Before you start, make sure you have:
- Soapy water
To check the refuelling hose:
- Visually check the refuelling hose for damage, such as fraying and cuts.
- Apply soapy water to all valves and connections.
If bubbles form, there is a leak in that assembly or fitting. The fitting may require
tightening or the seals might need to be replaced.
DANGER: You must isolate the gas supply and depressurise the dispenser before
disassembling any component or adjusting any fitting. Serious injury may result if
components are removed while the dispenser is under pressure.
Replace the hose if it is damaged or leaking.
Before you start, make sure you have:
- Soapy water
To check the operation of the isolation ball valve:

- Open the bleed valve on the utility manifold block (where fitted) and bleed the gas
from the refuelling hose.
- Close the bleed valve once the hose is degassed.
- Start a fill.
If the pressure gauge starts to move, the isolation ball valve is leaking or passing
gas.
- Apply soapy water to the valve.
If bubbles form, there is a leak in the assembly or fitting. The fitting may require
tightening, or the seals might need to be replaced.
