How much gas do you need to carry, I assume you fill up each time you fill your tank. The sill tanks seem a good way to go. Would they protrude much from a D1?
What happens if you run out of gas or can't get any?
I would appreciate if any one could answer any of these questions.

When I looked into it a couple of years ago I was told that it runs like normal without the LPG.

Will this fit my series 2 disco and does anyone do it in perth.

Anyone got pics of a series 2 Disco with sill tanks?

Whats the consumption like with all that extra performance same or better ?

Last I checked it was about a 1:3 ratio - the gas tank only needed to be about 1/3rd the size of your diesel tank.

You don't need to fill your gas tank up each time as such, however it doesn't hurt. If you run out of gas it's no big deal, the system just switches off and you go back to running as a normal diesel engine - yes this can (apparently) be done on the fly. There is also a switch that lets you enable / disable the system from inside the cockpit (if, for some reason, you wanted to disable the system).

Dont' think the sill tanks would protrude much from a D1 but can't say for certain, in an equivalent Defender they don't protrude at all...

I can assist about the sill tanks. Yes they do protrude on the Disco, same as the Range Rover classic. The height of the chassis rail is about 150mm and the smallest diameter tank that APA manufacturing will currently make is the 203mm size the same as the manifold tanks. With the supports and a protection plate it will hang about 60-70mm below the line of the chassis. This is not a problem for people with a 2" body lift, but is a concern for those of us who haven't.

The 203mm tanks are made as specials by APA and will hold nearly 20 litres of LPG each. They can be connected with a single filler connection.

Hope this helps.

Just out of curiosity, How much has the cost of these conversions gone up since the gov subsidy came in. It just seems to me that the price has gone up substantially which to my mind means the subsidy is going to the installers not the customers.

The ones making the money are the manufacturers and component suppliers, they get effectively all of the Government money and the installer gets some of the remaining price.

my brother in law has recently{within last 12 months}had this installed on his disco and seems quite happy with it

I've been doing some research on these lately, but good tech info is hard to find. Most articles promote the benefits, but don't explain the process.

I've so far come across theses systems

Eco-shot - the LPG is drawn out of the cylinder as a vapour, hence no convertor required. It is drawn into the motor by a small valve that is controlled by turbo boost. Only suitable to turbo diesel engines, very compact, no hot water plumbing, but still expensive at $4,500 or there abouts.

The system hymie got from the guy in Warrugul. Again the LPG is drawn as a vapour from a 4 valve tank (more expensive, but cheaper to re-stamp) and using an Impco type J convertor. Goes in just before the turbo, no computer control again, not regulated by boost though. $2,800

The Dieselgas system as featured in 4WD Monthly, computer controlled. $4,600.

Any one got info on pros and cons? Risks? and tech info on how they work.

Thanks.
