Hi,
is there a way of testing new fill hose connections before actual Forecourt attempt. I vaguely remember a thread on the subject. I have a separate cylinder but not sure of bits needed to connect it to filler (euro flat fill Autogas 2000)
Any thoughts?

The pre fill test needs a connector hose and you pressurise using air. most diy installs though just test using a couple of litres of lpg and leak test spray or even washing up liquid and water. put a few litres in and spray the joints, any leaks will blow bubbles. if as is usual, the install is ok, continue to fill the system and note how many litres are taken. if this exceeds 80% of the cylinders capacity, then the float is sticking. do not try putting more gas in at this time. the fluid lpg slopping around in the cylinder as you drive nearly always frees of the stuck float valve. subsequently after using the filled lpg, when you fill again the 80% shut off should now work

Thanks, but what connection can I use from external cylinder to the filler point to introduce the LPG into the system

Why use an external cylinder? Gaslow sell a converter pipe that connects an external cylinder to the fill point. costs about £25

thanks, so that fills system to cylinder pressure (gas phase). It should show up any leaks hopefully.
