:) morning all

im thinking of trading in my 964.0 v8 for a 95 4.6 hse with gas!!
any idea what i should look for with regards to the lpg system ????:confused:
 
yes you should have a certificate from the installer and some records of safety checks.if it is singlepoint beware they blowback and cause problems
 
thanx i know about certificate are they prone to leaks or any known faults ???

also does the lpg give you cheaper road tax?? :D
 
if it is a diy job leave it. when you view the car start it from cold and see how it performs on gas when warm ie smooth idle smooth change over from petrol to gas you can also check out the installer on line if there is no paperwork for the gas let the seller get a certificate of conformaty at his expense.also it is normal to have a very faint smell when on gas something like a hot dog van
 
Can somebody explain what the certificate proves ? The lpga is the only one I know of and is not recognised by Vosa etc.

I agree. If the car runs OK why the need for a certificate? Do the insurance company ask for it? If they do surely all cars must have a certificate and no one could fit a system at home! So if car is running ok but no certificate, the price for the car would be cheaper and you still save on the gas. Sounds good to me.

The insurance do ask for a copy of the certificate or they won`t insure the car. If a system is fitted at home then an lpg fitting center will check it over and issue a certificate for around £40, but only if it has been fitted correctly.
Hope this helps

I had a Jeep Grand Cherokee converted to gas with a certificate and my insurance company never asked for it so some do some don't.
I am going to convert my P38 4.0 to LPG myself over the next few weeks, I might welll get it checked out after so I can get the certificate but that would only be for peace of mind, as I will be following to code of practice when doing it i.e.the location of the pipes and the spacing of the clips e.t.c. I did notice when I had my jeep done that not all of the guide lines had been followed to the letter.
I do agree about the comments about single point it will drift out of tune and when it does say good bye to your airbox as the back fires can blow them to bits, I had to replace 2 on my Jeep, I then used a cone type filter which allowed the explosion to escape rather than be contained in the airbox.

with respect mate and as eightinavee says the certificate doesnt prove diddly squat other than they have attended and paid for a course and have been given a certifcate to prove it , further more i have never been asked for a certifcate of conformaty.
i also take exception to you suggesting that a diy fitment should be avoided , i have installed my own bigas sequential system and would defy anyone to find fault , especially after seeing some of the so called profesional installations , the single point system that was originally fitted to my p38 was professionally installed by so called professionals and it had a certificate and to be honest it looked like it had been done by a kid , it sort of blows the certificate theory out the water i think.

with respect, diy lpg, particularly by an unknown previous owner is most definitely to be avoided:
Faulty LPG conversion contributed to boy's death, coroner finds. 10/10/2003. ABC News Online
this is not the most detailed report i found but in the interests of good taste this contains merely the salient points. all the children in this vehicle received hideous burns and will be scarred for life and the trauma counsellors are still treating the emergency service workers many years down the track.
i sought and purchased an RR Classic a few months ago and i expressly avoided any vehicles fitted with lpg, even though we have a rigourous certification process in australia.
even the bravest firefighters are reticent to perform an extrication before the tank is isolated. i personally attended an incident where the in-tank iso. valve failed too. i can't remember whether uk uses the same hazchem nomenclature but here lpg is classed '2we'. the 'e' stands for 'consider evacuation' and in the case of service station bullets and road tankers that means an area of 1km around the exposure!
 
i think your missing my point here , i am not trying to say that all diy installations are safe or well carried out , nor am i saying that all professional installations are poor , what i am saying is just because an installation has been carried out by an uncertified installer it does not automatically deem the vehicle as unsafe or uninsureable , i am not that naive enough to believe that anyone can carry out this kind of work to a acceptable standard this is definitely not the case.
whilst your news article is very sad and no doubt totally avoidable i feel it is a one in a million occurrence nevertheless it does drive home the importance of making sure this kind of work is carried out to a high standard and that only the best quality parts are used .
as i said in my previous post i personally would welcome any inspection on my installation , after 36 yrs as an hgv mechanic working on a variety of different fuel systems , air and hydraulic circuits , electrical systems which are a damned sight more complex than most cars i feel i have than enough experience to carry out a task of this nature, fortunately just down the road from me is an lpg workshop with a very good name and i shall be taking my car along to them in the very near future to have a conformity inspection done , this is not because i doubt my workmanship but, just to have the emissions checked and a leak detection carried out , at the end of the day the certificate thats issued is not really worth the paper its written on apart from keeping one or two insurance companies happy :)

This is why I made the comment about the certificate,In Oz you have to be licienced to fit or service lpg kit - on anything.Here in the UK there is no such legislation,and as much as I hate rules and regs this is one area that really needs it.I often have to work on LPG equipped cars and see a great variety of workmanship on the LPG systems - some are awful,nearly all are badly set up.
Considering what a nanny state we live in here in the UK,I really cant understand why it isnt sorted out.(Mind you not all states in OZ even have an annual vehicle inspection so I think they have more immediate problems to deal with - NZ has had WOF for years ! )
 
:) thanx for all your help and advice guys going to pick up new p38 tommorrow got 97 hse with gas will post some pics once ive cleaned it up to my standards once again cheers guys:)
