Tapping into fuel system

[dpantazis]

I was talkikng to a friend who went to one of those 'commecial' WVO conversion places and had a full conversion done to his X. $$$$

He tells me that 6 port solenoid is between main and WVO and the OEM fuel pump.

WVO side return line is looped to the fuel supply side.

the whichever fuel he is running, flows through the factory lines to the OEM filter.

that was pretty much it.

so on switchover, the volume of WVO from filter back will go into the diesel tank.

seems pretty simple.

any comparisons or critiques?

That's essentially the conventional system used by most places. A few have separate filters, but to my knowledge the Vegistroke setup is the only one that completely separates the fuel systems. Even then if you use Jasons fast purge there will be some fuel mixing in the tank.

Ideally, the conventional systems should be using some sort of air removal device and eliminating the return to tank. I am experimenting with this on a 6.2 diesel, tho not very far along on it yet.

I went through a couple of stock fuel pumps with this system. The Ford frame mounted electric fuel pump on the 99-03 7.3 PSD's just isn't built to handle the thicker vegetable oil. This came from a tech at Carter Fuel pumps. Same goes for the replacement pumps.

I'm going to a Vegistroke style dual fuel pump system using a Mallory 110FI gear style fuel pump, built to handle the thicker fuel. The initial cost will be a bit more but it would have saved me in the long run from replacing fuel pumps after 12,000 miles or so.

todd-
what are you planning for regulator? filter?

I have basically the same set up as your freind except my veg doesn't go back to my tank. I just have it circulate and mixes with diesel until is is all gone. Super long purge time though of about 10 minutes for complete purge. I would never recommend that as half the time I only drive 10-30 minutes. That is what my MB is for I guess. Heck I don't even worry about converting the car. I just pour it straight in the tank when it is half empty some times.....loves it

BTW Dennis, how many miles do you drive on an average trip?

If you're not doing alot of long runs or doing over a half hour commute, then you might want to consider making Biodiesel instead. You can run it full time, no conversion needed. You would need to dilute it in below 50 temps, but a processor can be built in the $200-500 range, giving you approx 80 cent a gallon fuel.

EXCATLY!

BTW Dennis, how many miles do you drive on an average trip?

I had tried asking this EXACT question before with no responses. There has to be a point where the return on investment for WVO vs BioD has to be met for it to be worth anything.

In my case, the commute is roughly 30 miles each way. time- it could be as short as 45 minutes or as long as 2 hours- Chicago traffic. So from what I have been reading, I should be be good running WVO.

My weekend playgrounds are all at least 60 miles away on weekends.

Lastly, The WVO storage will be near domestic animals and would be where I would brew BioD. I am not too keen with them sharing the same space with methanol. So I am working towards WVO.

Makes sense. Usually you'll be on WVO within 6-8 miles in the morning. You can also plug in the block heater and get on WVO sooner too. Depending on the system you use you'll either shut off WVO 2-6 miles before stopping, or with fast purge approx 15 seconds.

Some fuel for thought

I started making my own Bio-Diesel in my garage and to tell you the truth it was the easiest thing I have very done. Some of the systems you have to have 2 college degrees to figure out the mixing combonations. This system is 5 different things mixed together. An elementary kid could do this system. I started out using vegetable oil from resturants, but got a couple of bad oil batches now I am going to buy the veg oil at 100 gallons at a time. With total cost of everything it comes out to be about $1.40 per gallon that price is at 100 gallons. No conversion needed, if you run out you can use regular diesel with no worries. Makes me hungry driving though smells like french fries.





I feel bad about the title............................ Ew, I'm over it

whats this fast purge consist of? I am looking into runnign WVO. going to start gathering parts to do the conversion.
