Holden Rodeo 3.2 with an Impco Airvalve system.

System type: Under bonnet we use an Impco airvalve system as the most suitable and durable equipment to fit to this application. This has an automatic petrol start and is a closed loop system using the car's exhaust oxygen sensor to feed information back to the gas processor to control the mixtures.

Cylinder: with the Rodeo the cylinder size depends on the location of the cylinder and this depends on the body style of the vehicle. The single cab tray body can have a cylinder mounted in the centre of the vehicle on the other side of the tail-shaft from the petrol tank and the exhaust system is modified to clear the gas cylinder. The spare wheel can then stay where it is. Generally the cylinder will be 70 or more useable litres of LPG.

Twin cabs can have a cylinder under the centre too but it is quite small and only about 48 litres of useable LPG. Most people opt for the tank under the rear as for the utility bodies.

Utilities (all bodies) get the cylinder under the rear where the spare wheel is and the exhaust tailpipe is modified. The rear tank is 68 litres of useable LPG.

On a twin cab or extra cab with tray we can often get the spare back under the rear as well as the gas cylinder. This depends on tray size, type and towbar.

Location: rear in lieu of spare wheel or centre mount with exhaust modifications; see above.

Controls: A unit combining the changeover switch and an LED gauge is fitted into an existing switch blank on the dashboard. This integrates well into the dash.

Filler: On utility bodies we generally go in the rear adjacent to the number plate and on tray bodies we fit the LPG filler near the petrol filler to have them on the same side.

Disclaimer: We endeavour to get all our data correct but we do not guarantee that we are perfect and haven't made an error in some of the data.

With the injection systems we do change the brand we use where we can improve on the quality of the equipment fitted. We are not tied into one particular brand and we are entirely motivated by self-interest; we aren't compensated for the labour to replace parts under warranty. When we fit components we don't fit them for ease of replacement but for best performance and l ooks and then within the requirements of the standards.It is therefore in our interests as well as yours that we don't have to replace parts and so we make sure we fit the most reliable, long lived parts.
