I have now put on a new pneumatic casting with new reed valves and it takes a long time to lift the car and the pump is really hot!!!

Do I need to let the car run to re pressurise system?

Thanks again,
 
Leave a door or the tail open and run the car for 15 minutes or so as the tank may be empty....

Running it like this will allow the compressor to fill the tank first, then close the door or tail and select standard ride height and see if it is still slow to rise.

If it is, there could be a leak in the system somewhere.
 
If you are now happy with the pressure output. Finger over outlet being forced off it by air pressure. Then remove exhaust filter and with pump running put your finger over that. If there is any air coming out diaphragm is duff.
 
I would suggest fitting a gauge to the system. It really is a piece of cake. Just t into number 6 hose and you will know exactly what's going on.

Number six? Do you mean the Violet coded hose. The hoses are colour coded not numbered.

Hi

according to EAS tech info i have read the system should be up to full pressure within 8 mins & at this point the compressor should have stopped. also if the vehicle was on bump stops the pressure in tank from previous running of compressor will be able to lift the vehicle to desired ride height instantly. If not then thre is most likely a worn piston teflon seal in the compressor pump which is easly replaced, also the pump cilinder gets worn so it is better to replace the piston with cam, cilinder, bottom seal ring within compressor pump all in one & you can get them from ebay cheap. also the valve block seals & pipe o rings are very problamatic & in my case i replaced all of them. it took me about 4 hours to do all of the above including removal & refit pump & valve block into car after taking it in house to repair.

You are correct

BUT

If the guy is starting with the car on the bump stops and an empty tank asking the compressor to fill everything from one run is getting a little close to it over-heating. If you freeze the system by keeping a door open the compressor will fill the tank then switch off. Then closing the door will allow the air in the tank to fill the bags and the compressor can top up the tank. It's the two shorter compressor runs rather than one long one that makes this method safer.
