Two Birds - Veggie Conversion Thread

Hello Everyone,

I have had several requests for info about our veggie conversion. I will open up a thread for our veggie oil conversion in the WVO Section. It's an ongoing journey that we just started For our bus conversion, visit here:
viewtopic.php?f=9&t=467346

Just last week, we received many of our conversion parts for our 1992 Bluebird School bus. It is a 5.9 Cummins and has a P7100 Bosch Injection Pump.

After a lot of research, we decided to go with mostly WVO Designs parts and their centrifuge for an on-board filtering setup. After some chatting with Leon, the owner, they decided to sponsor our project, which is really exciting for us. This is a first conversion for me and I have been spending many, many late nights researching the system and figuring how to adapt SunWizard's setup for our bus. He is the owner of the forum www.burnveg.com. I am sure we will have lots of questions as we go. This week, I will be rounding up parts such as fittings, fuel line, coolant hose, etc.

Here is the diagram from SunWizard for his 5.9 Cummins that we will be basing our system off of:


Here's our conversion parts list so far:

Tank:
116 Gallon Aluminum Military Fuel Tank.


Fuel Pickup:
http://www.wvodesigns.com/shop/wvo-conv ... tickb.html
WVO Designs RAW Power Hotstick
13" - Will be expanded via the threaded port to ~26" to pick up fuel from the bottom of the tank.

Veggie Filter:
http://www.wvodesigns.com/shop/wvo-conv ... ilter.html
WVO Designs Coolant Heated Filter Head
Donaldson P551000 Filter/Waterblock with Drain Bowl
WVO Designs Heated Filter Wrap

Flat Plate Heat Exchanger
http://www.wvodesigns.com/shop/wvo-conversion/fphe.html
30 Plate from WVO Designs

Valves
http://www.iboats.com/1_4_X_1_4_X_1_4_N ... w_id.67211
iboats.com manual 3 way valves, per SunWizard's conversion - X3

We also got the following to help us collect and filter oil:
Centifuge
WVO Designs Raw Power Basic Centrifuge
http://www.wvodesigns.com/shop/centrifu ... ifuge.html

Bolt-On Heater Assembly
http://www.wvodesigns.com/shop/centrifu ... r-rpc.html

"Power Booster" - This helps to eliminate splashing as the WVO enters the centrifuge.
http://www.wvodesigns.com/shop/centrifu ... oster.html

Transfer Pump - We are mating the WVO Designs pump head to a 5.0 HP Honda Gas Engine we recieved for free from a pressure washer that had a broken pump.

Goldstream Monster Pump Head

Re: Two Birds - Veggie Conversion Thread

Be careful of the info you read on the net about p pumped 5.9 cummins. Most of it will be about dodge trucks, not buses.

What was SunWizard's conversion? The reason I ask is your diagram shows a lift pump. Your bus has no lift pump in the fuel tank. For easy priming, you will need to install a inline electric pump.

He speaks about his mechanical lift pump that is driven by the engine piston. Isn't this exactly what our bus has? When I get back to the computer, I'll get you a link to his full conversion. I won't be copying it exactly, but everything I read says we have the strongest and most reliable lift pump out there and not to add an electric pump because they will go bad over time. I'm not opposed to it if it is necessary, but this diagram doesn't imply a lift pump in the tank...

The full diagram doesn't show up for some reason. Right click and click "open image in new tab". That might clear up some things!

Re: Two Birds - Veggie Conversion Thread

Yes our buses have the mechanical lift pump on the side of the engine. Yes that is the best for running diesel, and never running out of fuel, or changing tanks.

Most WVO WMO Bio users run a electric before the mechanical lift pump to prime the system. Otherwise you will hate yourself pushing that black button on the lift pump on the side of the block a few hundred times.

Re: Two Birds - Veggie Conversion Thread

Another option might be to put a fitting on the fuel tank that allows you to pressurize it with compressed air. When I change fuel filters on my WVO car, I blow air into the tank, forcing the fuel to prime the system. Of course the system has to be opened somewhere so the pressurized fuel can flow. I'm sure you can design an easy to use fitting with a machine screw and o-ring somewhere just before the injection pump to create that outlet. That will reduce the amount of time you spend cranking the engine to get it primed. The biggest problem I've had with bio fuel systems is finding tubing that will not degrade from the fuel. Viton, of course, is the thing for any kind of gasket. And there is special tubing too that is designed for the purpose. Next time I install a WVO system (which I plan to do in my bus) I will use all banjo connectors. Hose clamps are not your friend, trust me.

I have been considering this for the portions of the bus where the fuel is not under high pressure. Thoughts?

Also, could you let me know more about these banjo connectors you are talking about? I am not familiar with them.

Re: Two Birds - Veggie Conversion Thread

I've tried that hose from procycle. It failed. I can't believe they are still marketing it for that purpose. Maybe nobody ever told them it doesn't last. I've tried every kind of translucent tubing you can imagine. It all failed. I love the idea of it because you can see where air is getting in. But it does not last. You want to find hose made of Viton or similar material marketed specifically for biodiesel. In my research I found that SAE 30R9 fuel injection hose was the best alternative to Viton, and less expensive: http://www.goodyearep.com/ProductsDetail.aspx?id=5144. I also found this stuff: http://utahbiodieselsupply.com/biodieselfuelhose.php. It's been a while since I looked into available products, but it seems like the market has responded to this demand. It seems like a key word is " Fluoroelastomer". It will be more expensive that regular tubing. It will be worth the money. Seriously. The majority of problems I've had with my WVO system were related to hose failure. The translucent hose gets brittle and splits, and the typical rubber hose just turns into slimy gook. Just do it right the first time and save yourself a lot of grief and roadside breakdowns.

Banjo fittings look like this: http://www.demon-tweeks.co.uk/motorspor ... fuel-banjo

You take your fuel hose (already cut to length) and banjo fittings to a fuel injection shop or hydraulic supply house, and they have a machine that clamps the hoses onto the fittings with a special sleeve. I have not yet tried this method myself, but this is how diesels are set up from the factory in parts of the fuel system where steel tubing is not used. Check out your bus engine, and I'll bet you find some of these fittings. The problem with hose clamps is they cut into the tubing, and any time you loosen and re-tighten them because you had to remove a hose or whatever, they become more and more damaged. Then the WVO starts eating at the end of the tube - even the good tubing is often only lined on the inside with the Viton, but the outside is susceptible to degradation. Typically, hose clamps don't even really seal perfectly. The banjo fittings use soft metal (copper or aluminum) crush washers to seal them, which are easily replaced. The tubing never gets messed up because it isn't being squished and torn up by the hose clamp.

Re: Two Birds - Veggie Conversion Thread

I'd avoid banjos. Besides being costly, they make a gret place to start a restriction. Let me share a learning experence:
From the 1st time you make your own oil-and the 1st mile you drive, you'll always be learning. And some of those lessons will be the hard way.
No matter how clean you think you got your oil, there will always be some "paprika" in it. (Fine brown powder build up.) If you don't get your oil clean, the stuff will plug filters-and build up in your system. If your oil is clean, it will just take longer to acumilate.
I had a lesson about long term maintance on my Jetta-after 120k miles on veg. I had a fresh rebuilt engine-and hopped up pump. I had my thottle go wide open on me. I chased it down to a big pile of paprika getting in the pump + holding the fuel pin. But where did it come from? The pump was only on the car about 3k miles. I started by undoing hoses + blowing air thru the system-all kinds of crap came out! I tore into ever inch of my system. Magnifying glass + pipe cleaners. I was shocked-every elbow had a little -and the banjo going into the pump had a bunch. Same with my solenoids. Everywhere you had a change of direction,there was schmutz. Just a little bit--over a long time.
Here is good choice for hoses. Push lock connectors + hose. http://www.mcmaster.com/#push-lock-hose/=ryew1i Only $1.50 a foot-and comes in colors. No hose clamps-no leaks-no getting things crimpped.
Heres my system-mounted underneath the bus on a slide out track.

That's a pretty slick setup! Do you have a WVO Thread?
