Supply Pump for 12V

hey Guys
Building a 2 tank veggy system to run WVO in my 96 12 valve. I'll have a HIH fuel line, heated fuel filter & a hot stick pickup etc. What are you guys using as a supply pump for this?

try this pump:
Electric Fuel Lift Pump [1130500] - $289.99 : Pacific Performance Engineering, Innovations in Diesel Performance

Or this one
PureFlow Airdog Universal Raptor Pump

Or this one which I intitally tried. Was told it was bullet proof and lasted me only a couple of weeks but then again I have terrible luck so to be expected.
Walbro FRB-5 Industrial Fuel Pump from Fuel-Pumps.net

The first two are rotary vane pumps and the last one is a piston pump. rotary vanes will be less likely to bog down if the fuel jells up but have the potential to cause dissolved air.

thanx Dieselluver.
The PPE & Walbro do not have the pressure needed by the P7100 pump at 17 psi min. pressure. From what I understand, these P7100 pumps like presures around 30psi.
I don't know if anyone modifies a Air Dog or FASS for use with WVO- ie: Viton seals, but they sure are expensive & I 've read there's reliability issues with them.
i'm hoping to find a WVO compatable pump that can be purchased for less than the Air Dog or FASS @ $400.00
I have most of the conversion stuff now for my truck including a 60 gallon alluminum tank, hot stick, heated filter, & heaters for the injection lines. just need a pump,HIH, & solenoids now.
I've been running my cold upflow settling system now for over a month & it's working out real well yielding me about 90 gallons of clean, dewatered WVO a week.

FASS uses viton o-rings and seals in all of our systems.

I suggest using part number FA D11 090G for your application.

Oops, I'm bad. The Raptor pump I gave you a link for is specifically designed for WVO. It's rated at 35 psi. Plus I don't see why WVO would need special seals anyways as it's not corrosive and has no solvency at all unlike diesel, biodiesel and gasolene. I use a 3gpm 12v fresh water pump made by Sureflow to transfer WVO from tank to tank and I think it has just a plain ol rubber diaphram. In fact I was gonna use it on my truck as a WVO fuel pump but I have a 1st gen and anything over 15psi with them is supposed to be too much.

Screwed up again. There are two versions of the Raptor that will work. One is a 100gph 55psi (max) pump and the other is a 150gph 30psi (max) pump.

here's another link to this pump for WVO use:

I installed a raptor 100 in my 94 fuel system. I am running a split fuel system in mine. It works ok but I would probably use a oem mechanical fuel pump if I did it again. Are you going to use a separate pump for your auxillery tank or will you use same pump for both fuels?

Where i had problems was that I used the same pump for both fuels. The fuel from the veggie had to travel a way before it got to the pump. This was the issue with the raptor, it likes a lot of fuel fast with no restrictions on input. I was pulling the fuel through a filter and then into the raptor. Not good.

I am planning on using the same pump for both fuels, with a solenoid valve mounted on the Inlet. N.O. for diesel, & 12 Volt powered for veggy. I'll mount the pump & solenoid very close to the fuel supplies, (on the frame near the front of the box) Me thinks this would be a simple way of fuel supply. I am open to all ideas & suggestions tho

supply pump

I'd highly recommend having a totally separate fuel system. If one starts to fail for some reason whether it be filter clogging or fuel pump failure or air contamination it simply takes a flip of a switch to continue on your way (don't ask me how I know...) Also I'd highly recommend having your solenoid switch as close to the inlet on the injection pump as possible to minimize switching over for two reasons. One is it will minimize temperature loss if your running heated WVO and the main reason is if you do have a air contamination it will not take 10 minutes to swich back to the other fuel. Also you should have a separate switch on the return lines to purge any air out of the system.

Just my 2 cents worth.

Like I said, always open for suggestions. Sometimes it's better to listen to someones mistakes, & build on them.
So, 2, complete separate fuel systems. The diesel side would be untouched original, xept for the 3 port solenoid right at the injection pump inlet, & another 3 port for the return fuel .
Question tho, while running on veggy, the stock mechanical lift pump will be dead headed with no fuel flow. that can't be good for it.
