I'm doing a Veg Oil Conversion and after much time and investigation have got it figured out and installed except for two nagging questions:

1. Went with a second FASS system under the other fender well to take care of the lift pump problem but am concerned that the heated oil (Shooting for 170 deg min) will work contrary to the design of the diesel actually helping cool the IP. Would some type of heat sink help?

2. The stock injectors aren't designed for Veg, a company named Elsbeth does make them, but not for a Cummins. I like their design thou
http://www.elsbett.com/pdf/injection.pdf Question is ,has anyone designed an injector for Veg or are any of the rebuilder willing to try it?

u will grenade the ip with those high temps., why not just run 50% oil 50% diesel so u dont have to thin the oil with heat ? or 60-40

I work with a Veg Oil Co and get it free, going to run Biodiesel in the diesel tank and straight soy,corn,cotton or rice bran in the Veg tank.

u will coke the injectors , pistons, head......i dont think this is a good idea on this particuler engine to run svo i think a 12v is better suited to this. IMO u can just do a 60-40 blend of oil to diesel or oil-bio...no need to heat the oil to thin it out. the bio especially, will keep things clean.

If you get veg oil free, the biggest problem in making bio diesel is taken care of for you. It is a hassle getting oil.

I run B100 in my '01 and I make it in my back yard. I would rather run Bio than SVO.

What year truck? If it is a P pump it will work fine. The Vp is not going to work with that temp. 98.5 and newer are the Vp44 And98.5 and lower are P pumped. You could convert a vp to p pump but thats a whole other ball of wax.

It is a 2001,VP44 and I'm determined to make it work, I've got bookoo bucks in this project already. What I'm after is ideas how to make it work. I know all about the history of this IP, how about the "Fed Ex" modification? One must keep in mind with a $300 a month diesel bill, the payback will be rather quick. The other idea I'm working on is heat tape after the IP that I picked up from fattywagon.com. If this works well, I may be able to lower the temp to the IP. I'm trying to stay between 70 and 80 on this chart:

Got no idea on the injectors, but do have the HO, 6 speed which I read may be more restrctive than the non-HO injectors

check out this web site: http://www.dieselsecret.com/ Their system requires no conversions to your turck at all. It may be worth looking into.

I bought a kit for my dodge but I think I will put it on my landcruiser(it has a clunky old idi 4banger 3b) so I think it'll love it plus if I wreck it messing around with oil/blends etc then it'll be way cheaper to fix. I think I will run b100 in mine when I get producing.

On injectors doesn't veg need larger holes ie less on the injector nozzle..... 370 marines would work??

Good luck with the vp conversion! Your a braver man than I ... let us know how it goes! Have you talked to plantdrive? Their guy in the cali branch runs a 2nd gen on wvo and it loves it.

By the way what site do you use for bio info?

96 ram, I've been working on this for a year and must have visited them all. The kit I got was from greasecar.com

For injectors check out; http://www.coloradobiodiesel.com/
They don't list them for this truck on their web page but I asked about them and was told they have injectors for the 12 valvers.
I don't feel you need to change out the injectors, the stock ones work just fine.

How well does the Bio and this veggy fuel work for you guy's up where it really gets cold? Any gel problems?Mpg diff?What major modifications If any?
Did you change filters more when first starting the change?
Just wandered have heard some complaints and thought i would ask the experts. :rolleyes:

Ken, I was hoping you would chime in here, everyone seems so negative on this project. Do you mind if I PM you, I have lots of ?'s

New to this forum and was asked to come aboard. I converted my truck back in Nov 05 and since then have 14,000+ miles on with no problems. I researched for quite along time before making the jump and feel confident it will work. IMO is the VP-44 will work as long as you have good pressure feeding the IP. At temps with the Frybrid conversion I should not experience engine coking as long as the oil is hot and filtered properly. The Frybrid controller will not switch over to VO until 170 degrees and have tested this regularily. I have not broke down the engine to compare but in a few thousand miles (292,000 to be exact) it will get the once over for its 300,000 mile check up and adjustments. I do plan on pulling the injectors to see if there is any wear or damage. This truck does get it's work out as I pull construction trailers while building cell towers. It does get it's share of highway mileage which is one on the main reasons I did the conversion.

There are others on the VO forums that have converted with the same success. Couple of things to consider. Most of the VP-44 issues have been with the upper control module and the FedEx truck syndrome. Most occured because of the constant starting and shutting off of the engine while making deliveries. The other problem we all Know and love is the crappy lift pump. One of the things I did was add the Walbro 6065 to the VO side and run inline with the stock LP which in turn boost the fuel pressure and extra 5 psi across the board. I now average on VO 20 psi at idle, 15 psi cruising at 65 mph and 8-10 at WOT. I did loose about 10 hp on the VO side, but who cares, as I am averaging around 300 hp now and noticed no real difference. Mileage has still been the same 20-22 at 65 mph. The other most need items, again IMO, is a fuel pressure gage and low pressure warning alarms. As long as you have good hot oil and solid pressure and no air, these things will run on VO pretty good. Besides, I took a $950.00/mo fuel bill down to $115.00/month so it will pay for itself in the next few months.

I have been satisified so far and glad I made the jump. Of course I had to prove the naysayers wrong, so did it for that as well. And I work through out IL, WI and MI so cold has not been an issue as long as I purge when I shut down at night.
Q

pqevill, think we met on another, perhaps somewhat less hostile forum. I am proceding, have the FedEx VP44 on order, am working with Colorado Biodiesel on a set of Veg Injectors, and have ordered Fattywagon's injector line heaters. The rest is pretty much done, except for some insulating, Greasecar, FASS, Vegitherm. Oh yea, fuel pressure guage and an extra thermocouple mounted right before the injectors. You're right, the payback is there and lets face it, it's the right thing to do. We've just got to reduce our oil imports.

Let me know how it goes with the new injectors. When I hit 300,000 that may be a good time to replace them. I have looked into Fattywagons design and that may not be a bad idea after the IP especially in this cold weather.

I'm also going to switch over this spring to the Vulcan bigline kit and get rid of the banjos. I am convinced that could also be the troubles. BTW, this is my one and only VP-44 so must have gotten lucky and only 2 LP's. Now if I only didn't jinx myself. You have my email address.
Q

Pquevil:

Can you give me some details on your conversion. I did a Plantdrive with the Horfox, Vormax and Mega Vegtherm on my '99. I am running a Fass for the Vege side on mine and an upgraded pump on the Diesel side that was with it when I purchased it. I need to get a pressure guage and was wondering what you might suggest. Also do you have a suggestion on Fuel temp guages?

I am also interested in one of the big line kits. The only problem I have had in 1000 miles is I seem to have sucked air into the system twice. The first time was due to some loose connections. The second(today), well the jury is still out on that but I think I may have run my tank a little low. It's raining so I haven't been able to test my connections again yet. :rolleyes:

What I really want to know is why people think that the VP can't handle temps of 160 degrees or above. You guys don't think that thing is seeing consistently higher temps when it is mounted right on the engine? I betting it regularly sees over 190. Suer the fuel may cool it but what about in the summer on a low tank? That fuel would be warmed by going through the IP and back to the tank the whole time you are running. Mybe I'm nuts but I think that those temps are way less of a problem than the naysayers are thinking. Any input?

Mine is the Frybrid conversion. Heat has been fine and have the FPHE before the IP and only a sensor to trigger switch over. I went with a boost gauge inline at the IP entrance so in order to measure both pressure and vacuum. I have the Walbro 6065 inline on the VO side only which meant rerouting the diesel so that after the 3 port valve it pulls diesel through the stock Fuel filter. I gained an extra 5psi accross the board becuase of the extra vane in the stock LP. I did it in that fashion thinking that I would have a back up and didn't have to shut off the stock LP. But with the reliability of the stock LP, have been re-thinking and possibly installing a FASS and big line kit for VO side and just switch off the stock LP via a relay on the Gen-3 microprocessor. Another idea was to use the FASS for both and then have a bypass to the stock LP in case it failed I could switch over to the stock LP on diesel to get home with. A lot of ideas and still too cold up here to start and will wait for the spring.

There has also been some interest in Fattywagons injector heaters and good test results that even Dana Linscott has been testing them. It would make sense for the Cummins so that you would have 200 degree heat going to the injectors on the VO side. I'm up to over 15K in mileage on VO so working good so far. Good to see Graig eased up on the 24v's, hopefully my results had some influence.
