From reading the main part of this site, I gathered that it should be possible to inflate the airbags on the car by using a manual pump.

I thought I'd give this a quick go so removed pipe number 4 from the EAS unit, was a little surprised that air was released from the pipe only for about a second or so.

I made up a quick adapter pipe to fit between an air gun and the eas pipe, and slowly started to allow air in, the pressure went up quite quickly but the car didn't lift, I didn't want to cause any damage so stopped quite quickly. On pulling the adapter off the pipe swirled about in the air making lots of whooshing noises.

So before I continue and break anything was I doing it right? Shouldn't there be a 1 way valve to stop the air coming back out?

if you want to try manually pumping up the system,rather disconnect the air line from the compressor to the valve block,and then pump up using that line.
myself and others on this forum have fitted a permanent manual pump up system.The timer relay under the left hand front seat has to be removed when doing this.
why do you want to manually pump up anyway?

#4 is for the right front, and you need 70psi to lift it. #6 is for the air tank.

If you plug into the compressor line you need to jumper the comrpessor relay to activate the diaphragm valve, or all your air will just go out the exhaust.

You can pull the airline from the top of the dryer and put shop air directly into the top of the dryer with an air-gun, it will lift all 4. not sure why it works, logically it shouldn't, but shops do it regularly.

I want to see if any of the airbags have leaks. The car has been sat for a year or so on the bumpstops. The engine is currently in pieces. I have tried to jumper the EAS connector under the seat but it didn't work. If I connect 12v to pin 8 though it does run the compressor, but I can't activate any of the solonoids to lift any of the corners up.

It was #4 I was using, should it have blown back like it did when I released it? I'm not sure what PSI I was up to as I didn't have a guage but to me it didn't feel right and I thought perhaps I would need to open a solonoid?

You mention needing to jumper a relay - is that required to do what I was trying to do?

You mention connecting directly into the top of the dryer. Which bit is this? Have you any more detail on this. Will this work with no power to the vehicle?

I often use this method, but never had a car raise just by blowing air into the dryer line. As far as I understand, it is a way to fill the tank without straining the EAS-compressor (for example after changing airbags). To raise the car I either turn it on (with the shop compressor still filling the tank) or use Rovacom to activate the valves.

That does look interesting. I can't view the pics though as it requires registration - any chance of posting them here?

So can you confirm if pumping straight into one of the airline should inflate a corner whilst the battery is off the vehicle - or does some kind of valve need to operate to let air in?

If you go straight into the airline for the spring it's a clear shot, it should raise that spring.

Sorry if I'm sounding dumb, but I need it as clear as possible...

If I take the pipes of the back of the Valve Block where they are numbered 1,2,3,4 and blow air into those pipes is that straight into the spring? If not where should I take the airline which is straight into the spring?

Many thanks

You got it, 1,2,3,4 goes straight to the springs

Do they have a non return valve? Or is that in the valve block?

I only pumped a bit of air in incase I was doing it wrong but as soon as I disconnected it, the pipe wooshed away and wipped around for a few seconds

No one way valves, the airlines go straight to the airbags with nothing in between.

That'll be why then! Don't fancy putting much more pressure in if they'll just blow back like that! Will have to try and find some valves and make a MARS type system
