Just a thought... Where does the coolant hose which runs accross the fron of the engine bay on a 3.0 go from/to? Could thais be interested to feed the vaporiser?  :question :question :question

AFAIK the reason this pipe is NOT used is it is "outside" the engine/thermostat loop .. ie .. it only gets hot once the thermostat opens. By having the vapouriser "inside" the loop it heats up very much faster, so switches from petrol gas earlier... mine is taking less than a mile at the moment, although I expect it will be longer in the winter.

Any idea of cost? Hatching a plan


It was £1850 + VAT  (£2173.80)  .....  :(
With the cost of fuel these days it will not take long to get that back, Is this a multipoint system?
I have a LPG kit in my garage which has seen better days but it works, but it's not currently attached to a car at the moment. I have a tank the same as yours as I think the bigger the tank the better and also with the other type of tanks the bigger one's usually sit higher than the base of the boot and you have to sort something out to level the floor of the boot which is just a pain more than anything else.

That looks a lovely install.

Looks nice and neat. I take it they have treated the hole they have cut to prevent rusting? I think a can of touch up paint wouldn't have gone amiss on the filler but I've heard that the paint rarely stays put for long so probably why they don't do it!!

Got to do mine now... Although seeing the job they've done of yours I'm tepted to save myself the hassle and get them to do it!! (Note to self: Remember the savings of a DIY conversion!)  :y :y :y :y

The guy actually said  that if it was sprayed it might last 4 months !! His opinion .. and I tend to see his point ... window surrounds are black, door surrounds are black, tyres are black .. it does not look out of place if "lined up" correctly ..  :y :y

Mine was still in mint condition 6 months after i did my install, and i was filling up 4 times a week....

IT's all down to the paint used and the time taken to do it, yes you could blast some champagne paint on there let it dry and it might only last 2 mins, or you can build the paint up, keep it nice and warm and make a really good job of it.

Some very quickly taken piccies as requested ... I'm no David Bailey !!

Filler, looks OK, lines up nicely and is accessible at all times.



Filler from the inside



Tank, very neatly installed



Control switch - crap photo actually looks very neat



Engine bay overall



Left hand bank with pressure regulator, the "spare" plug is a pressure test connection for the diagnostic kit



Right hand bank



Filter



ECU, beside the pollen filter



Flash Lube kit



No pictures of the vaporiser I'm afraid .. its buried down behind/below the passenger side headlamp !! The vaporiser water pipes go right around the engine bay and connect by the HBV, but on the engine side not the heater side !!.

To my totally untrained eye, it all looks rather neat.... and it all seems to work !!



Just a thought... Where does the coolant hose which runs accross the fron of the engine bay on a 3.0 go from/to? Could thais be interested to feed the vaporiser?  :question :question :question


Nope - need feed from behind the engine

Looks like BRC, but not the latest Sequent. Is it “FAST”?  Now, they’ve moved temp sensor from the rail and it’s in vaporizer.
I must say that the split from the vaporizer to injector rails is not the best idea. Might not cause any problems but better to have an eye on that. Gas have to flow easy at the same pressure and without any bends to both heads. This way left head will get more pressure than the right one (gas is redirected by ca 300 degrees to the right one while left branch is almost straight. Flow to the straight line might cause suction in the right one) and you may have problems with the engine running on high revs.

That black box – is it connected to the vaporizer or the manifold? I have BRC Sequent 24 (MY07) and there is only P1 sensor connected to the vaporizer, there is no MAP sensor and any time I would like to reset it, I have to go to BRC specialist to do it… I would take it away from the rail as it gets hot and might damage the sensor.
BTW – you don’t need a valve saver – it’s only to get more money from people. All valve seats are enforced and are strong enough for LPG. How much is it for bottle now? How long does it last?

My 2.6 was converted when I bought it, my 2nd gas car it has the 70 litre "donut" tank that takes 60 litres and does about 17 mpg and 180 miles on a full tank around town, on a run I get about 25mpg so about 50 mpg after conversion. :y

Mine (2.0 auto) is doing 28MPG on the long run, 21MPH when I drive to work (Reading –Basingstoke), and ca 16 in Town. This is real consumption, not from computer.
So, when commuting to work, I can do 160-170 miles on 37l tank.  Not that bad, but could be better. I also found that sometimes consumption is very good, and suddenly it goes up. Don’t know if it depends from the LPG or any sensor is fouling ECU.

Sorry for the delay in responding ... was away for the weekend  :)

I'm VERY pleased with the conversion, it is saving me, at the moment 10.64 pence for every mile travelled (23.48 pence/mile calculated petrol cost, 13.20 pence/mile actual LPG cost).

Done just over 600 miles, and it has not affected performance at all, even when towing. Solo I'm getting 300 miles to a tank of LPG, towing is estimated at 200+ probably .. not done a long enough journey yet .... The lakes meet will sort those figures out !!!

The boot space is reduced of course, but 90% of the time the boot is virtually empty, so matters not :)

I did have to do a major re-think on weekend packing, and ended up with laptop/camera kit/coats on the back seat. Worst PITA is i have to take everything out to put the solar panel flat in the boot, then pack everything back up, reverse that to actually use the panel... but I'll get used to it.

Would I convert again ??? like a shot.
Same company ?? certainly.
Same system ?? probably

HTH  :)

The conversion looks very neat. On my 3.0 Elite estate the injectors are just laid out across the top of the plenum, a bit untidily. Also, it was done a few years ago (2001 I think) so I expect things have moved on a bit since then installation and design-wise.

a very neat and tidy install, i like the position of the switch in the centre console.

i only wish some one could come up with a bracket to place the injector solenoids on the side if the air rams as this would ensure even pipe lengths for each bank and aid us DIY ers!
