Hello!
I'll give you an E-Mail Adress, which you can trust in his competence really. (Sorry because of May terrible english)
His name is Wolfgang Vetter near Mainz in Germany:
(wolf_vetter@web.de)
He is specialist of liquid injection systems like Vialle. Of course Vialle is one of the best systems in the LPG Business.
Why remove?
Nur mal eine Vermutung: Kann sein, daß er die kaputte LPG Anlage abgebaut hat - und will sie hier in Deutschland - sozusagen aufm Festland - reparieren lassen und wieder nach GB zurück bringen. Ich weiß nämlich von Anderen, daß in GB die LPG/CGN Reparatur unheimlich kostenspielig ist, so daß sich der Aufwand trotz allem lohnt..! Ich hätte auch die Vialle abgebaut, anstatt dem Auto hierher zu schleppen. Man kann allerdings nun argumentieren, er hätte ja die Anlage dran lassen sollen und im Benzinbetrieb hierher fahren... Keine Ahnung! Wenn kein LPG Fahrzeug vorhanden ist, käme für eine solche weit über 1000 km Strecke vom britischen Insel hierher dann halt ein Selbstzünder in Frage..!

Hello
thank you mawi2006 for the link but it didnt helped me.
Why a want to remove LPG form the car? Becouse its worn out, it worked for 200kkm but nov lpg pump is dead (vialle program said that pump have to litlle rpm) and the vialle know sometimes turn od led, sometimes not so, probably 2 injectors aore poor in working so ive decided that its not economicaly to repair those things couse new pump is 600eur and 1 injecor is 200eur and i dont want to service old system its than better to buy new one for 2000eur and thats it but iv decided that i dont want to have LPG in my car.
As ive seen its not complicated to remove instalation. I need new air intake becouse of holes where injectors are, gas tank i dont see any problems with removal just i need a correct procedure to let out remaining gas from the tank for safety removal of the LPG instalation.
#2 second thing is i need answer if viale cpu is only bypassed with one wire if i saw correctly to car dme/cpu and when removal i need only to rewire that wire directl to dme/cpu of the car?
Other things i dont s problem. Pipes to lpg is easly removed, also lpg connector for puting LPG in the tank and so on
I was hoping to read something by ICOMworker wich i saw its vialle expert
Why not? because, it is in german?
You can mount a hose at the system, may be, vialle tank ist different, is their a pressure regulator by the engine? On a Icom gassystem is a connection for pressure measurement.
The open end of the hose should be a few meters away in an open area without sinks and gullies. Avoid fire and sparks.
It will take some time for the tank to empty. Then you can also open the tank, as only residual gases escape, it will not be completely empty yet.
I think the Vialle cuts off the gasoline nozzles, this break has to be reversed.
..or you let the Vialle Unit in the Car and remove tank, injectors ...

Yes i know that, thats why i asked. I saw on the schematics wiring diagram that one or two wires from car computers are cut off and than bypass its made trough vialle cpu unit, i think this is easy to solve i just need to rewire those two wires.
Viale injectors also are easy to recover from airintake manifold.
Main problem for me is to empty residual gas from tank, couse i want to se some manual step by step to be sure i am doing right thing.
No Vialle technican here to help about gas in tank?

You can close the valve by handscrew and remove the tank out of the car. Then you can go on a free field and loosen the screws that hold the whole assembly in the tank until it starts blowing Gas out of it. DONT SMOKE DURING THIS OPERATION and also there scholud be no fires in the surround.(free field). It migt take one hour or more to empty the tank,. thats a question of the amount of Gas inside the tank and the amount of gas thats blowing out. After all you should disaseable the plate fully. By this it would blow out the rest of Gas. Store it outside of buildings for at least 3 days before you deposit it inside of a building or take ist to the junkyard.
Good Luck , and be careful

Ich sehe da nur keine Rändelschraube, sonst hätte ich bereits was dazu geschrieben.
Uns was ist mit der Rückleitung?
Hallo Mawi
Die Rückleitung muss auch ein Rückschlagventil haben. Zumindest habe ich eine Icom aus einem Auto ausebaut , und das ging bei 20% gefültem Tank ohne dass mir das Gas um die Ohren gezischt ist. Kann sein dass da kein Handrad war , das weiß ich nicht mehr genau , aber die Magnetventile müssen ja stromlos auch dicht sein ,

I understaind last part of written post. But i dont know which screw is for closing lpg from tank, and if there is screw that is for closing i assume that the same screw is for letting out the gas also?
About residual gas in tank i let the car working on gas till reserve yellow light pop up on Vialle knob and lpg was automaticaly switched back on the fuel couse gas tank was empty but in thank as i know some lpg gas stays inside gas tank? Its not 100% empty yes?
When i will have tank outside from the car than i will unscrew al 6 screws and let gas out and let it outside of close rooms to ventilate with fresh air. But i assumed that for letting gas out of the tank that there must be some screw for this task but i dont know which one.
Than when i will unmount lpg hose from injectors the gas inside hose will parish. But gas inside lpg valve will bi present inside , but as i see that this hose can be easly dissasembled from lpg valve there will be no problem about it i think?
Gas inside hoses form tank to lpg valve this is another story couse the lines are 2m long, but also when disconecting from tank ang lpg valve at engine room i think the gas will parish.
Hello...
I looked on a picture in Lpg forum .
There is no closing screw in the system.
But the system is glosed by the solenoid valves.
You can open the hoses in the engine compartment a little an let the gas in the lines escape.
Then you can remove everything of the gassystem from the car.
After all you might do the shedule with the tank on the free field.
There s no screw to evacuate the gas from the tank.
