. this is a liquid levers non-vacuum pump.




Its quite simple in essence. A reservoir, pressurised system and a pressure gauge.

And some fluid






The adaptor has a pin which seats int he "car valve" to open the system, when turned clockwise.



Don't be tempted to press the pin in the valve in the car to see what happens. You will be immediately covered in a spray of hydragas fluid. Although as its mostly alcohol, it smells OK (I dont know how I discovered that out), but can damage your eyes!

I have prefilled this with about 1/2 volume of hydragas fluid. Valve is closed on the system and adapter is turned fully anti-clockwise to ensure it doesn't push down pin on "car valve"



Its advised to wear safety goggles before this step and throughout the rest of the process. I made sure tube was full of fluid by pumping system with valve into the fluid container, to prevent any air getting in. Now attach adapter and tighten. Now turn valve clockwise to open up car valve.



Now you simply pump the handle. At first its like its not going to budge and you have to keep pressing and then it gives way and you can hear the fluid going in and you can watch the pressure but its more important to measure the ride height as you go add a few pumps, until you get to correct height. The pressure will vary depending on the state of repair of components etc. for example, I pumped up mine to 365mm, which was about 410 psi on drivers side, but was about 350 psi on passenger side!

Once you are happy with height, turn valve anti-clockwise to close car valve and then open main valve in pump unit to release pressure, then close again and remove adapter, and replace dustcap.

Then simply replace shroud and job done.

I think someone had a thread on this recently and the pump didn't get the best of reviews but the feedback on the listing is positive

Looks like a draper grease gun which has been modified. This DIY method is on the net and it seems to work, I suppose. Don't know if I'd trust it at >400 psi myself, but it just be OK
