secondary pump plumbing question

plumbing in a second pump for wvo.

Do you use the dead head design with a single line feeding both heads?
No return? My pump is internally regulated.

What check valves do you use?
Are they reliable? Don't want to be pushing wvo into the d2 side.

Any links or pics would be helpful.

Thanks


Truck is a 2000 F350 7.3.
Two tank system. Wvo tank heated.

I have CV's for the D2 lines from Leon. They are 25 bucks a piece & are stainless. He has them for sale onb his website. I have 32k miles on them & they are working great.

Keep the fuels completely seperate right to the heads. Use the plugged ports in the heads. That's where you will put your VO fuel lines. Go to BFT's site & download the instruction manual for the 7.3. Shows you exactly how to do this. I would provide a link for you but I don't go on that site anymore.

Mine is deadheaded. There has been quite the on going debate if a regulated return is required. Mine has run fine deadheaded.

mine is deadeaded. works great!

im not sure you can use the stock mechanical pump in this fashion. i could be wrong...?

i used two cv's i found on mcmaster. they worked great untilt eh truck was totaled. it was only labeled to work up to 190*F, but the little plastic piece in them has a melting point of over 300*F i think. so ill probably use those again.

as i said, i was deadheaded, i think stock power levels and even a little more its fine, the vo sits longer in the heated areas of the engine, fphe, hih, or rails. with a regulated return you need to be sure your getting good heat to the fuel as it passes through much faster.

His truck is a 2000 so it has an electric pump.

Your truck is totaled? What happen?

I have a dead headed regulated return

For all my short trips around town I run dead headed, once I hit the open road for the long haul trips I flip on my solenoid and run regulated return.

I do this so that I don't cook my vo pump with to much heat.



I run two fuel lines up to the engine bay, then use CVs and run the fuel through a fphe and then into the back of the heads. After the heads I have a regulator and solenoid valve with return lines to both wvo and D2 tanks. My D2 rerun has a ball valve (always closed) and the solenoid energizes my return flow for wvo purging/wvo regulated return.

I use stainless 1/2" npt check valves off feebay, I can dig up the link again if you really need it
