specs on fuel supply to the heads...
<hr style="color: rgb(209, 209, 225);" size="1"> <!-- / icon and title --> <!-- message --> <table border="0" width="100%"> <tbody><tr> <td valign="top"> I'm going for my WVO conversion.


I'm creating a complete second fuel system using a hydraulic pump for the WVO.


Now, I need to "Tee" into the existing fuel supply to the heads, what thread and size are they?

Also, I want to install a drain valve on each head, (where the fuel return was on buses etc), what size is that plug???

Thanks in advance.

Not meaning to offend you, but:
Judging by your post I would say you haven't studied the WVO conversion idea very much. I guess you could "Tee" into the lines, "Drain" the return and such but there are better ways to do this. Check out how the VegiStroke is plumbed od look at the Frybrid information and you will have a much better idea on how to do this.

How are you going to regulate the fuel pressure?

 

Sorry, i didnt elaborate any there,

Where the line goes from the factory fuel bowl to the head, I'm putting a chack valve and also a check valve on where the WVO line T's into the normal line.

This way, if my WVO setup dies, truck rolls on without a glitchh.

I will run the WVO regulator slightly above the dino diesel regulator, as to close the check valves on the diesel lines and run on WVO provided pressure is adequate.

I want the drains on the heads to do an "emergency purge" if necessary.

The WVO will be regulated by a large adjustable fuel regulator i got for 20$. Already tried it, seems like it will work.

I actually already had a truck at one time running off WVO.
