my diy wvo conversion

[mpiller]

Well I've started on my diy conversion and I thought I should make a post for it just for some advice and a few questionsor to help anyone else trying to do the same thing. First off it is going on a 2000 f250 with the 7.3. I custom built a 65 gallon heated tank in that fits in the back of the bed. Both the filter and pump for wvo are mounted on the side of the tank. I have attached a diagram of my set up, the pic is not very good but it helps. Brown is vo, blue is coolant, yellow circles are gauges. The diagram is shown while driving on diesel, all of the sov's are de-energized. I will have one on/off switch for the pump and a 3 position switch for vo/neutral/purge. The vo position will all 3 sov's, neutral will de-energize all 3 (start up), and purge will de-energize just the diesel supply sov so to purge the system before shutdown. I'm using a recirculating system for the vo to help heat it. When I start up I will turn on the pump to start the recirc loop, and once it is hot enough I will switch the 3 pos switch to vo. ANy problems with this setup? Since I am fairly new to this truck my question now is where do I tie into the fuel line and where is the stock diesel return line? Thanks for all the help ad I'll be updating this thread with pictures along the way

This is a little better picture of the diagram. I'll take pics of the tank/filter/pump tomorrow.

im still trying to decipher your diagram, but first to note, international convieniently place two more fuel ports for us to run veg! so no need to tie into the stock fuel line. on your 2k psd they are opposite the stock feed lines in the head. front and back of the heads respectivly. tubular031 may have a pic of this in his setup. put a couple of cv's there and run the fuel in. also may want to put a couple of cv's on the diesel side same location, if the 2nd gen psd doesnt have them already, which i think it may.

what does sov mean? its early am in sure im just missing something.

the sov's are 3 way solenoid valves. Ive read about the otherfuel ports, but how would I run the return from those? To me it jst looks like it would be easier to tie into one stock fuel feed line instead of making two new ones? maybe its more complicated then that?
Thanks for the help

if you want a regulated return then thats good as well. in that fase i would tie in just before the heads with a 4-way and 2 check valves. thats how i would do it anyway. there are many methods. just dont let your veg mix into the D2 fuel bowl.

ok, could I not tie in right before the fuel bowl?

are you wanting to use the stock fuel filter? or no. if yes. dont. setup a separate veggie filter and its best not to contaminate your diesel system for potential issues that might arise.

Ah young gwrasshoppa...your learning well.

No, I am running a completely seperate system for the vo with a seperate filter and pump, but my question is will it be clean enough to run through the fuel bowl from there? or will i go through filters too quickly? If I tie the vo lines into the unused ports, how would I run the return lines? or would there even be a return line since the fuel is deadheaded?
Thanks for all the help

I see now. Its a dead head setup with them check valves. it should be clean enough after the cf run. And the fiter for the rest.


Then purge the engine before shutdown to burn the veggie out of the heads and be full of diesel.
