Citroen XM Forum

OMVL sequential gas injection system for 4 cylinder engines. This is complete with the exception if the injector nozzles I have a number of tanks, 2 small toroidal tanks and a large 90 litre cylinder, although I have no idea of the age of them. £150 for the front end parts with the programming lead and the software, if you want a tank you can take one! You will also have to find the pipe work from the tank to the vaporiser, this is easily found on eBay

Can it be made to run a V6 Stewart??

IE: Is the vaporiser strong enough to do so??

I think the V6 SEi XM auto of mine would benefit from multi point LPG rather then mono point mixer setup..

Im only throwing ideas in the air, the car is a little off any work getting done yet..

As far as I know Paul, it won't as 4 and six cylinder ECUs are different and so is the injector block...

OMVL is a good 'make' of LPG kit...

Tanks are OK if under ten years old. They will have a date plate on them. If older than that they're scrap really. Tank Pressure Relief valves should be replaced every five years.

I din't know this replacement scheme. I got a quote for 2000 euros to put an LPG tank in my 16v. Not worth it in my case. Very expensive so I thought.

Yes, tanks should be replaced at ten yearly intervals or strictly, certification becomes invalid. In practice though I don't believe tank plates are checked at MOT time, only leaks and security so in theory there's nothing to say you should but in the event of a catastrophe and you’re found to have a time-expired tank I guess the insurance will be void.

Mine's 8 this year.

2000 Euros seems a lot Jaap. You can do it yourself at a considerable saving but the problem is to find someone who is happy to certify your work. It is said it is a good idea to make friends with someone who can certify before you start and work with him/her at every step. Trying to find one after you've done the install can be very hard indeed...

Strangely enough, I could legally get away with the certification, according to my 'MOT' man.

I asked him last time we met and he told me he would need nothing on certifications and test the car as presented, meaning running on either LPG or petrol. He was certain of this, and I hold him in high regards. However I still think he might be wrong.
I' love to have an LPG tank though. Even after my first experience filling my first gas tank, ending in my a big gas cloud. Cause: a leaking pipe on a JUST tested car. So much for that test

It's the same in the UK Jaap. No need of a certificate to obtain an MOT pass. All they do is check security and spray a leak revealing potion around the system.

Insurers are keen on a certificate though but not all in my experience.

I still get some childish pleasure out of filling an LPG tank. Both for the cost and for the big pop and gas cloud when you release the nozzle at the end of filling. People tend to look and stare...

I'm afraid not, it is 4 cyl only.. I do have a tatarini ETAgas system that would but that will take some time to find all the parts for it, and it does need more mantanance than a normal system, however I found it was more efficient than the SGI system it replaced
