Dunno if this will help, but... I've got LPG and the sub tank light flashes when I'm running LPG, i.e. with the sub tank switched off. I asked around here, and apparently it's just letting me know that the main tank is missing.

Usually the light will flash when there is a fault in the system, I would suspect possibly either fuel level sender (do the gauges still work??), or they probably also have level switches in the tank, which can fail.

In the GU patrols you can sometimes just disconect the battery for a minute and it comes good, they can get 'confused'. so that may be worth a try.

Hey Steve ,
Chris here Wil N's Navi thanks for that, yep the gauges still work every thing seems to be working ok have tried disconecting the battery and it's still the same, might have to check the sender units and level units just got to find them, got a manual so I'll give it a go, if I get stuck I'll give you a call and might have to bring it up to you to sort out.
cheers chris
