Putting my GQ on gas and best way

110litre tank under where the main tank goes was my preference when i had a petrol 4x4 GQ.

G'day Kylie,

I had a 90lt gas tank where the main fuel tank is now, then I had a 100lt aftermarket fuel tank in the middle of the car, You need to have a decent fuel capacity as when off road my gas would only last around 200kms, so I needed the fuel as back up. It seemed I was forever trying to get the tuning just right. It was always better on petrol or better on gas, never perfect on both. But go for it as it made the car quite cheap to run around town in.

Cheers Stefan

There have been alot of recent changes to the gas industry in recent 12 months . The gas that we use here in Aust is now allowed to be suppllied from S/E asia this means it is not refined to the standard that it used to be therefore you need to make sure of a few things..1. demand copper lines this will be legislated in the coming year but at the moment they can and will fit the rubber ones. This causes a LEACHING from the rubber resulting in a brown leakage from your vehical ( I only know all this from a 6 mth court battle with a gas intalling company) 2. make sure you get a gas peterol start system this makes it easyier to start .... all I can say is RESEARCH REASEARCH RESEARCH they are becoming a worse industry with the gov rebates on offer they will take your money and palm you off after that. after 6MThs our car is still not running properly my advice save your dough and put it towards fuel...

I have just recently sold my 89 GQ which was on gas. I can offer you some pretty good advice.
1. Being an 88 model it will have a points distributor. Do yourself a favour and install an electronic ignition conversion.(best $$ you will spend)
2. Put 8mm minimum(9mm is what i had) leads.
3. Change the spark plugs.
4. Put an exended rotor button in the distributor.

I loved my GQ on gas and never had any of the problems people talk about with the head. (just make sure your cooling system is top notch) You will use about 23lt/100km.
I had a 115lt usable tank where the original tank was located and a 75lt ulp belly tank which ran down the drivers side under the vehicle.
I had 4 inch springs on the rear and 2 inch springs on the front and never had clearance issues.
Mine was an Impco system and after the installation of the electronic ignition has no tuning issues at all after 50,000kms.
Do the the conversion. With the Govt rebate you will be well in front in less than a year.

Hi

Can I back up the comments about the need to improve the electricals when converting to gas on these older GQ. Had an 89 on gas and constant problems getting it to run properly on gas. After spending a lot trying to get it tuned properly told to fit new bigger plug leads etc but by then was sick of it and bought a diesel patrol. I think this is an option to consider as fuel consumption with gas is very low and no range if you are travelling outback. Also, very few places have gas. If you are all around settled areas probably OK. Diesel is avaiable everywhere.

have fun
