JHM Do you mean fuel cutoff valve for carburetted LPG? I recommend injected LPG as much more reliable. But you can use carburetted if you want to. You don't need fuel cutoff valve as you can cut fuel by feeding 12v to the EXT input
VulpesIgnis I mean, how do I send LPG to the fuel rail for injected LPG? Just use a gas solenoid with a check valve or do I need to use a switchover valve?
