What do you DO when WVO is left in the system by accident

Had it happen two weeks ago with a carpool buddy. Ended up draining the fuel line to injectors, priming it with deisel for fuel pump and still killed the battery trying to start it. Made a nice mess of engine and school parking lot too!
Engine was very sluggish for first ten min after as well.
Maybe the reason for going to WVO controller?????
Any other similar stories with your solutions?????

i remove the line at the IP and use a suction pump to pull out the WVO untill diesel start to come. then i just crank until diesel is in again and it fires

After doing as Afteroil stated, remove the return line from the IP, placing the hose end in an old bottle of some kind, and crank till diesel flows through the return hose. Maybe three 10 second cranks should do it. Caution though, sometimes the engine can start while flushing the return line.
If you don't have a WVO buzzer; do you have a sign, front and center on the dash? 'Don't forget to Flush'

OR: take a propane torch and heat all of the injection lines for several minutes!
the small print: i have done this, and someone i know used this technique all summer long (didn't burn any diesel in the summer), so i know that it works. it will undoubtedly put extra strain on the injection pump. you obviously do have to be careful of all plastic and rubber bit close by. maybe not a technique for the faint of heart but i roll like that!

Hey Shayne,
How's your centrifuge running??? You've gotta post a video of the process on YouTube and link it up. I'm thinking I might be able to sneak some of the centrifuge components onto the materials list for the house we are building and my wife would be none the wiser

. Anyway +1 for me on the buzzer, which is a bit hypocritical because I haven't wired mine up yet and have the dead batteries to prove it.
Injection line heaters are a cheap solution that I'm toying with, I just haven't gotten around to ordering them yet.

Our 30" 100 watt heater will work on most 4 thru 6 cylinder cars with displacements of up to 3.5 liters (3500cc). For V-8 (Ford / GM) and larger inline 6 cylinder engines (Cummins) use 2 100 watt heaters. Price is for each heater is $40.00. Shipping included in the Continental USA. Canada add $5. Anywhere else add $10

Didn't want to admit to doing this also; but one early morning below zero, in a hurry to catch a ferry and hung over from the staff party the night before (plus starting up on WVO in front of the hotel with co-workers from the entire island watching) used a small soldering torch to heat the lines and injector tips.
Warning; didn't feel this was the safest way to go.

I wish I'd thought of and/or had the balls to try a propane torch. It takes forever with an electric heat gun and it looks like you are using a hair dryer on your engine, looks very desperate.

Thanks guys,
I did find a drain bolt on the injector pump, which drains by gravity alone...I found this out as well! I may try and get a suction pump attached to a 1/4 barb with the same bolt size to attach and suck diesel right into the pump. Will keep you updated.
I thought this would make me laugh. I do keep a blow torch in my van!
Adam, I like your injector heater Idea. I will look into it more.
Re the Centrifuge...maybe get to it in Jan. Just too busy playing or working. It's working real sweet now though.

Ok, guys trust me on this one.... here is a safer method than a torch:
-if you don't have a buzzer, and you don't have an engine heater (block heater or oil pan heater), and you leave it on WVO, all you have to do is get a big pail or hot water from the bathtub and pour it slowly over the injectors, lines, and injection pump, wait about 30 seconds, hit the glow plugs, and fire it up (on diesel, of course)
- then get a buzzer. We send them out with our 6-port valves, and with our kits, but if anyone really needs one, contact me via an email (preferred over a PM)

ok I haven't actually done my conversion but once I have I wont do anything but start it again, and I will never pruge it

. How you say? The joys of a single tank system. ok I will sort of purge if it get below -10 by going to a 50/50 mix and then at -15 or -20 I'll go to dino but in Victoria that is very rare, I might just install some of the line heaters for the injectors and injector lines just in case but I will wait till next fall. will be cool if I ever get to install the 2 extra tanks I want to install so I can have 3 tanks of WVO, I'm also very tempted to add a centrifuge to one of the extra tanks for mobile filtering/dewatering ah dreams are great aren't they?
