LPG conversion
as your car already has an injection system, I would ignore that advice and speak to an lpg specialist

LPG conversion
Hi,
My experience with vehicles fitted with LPG, those fitted with later injection systems. IE, after ka\ke injection (93/94onwards) Is that they nearly always end up taking the thing back of again. Not to mention the problems and the cost experienced while fitted. I could tell you a couple of horror stories.
I hope somebody out there can prove me wrong. But it seems to me that they havn't perfected the system for the later cars at all. Well not the mercs anyway. The systems seem to be one fits all. And we all know that can't be right!?!?!?!
My advice, take a GOOD look before you leap. It could be an expensive mistake.
Regards

We run a fleet of LPG vans at work from a major manufacturer (not Merc). We are now taking off the factory fitted LPG kit and retrofitting another setup.
We also do some conversions on cars using aftermarket kits that we have had no problems with, but these are older vehicles.
It would appear that you can't generalise on what will work, and what won't, and that factory fit is not always an indicator of a fully sorted setup.

Hi Niel,
Now you do suprise me. I thought a factory fitted kit would work well. I know MB have experimented with LPG. If any body with a 124 looks at there petrol filler cap. You will find another circle, ready to be cut out. This was for the LPG filler neck. I was led to believe that if fitted from the manufacturer, then the engine would of been made for LPG use. Ie, different pistons etc.
Look forward to any remarks you may have.
Regards
Andy

a friend i work with comes from holland and reckons the kits over there are far superior and cheaper because they;ve been converting to lpg for years.he has had a few cars converted over there and you are right not all cars can be converted ( he had a rover 827 and was advised against it).he says mercs are common on lpg over there ( taxis mainly) and theres pleanty of companys on the net who can help most do a same day service so a quick trip across on the ferry might be an idea!

Ford do have a different engine spec for LPG in some vehicles, basically harder valve gear. Don't know about other manufacturers.
Our problems at work have involved the tanks and float valves, as well as other issues.

New info:
The problems we are having seem to relate to systems that inject liquid into the manifold. The pumping systems required to keep the fuel liquid are the heart of the problem.
Other systems that rely on injecting the fuel in vapour form into the manifold seem to be very reliable.
In theory the liquid injection should be superior to the vapour injection. In practice, the reverse is true.

Thank you to all who replied. After a great deal of research the general opinion from lpg converters is that the vehicle is not suitable for conversion as the engine management system will store fault codes after running on lpg and will cause problems with the vehicle. Have therefore decided to trade the merc and return to shogun !!! Any prospective purchasers please E Mail.!!!!!
