I used to know a guy who ran an MG Midget in Prod Sports where the regs stated he must run 'pump' fuel. The scrutineers got a little upset when they found the pump he was using was the Avgas one at a local airfield.......

One of my varied fleet had a mechanical diaphram type fuel pump with a restricted return on the inlet to the carb to allow excess fuel delivery back to the tank. The pump started to leak (directly above the exhaust manifold!) so I decided to do a mod. If you think about it, the cam driven diaphram p...

The old turbo diseasel in the Land Rover is 'tired', so I'm toying with finding the bits to convert it to petrol but keep the turbo - gassed of course. 11:1 comp ratio should make it reasonably pokey :D Oddly enough I had exactly the same thought when I first saw that chart..... That coupled with f...

If it was a Stefanelli system I'd have expected everything to have been made by Stefanelli but their website ( http://www.stefanelligroup.com/ ) shows nothing like you've described. See if you can identify any of the other bits from the AEB site at http://www.aeb.it/products .

Ross, Matt and myself have spent half the afternoon doing diagnosis by telephone (I've got a stinking cold so it stopped me sitting here feeling sorry for myself)! He's got a very simple early system (OMVL Lynx) that is all working as it should, when it works! It will only switch over to gas sometim...

Matt. now we've talked it through, the system you have fitted is in this document on page 11 http://www.vogelsautogas.nl/documenten/Techniek%20OMVL%20Nederlands/OMVL_Catalogus_02_Installatieschemas.pdf . It looks like whoever installed it fitted an additional relay in the solenoid feed to prevent th...

Doing a bit more hunting around, if you've got a kit originally intended for a carb engine, the controll may be incorporated in the switch. In this case, there will be quite a lot of wires going to the switch rather than the usual 4 thin ones.

Well here's the complete Millenium installation http://www.omvlgas.it/eng/prod_detail.php?id=59 although that shows a slightly different design switch. For yours to only switch sometimes but to do it when it is supposed to do, means there has to be a controller in there somewhere.....

One of the wires will be an earth connection the other will come from the controller. However, the same feed will also go to the shut off solenoid on the tank so it is always possible that someone has wired that one from the tank forwards rather than direct from the controller. How about tracing the...

Yes, you've found the solenoid, now you need to find the box that has the relay in it that you hear click when it changes over. Follow the wires from the solenoid and see where they go. Once you find what they are connected to, you'll have found the bit that deals with the changeover.

The vapouriser is the bit that turns liquid gas from the tank into vapour gas that can be supplied to the engine. It will be on the end of the pipe shown in your last picture. The other end of the pipe goes to a mixer fitted somewhere in your intake trunking. The vapouriser will have a filter (proba...

Up until the last picture I was assuming OMVL Millenium...... Maybe someone has dumped the stepper and replaced it with a manual power valve. Is there a controller for the LPG lurking anywhere? Try tracing the wires from the solenoid on the vapouriser to see where they go.

The simplest, although not the best, way of setting up an open loop system is by ear. Ideally you should do it with it on an exhaust gas analyser but if you work on the principle that it'll work best if the mixture is correct you will get it pretty close. With the engine at normal operating temperat...

The only additive you can use on an LPG car is something called Flashlube. This is an oil that is injected into the intake and is to lubricate the valve seats and prevent regression. The jury is still out on whether it works or not and some cars don't need it, the valve seats are sufficiently hard t...

You may not actually have an ECU as such. You mention that you have a "big screw on the pipe to the regulator" so you could have an open loop system. This has a manual valve between the vapouriser/regulator and the mixer rather than a stepper motor controlled by an ECU. For an explanation on how it ...

While I would never try to put someone off doing a conversion, in fact, I'd encourage everyone to do one, but I have to ask why.
