LP Gas Pressure Regulator/Vaporiser
During the course of normal operation oil or “heavy ends” may build up inside the
secondary chamber of the LPG pressure regulator/vaporiser. The oil and heavy ends
may be a result of poor fuel quality, contamination of the fuel, or regional variation of
the fuel make up. A significant build-up of oil can affect the performance of the pressure
regulator/vaporiser.
The oil should be drained from the LPG pressure regulator/vaporiser periodically in
accordance with the maintenance schedule. More frequent draining of the LPG
pressure regulator/vaporiser is recommended if substandard fuel is used.

Toyota Engine LP Gas Pressure Regulator Oil Build-Up
The Toyota LP gas pressure regulator/vaporiser is mounted under the bonnet to the
left hand side of the engine.
Draining Oil Build-up from the Toyota Engine LP Gas Pressure Regulator:
1. Park the truck in a well ventilated area and ensure no external ignition sources
are present.
2. Lower the mast fully and tilt the mast fully forward.
3. Start the engine and wait until it has reached its stable operating temperature.
This will help the oil to flow from the regulator.
4. When the engine is warm, close the valve on the LPG bottle fully.The engine
will continue to run until it has used up all the fuel in the fuel lines.
5. When the engine stops, turn the ignition key switch to the ‘0’ (off) position and
remove the key.
6. Isolate the battery by turning the battery isolator key switch anticlockwise.
7. Open the bonnet from the right hand
side of the truck to gain access to the
LPG pressure regulator (
A
).
8. Ensure all parts concerned are cool
enough to touch, otherwise wear heat
resistant gloves before proceeding.
9. Unbolt the regulator bracket (
B
) by
removing the two bolts (
C
).
10. Turn the regulator and bracket assembly
clockwise 90° about the x-axis.
11. Open the drain plug (
E
) which should be
at the bottom of the regulator after
performing the previous step.
