Converting an Existing Vehicle

What types of cars can get converted?

Almost all unleaded petrol-fuelled vehicles can be converted to LPG, subject to space limitations. Large sedans, utes, vans, station wagons, four-wheel drives can all be converted. CLICK HERE to find your nearest installer who will be able to advise you if your vehicle can be converted to LPG.

How does my car get converted?

A steel LPG storage tank is installed which is manufactured to comply with AS 3509 and installed to meet the stringent safety requirements of AS 1425. This tank is usually installed in the forward part of the boot but it can go under the floor in vehicles with enough clearance, eg 4WD’s. New equipment is added to the vehicle but very little of the existing equipment is changed or removed. All conversions will, however, include a dedicated gas fill point.

You can choose between having your vehicle run solely on LPG or both LPG and petrol, which is known as duel-fuel.

How quickly can I get a conversion done?

That will depend entirely upon the chosen AAFRB Registered Business and their work load at the time. With the introduction of the Government rebate interest in installations has significantly increased so some sort of waiting period is expected with most installers. CLICK HERE to find your nearest AAFRB Registered Business who will be able to advise you of when a conversion can be done.

How long does a conversion take?

The installation time will vary depending on a number of factors including tank options, the number of cylinders, position of the tank etc. A typical family sedan with a single boot-mounted tank should take approximately two to three days. While a large four-wheel drive with multiple tanks might take up to a week.

How much does a conversion cost?

This will depend on the type of vehicle to be converted and the licensed installer you select. Typical conversions can range from $2,000 to $4,000 and will also depend on whether you choose to have your vehicle run solely on LPG or both LPG and petrol, which is known as duel-fuel. Conversion to duel-fuel is more expensive than LPG only.  However, this cost can be quickly recouped via the Government rebate and the savings made at the pump every time you fill up. CLICK HERE to find your nearest AAFRB Registered Business who will be able to provide you with a quote to convert your vehicle.

Service and repair of LP gas vehicles

Always follow the vehicle manufacturer’s as well as the LPG Component suppliers recommendations on periodic / routine servicing of your vehicle. As all LPG systems rely on the engines cooling system it is important that the engines cooling systems be maintained in a serviceable condition, including checking the coolant level on a daily / weekly basis. LPG requires a slightly higher firing voltage than petrol, it is recommended that the vehicles ignition system be maintained to a minimum of the vehicle manufacturers specifications.

LP Gas Fuel System Maintenance

For the safe and reliable operation of the LP Gas system fitted to your vehicle always ensure that repairs are carried out in a AAFRB registered workshop by an AAFRB accredited installer. It is recommended that an inspection be carried out on your vehicle’s complete LP Gas system as part of regular servicing or at least annually by a licensed installer. In this annual inspection, the following must be carried out:

  • All the gas systems fuel connections checked for possible leakages.
  • The LP Gas convertor checked for any “residue” content and serviced if required.
  • The fuel container needs to be checked for its date stamp (a fuel container requires re-inspection, replacement of the pressure relief device and re-stamping the test date every 10 years.)
  • The fuel containers attachment requires inspection for looseness and metal fatigue.
  • The LPG cylinders Automatic Fill Limiter should be checked for correct operation.

Petrol Fuel System Maintenance

As your vehicle will operate mainly on LP Gas, the petrol side of the fuel system will require certain precautions to be adhered to:

  • Never allow the petrol level to fall below a quarter of petrol tanks capacity.
  • Always use a minimum of 10 litres of petrol per fortnight. This will ensure that fresh petrol is always available. A fuel system cleaner (eg FUEL INJECTOR CLEANER) should be added every six months to your petrol fuel system.
  • On a carburettor engine it is recommended that once a fortnight, the engine’s carburettor be filled up with petrol and left standing overnight. This allows petrol to soak into the carburettor’s gaskets and seals.
  • Petrol fuel system components should be checked regularly for serviceability and deterioration of flexible hoses.
