truth needed about LPG
sorry to start a new thread on this but I need answers on this one...

but i've only done single point injection and carb.
I would really love to know who to get this conversion, not just for my 7 but my other carb cars. I went to a place in Peterhead who is suppose to be
the expert and was told it was simply not possible to get a carb car converted, much to my UTTER dismay and confusion.
Yet I was told at the same time (by reliable sources) that the Landy folk were chucking their diesel and putting in V8's instead and running
LPG!!?? but I was told...??
I was also told that I would NOT get insurance if it wasn't signed of by a corgi inspector...
If all that I have been told is bo££%cks please let me know cos I wanted to do this years ago and have been bit$£ing about it since.
Oh yeah just to rub it in at the time I was driving a fork lift powered by a Toyota petrol engine running on yes LPG aaaahhh!

you can fit lpg to almost any vehicle petrol turbo diesel piston or rotary
you do not have to be corgi registered but it is advisable to get it checked over by a registered fitter to enable insurance to be satisfied that it
is safe

damn.
does anyone have a source of parts, even a diagram? Can I just use a standard bottle as the tanks look quite thin?
Cheers.

and how are you going to refill a standard bottle ?
a correct lpg tank is tested to a certain standard they come in either cylinder or donut shape

its bo££%cks
Yes you can convert cars with carbs, you use a vortex system, ie a ring bleeds gas infront of the carb, its how all LPG systems worked before
injection.
I suspect this would be pants way on multiple carbs, good one or two.
It is however subject to backfires.
The next generation 4+ years ago refined this system for injected cars, the vortex ring sits infront of the throttle body but you include an electric
regulator to meter the gas flow to the vortex ring wuch goes to a simple ECU which reads revs and lambda sensor to optimise the system.
Todays systems replicate petrol systems but use gas, typically piggy backing on th cars ECU to simplify install.
I have converted cars using all three systems, have never been asked for a certifcate of compliance (insured with Norwich Union) although did ask if
they wanted one.
Even then it only costs £50 for a certified engineer to inspect and sign off on.
What are you converting ? I have an old gas regulator (good for large V8'S 5.7l)and vortex ring for a 3.9/4.0/4.6 EFI V8 rover engine you can
have for a drink + P&P
Removed because I upgraded to a full EFI when I changed cars and kept the tanks etc.

A big thanks Mark,
cars needing converted are -
Bluey one - 1.8
Bluey two - 1.6
Buggy - 1.6
Falcon - 2.0
Corolla - 2.0
Vectra - 1.8
& not forgetting the 7 - 2.8 ish
Unfortunately it sounds like the rings you have are a tad big for me to use, but thanks for offering. The blokes who told me all these lies in the
first place made a big point of the backfires claiming that manifolds had exploded like hand grenades!!!  I was a bit taken aback by this since my
Cortina was for ever backfiring, even once burning off my eyebrows!! (don't look down carbs and rev the engine, safety tip there...).
As for the cylinder I don't see a problem since the filler doesn't go into the tank and would just be connected by pipes just like any
other.
I thought the insurance problem would be insurmountable, obviously not and was the reason I never pursued it further. I think I gave up to easily

Try www.chrisperfect.com, or www.gordonfinlay-lpgconversions.co.uk for diy kits.
Tanks are available in any dimension imaginable.
I had my disco converted 3 years ago, it was done by pressland autogas (www.presslandautogas.com), it is a multi point injection version. I have never
been asked for any certificate, which i do have, from any insurance company.
It also hasn't effected my premium.
The fogger system (rings) is also used on injection systems, a popper valve is fitted in the air filter in case of explosions! i have yet to see
one!
The savings are really good too, the most i've ever paid is 43p a litre.

Macnab, I know a really good and cheap installer in Edinburgh, G.A.S. Autogas. They did my Rangie and it has been a really good investment. There is
no bullshit here but the guy who runs it, Spas, is really knowledgeable.
Carbs are easy to convert using the appropriate venturi system for the carb and manifold. The backfire problem occurs with single throttle EFI systems
using a venturi gas system, the plenum box can be full of an explosive mixture of air and gas so if you get a backfire it can ignite explosively
resulting in a burst plenum and usually destroyed air flow meter. Spas recommends sequential multi point gas systems for all EFI conversions but has a
good selection of venturis, evaporators, tanks and controls. U2U me if you want his contact info.

Hi
we heat our house on lpg which is a real rip, we have managed to get the price down to 25p / litre, due to strong negotiations, though Shell would
like us to pay much more, I read somewhere of a guy who got a nozzle installed on his own bulk tank that would be cheap motoring!!

Dads boss has LPG installed on his V8 landy that he uses for off-roading in. The backfires it causes when not running right have to be heard to be
belived, I can well imagine that plastic manifolds would shatter.

In the 80-s I worked as a mechanic maintaining a fleet of Transits and MK2 Escort vans for a large firm. They had their own LPG station and fitted
their own LPG conversions. They were comically simple. A tank, an evaporator and either a sandwich plate in the carb, or just a hose running into the
plastic airbox !
I never saw any new LPG equipment, it was just taken from the old vans and fitted to the new ones, the boss used to set the fuelling by smell

well guys, that's all been very helpful.
Looks like its a goer, I been speaking to friends now about this and all are well impressed. Especially since I had told them it wasn't
possible
A popper valve under the level of the carb does sound a good idea but all my cars have ally manifolds so should not explode!! he he
I'll have a good look at this and I think the first to convert will be one of the Blue birds since their simple and have big boots. I think also
I'll take some pictures to show the process to help others.
Filling from the central heating tank is a good move, hell I might just fit a jag v12 in the locost!!
Caber if you could send those contact details it would be great, I’d send you a utu but the damn things not loading up for some reason…
Right got to go, hang on I’m sober!!! 40 mins to get blootered will I make it???
Happy new year!

I was toying with making my middy a dual fuel car - my twin tanks would have been ideal. I chickened out though as I was worried about tank damage in
an accident - it's bad enough having 50 litres of super unleaded under your elbows, let alone having high pressure gas
I would imagine the Nitrous Oxide kits might be a source of some suitable hardware for LPG (foggers, solenoids etc)
Cheers,
Raz

If you are seriously going ahead it would be worth contacting the guy who used to be the technical secretary of the jago owners club - he does these
conversions for a living in Staffordshire area and has 2 Jagos on the road using lpg , one of them is 100% lpg fuelled - no petrol tank etc. He has
had some problems convincing the DVLA that his car does not use any fuel other than lpg - apparently theydon't appear to have a tiock box for
this option!!
I',, digdetails out later - I'mnot sure ifhe hasn't produced some guidance to help others to get through the project without
contravening any regulations

It's been agreed that one of the bluebirds will be converted, had big discutions last night about all this. There's a DIY kit I like the
sound off. Bit pricey mind at aprox £1200 for the kit, but I'm looking up how much of a grant you'll get from the govenment. Sounds
great.
