As it happens, there are light aircraft running on LPG I believe - I've been told that it's not sooo uncommon in France. In the UK, I'm sure our CAA can price the regulation of any modification out of the question :cry: I've seen a sheet with the requirements, and it's not that onerous - but I don't think many of our multivalves would pass the "runs without electricity" requirement.
But the weight of steel tanks would be a serious penalty in most light aircraft.

Had my cat plugged into a mates diagnostic laptop the other day, and was getting a 'Rear bank running lean' warning on the laptop, although it wasnt bad enough to issue a fault code on the dash menu. It gave the reason as being the secondary throttle not closed properly. My friend and I came to the conclusion it may be a small inlet gasket leak, caused by the backfires. :?
Any thoughts????
I may just replace the gaskets anyway, but its about £50 of gaskets!!!!

True but with the dodgy gaskets (if it is that), it will cause your mixtures to be leaner anyway which is not always great news.

Still, looks relatively tidy, but I echo the comments of Rossko considering that I owned an XJ40 XJR with a Voltran Single Point system. But at the end of the LPG like other car related things is a game of compromises.

Well still havent had a look at the 2ndaries (finding time!) but have fitted a 57i induction kit, yes i was told i might have issues with it, but hey, i have issues anyway, so what did i have to lose! As it turns out, it was a darn sight easier to set up than with the airbox, yes i am having to run a tad richer, but then again, it does suck in a helluva lot more air!!! Also when it does backfire (less frequently now) it dont blow the airbox apart!
The other issue i have is that the level sensor is giving me vague readings, sometimes its ok, but others, it just tells me i got a full tank when i know i havent!!! (see pics above for which type)
Anyone had this before, if not, then i got to do a tank dump!! which i'd rather not

Shouldn't back-fire with a sequential system .........you got ignition problems that need to be sorted ..

The electric level sensors never work right ..

When I fitted my system ..I had read so much bad @!## about them ..that I never bothered to buy one ....waste of money ..
I set the speedo trip meter to zero and fill up every 250 miles
My 80 litre (59 litre). tank has range of 270 miles to 400 miles ...depending on short trips or long trips............I've only ever run out once on this car in 12,000 miles on lpg...that was when Morrison's pump was broken down the other week ...

all the best.mark

Cheers mark, but its a single point, with quite a few limitations on the install, due to lack of space etc in the engine bay, so an optimum fit wasnt possible, hence the backfires. The level guage has been good enough up to now, so something has gone awry somewhere, will have to do a diagnostic on the electrical side before i remove the valve thats all, was just wondering if anyone else had had similar issues.
Also i get up to 55l in my 66l tank, so it cant be that bad, but i use the trip also, and get 190 to 250 on a tank

Cheers Ross, but my earth goes all the way forward and links up with the rest of the loom and is earthed under the bonnet on the bulkhead, so if one goes surely the whole lot will. Will chase some wires over xmas, but am still thinking its to do with the mechanical side of things (ie magnet or level arm, or maybe just come away from the housing a tad enough to lose the magnetism)

Latest part of the project is to fit an ST200 Inlet Manifold and throttle body, may have to get a new mixer to fit the larger TB but will update onse i done it

Have had some issues with the cat re clutch and gearchange, so while its in bits have been fitting the ST200 additions, just need a larger mixer to suit the throttle body.
Just a note to say that i have had less issues with backfiring since i fitted the 57i than with the standard airbox, will post some pics once its all finished

No spuds on mine, its single point, but there is pics of someone elses earlier in the thread.

Have bought a mixer to go on my ST200 throttle body (Upper and lower ST200 manifolds already fitted) but need to measure up when i swap cos it looks like same size mixer insert!!! :?

It's meant to, it's the mixer and it works by acting as a venturi to speed up airflow through it to draw the gas in.

Well it turns out the ST220 TB doesnt like the setup on my car!!! Bloody typical :evil: even removed the mixer, swapped the TPS and the MAF, checked the Intake temp sensor too, but it just dont like it!!!! Gives me a massive flat spot in the mid range and top end on full throttle, theres been a few guys on UKC that have done this mod and have not reported any similar problems, hell i even swapped a duff O2 sensor on the rear bank!! (showed up on the laptop) did a diagnostic run using the laptop and the power just disappears @ 3k and 5k, so its either a remap or back to old faithfull lol bugger! :?

Deffo not IMRC John, have put the standard TB back on and its fine, go figure, the only thing i can think of is that the 57i thats fitted along with the larger TB is allowing too much air in, in other words without a full remap it aint happening, so its staying with the standard one for now, cos i cba to chase what dont need fixing lol :lol: :lol: :lol:
