Old Leafsprung Land Rovers

I have all the bits for an LPG conversion, in fact they have been in my possesion for sometime I have now got around to doing the fitting ( residents of the Rhubarb Triangle beware   )

I think I have maybe 50% of how to fit it and need some help with the rest. The kit is Italian - pictchaz  below

Mixer unit with severed connections -

I think the connections are copper pipe from fuel cut off unit and a water in and out rubber pipe connection and petrol in but there should be an out??



Tank  ( is there something missing from the recessed connection here? ) the other 2 connections are from the filler and to the gas cut off solenoid unit



weird french type filler connector that will need replacement



I also have  switch that has a gas and benzene position but curiously alos has a momentary push switch. In addition to the 2 obvious positions it has RV and VV positions

What I'm missing most is a digram of how to wire it up there are -

4 wires  on the switch
2 on the tank which attach to some sort of sensor ( low gas??)
2 wires on the  gas cut off ( is one live to ignition? and the other to the fuel switch??)
1 on the mixer unit also

And that is about as much as I know so far!!

Any help would be appreciated

I'm guessing the push button facility is to switch off all fuels to change over from petrol to gas (ie let the fuel in the float chamber be used) ready to change over to gas.

If you think it's quiet on petrol they can often be quieter on gas!  Yours will be a stealth engine.

Thanks guys and gals

One thing to note is that I got all this stuff  pre loved so there might be the odd bit missing!


1) Tank. Has electrical connections for a LPG on/off solenoid valve and fuel level sender I can see a grey box thing in the left of the tank picture with 2 wires in and out this looks like the cut off
2) Petrol solenoid valve. This is inserted in the fuel line somewhere to shut the flow of petrol off when the gas is flowing, and vice versa. I don't seem to have one of these but no probs I don't think they will be expensive
3) LPG solenoid valve. Both of mine have an extra gas on/off solenoid valve just before the vapouriser Yes judging by the the pipes used that is where the LPG solenoid valve fits in
4) Vapouriser. Has yet another LPG solenoid valve(!), inlet and outlet for coolant water, inlet for LPG (copper pipe), outlet for vapourised LPG (rubber hose)
5) Power valve. Sits between the vapouriser and the mixer to adjust gas flow RIGHT!! the penny is dropping mine came of a V8 so there are the valve is a y shaped to each bank of 4 cylinders!! so presumably I will need another one or just put the 2 back into 1 with another Y connector?

6) Mixer. Sits on top of the carb or in the inlet hose missing this bit are they universal?
7) Switch. Both of mine have three positions, LPG, off, petrol. A wiring loom should come with the switch, it's dead simple to connect up.  No wiring loom but I'm sure I can sort something out once i get my head around the connections


There's likely a fuel cut off solenoid on the tank and the vapouriser, both probably on a blue? wire Found what I think is the cut off valve on the tank balck and red connections
Yello to the petrol shut of solenoid This bit is missing!!
Red power +'ve take from +'ve coil connection is good
black probably earth
grean - fuel level sensor


Vapouriser should have water in/out, high-pressure gas in and low-pressure gas out to a mixer (bolts under the carb).
tank will have in from filler and out to vap. Right that is useful the petrol valve is separate! I have a better idea now!

You can get adapters for the different fillers. Yes I'm hoping the filler pipes are universal so I can just screw the UK type on


I manage to get the tank mountings in the back bolted through the floor supports I will have another fiddle tonight.

Thanks for the comments and help

Silent and Cheaper Leafing is on the distant horizon

You'll probably know that it is necessary to mount the tank so that the orifices are at circa 70 degrees rather than at the top. (it is to allow for expansion so that lots of gas isn't vented in hot weather.)

What it means in practice is that a (for example) nominal 80 litre tank actually accommodates around 60 litres of gas.

No probs, I'll get 'em in the post today.

The tank angle can vary between manufacturers, it's usually stated on the instructions with the tank (that you obviously won't have). The tank should have a plate on it showing manufacturer, size, capacity etc. If you Google that you'll probably find some info. 70 degrees is fair enough to say but can be harder to work out accurately, they'll usually have a distance in mm from the bottom of the tank to another point of reference such as the gas tight box, valves etc to make it easier in the instructions.

Mine is 80 litres and fits tightly crossways. Certification is dependent on getting these details right.

After some activity back in July it all went quiet I have the take fitted and the mixer installed and the LPG cut off solenoid and then holiday and new bantams and allotaments full of veg and that other evil work  got in the way  back on the case now!

Whilst on the verge of ordering all the bits I'm short i.e.  3.5 metres 8mm pipe, Petrol cut off solenoid and a UK compliant filler that will fit the JIC type fuel inlet hose to the tank. ( spending money scary for the Yorkshireman  )

I then discovered that the pipe flaring kit had a bust 3/16 dye so I need one of these



Just need to order a pack of 8mm olives from ebay then hopefully will be able to get  to the bit where I try to wire it up!!

Don't hold your breath
