APS lpg system failure

[simonr23]

my au's aftermarket system died last night. i dont know much about lpg systems, but from a bit of googling and general knowledge, i think a solenoid in the engine bay is the part that's fried itself.

car died at the lights (while on gas)and smoke came from under the bonnet, with a burnt electrical smell. i looked under the bonnet and this little device with a few wires was popped and blackened, it's near a larger device(regulator maybe?) up near the brake fluid resorvoir.

my car is an au1 fairlane 6cyl, and the gas system was fitted back in 2001.

am i right in what i think has failed? likely cost of replacement part(s)
car is fine on petrol still.

thanks.
