Default Does sytem backfill if you click/turnoff while engine still running

Does sytem backfill if you click/turnoff while engine still running.

In previous posts i was informed that its normal for VO/D2 mix to return to tank while green or possibly if not...if I then turn/click my sytem switch to off will it backfill while im still running or will I still need to turn back on and auto backfill once I turn engine off?

Vergie - If you allow the system to shut down automatically by just turning the key off, it will purge veg from the engine and the V3 and then continue to run for 90 seconds or whatever you have it set at. This will cause the veg left in the heads/injectors to be burned up and be replaced with diesel. If you interrupt that sequence by turning the V3 switch off after you turn the ignition switch off, the engine will stop and you will end up with veg remaining in the engine and/or the V3 (not good). - Patrick

It will not purge. All it will do is use what's in the fuel rails while it's still running. If the switch is off, as soon as you turn the truck off, whatever is in your lines and leftover in the rails will stay there. In short, don't let it happen.

What Drew said. If you manually turn it off, you need to manually hold the purge button for 8 seconds or so. Then it will "backfill" AKA "Purge".

Default Ok, but...

I get that. Im talking when your green, truck running, you turn system off manualy (green now off), truck running. The sytem doesnt back fill at that time either. That switch disingages the veggie system! No need to reply unless I misstated.

Thanks

Vergie - Not exactly sure what you are asking. Does my post (Lancaster, PA) above help any? If you are driving along with a green and you turn the veg system off with the rocker switch, the system will not purge diesel through the V3. If you drive long enough, you will eventually (long time) burn all the veg out of the engine, but if you stop and shut the engine off with the key, you will still have veg in the V3. - Patrick
