Our 1998 GU patrol Y61 is running on petrol (sub) and LPG (main tank), however its running fine on the sub, but does not on the main-gas tank. We've looked quite thoroughly and can't seem to diagnose anything broken, apart from that it could be the solenoid that's causing issues.

Problem now is, where to find a solenoid to replace and fix it so we can actually use our patrol properly. Does anyone have any idea, suggestions, advice on what solenoid to get - TB45 - whether there's any compatible aftermarket ones, and or where to find one?!

Thanks heaps
