looking into the whole bio diesel thing and was wondering if running straight bio diesel would hurt a 2nd gen 12 or 24 valve?

John Faughn

There is more to this question , the 12v its OK , but the 24v have 2 or 3 different fuel systems , and emission systems , so that is where the ? needs to be looked at with each of systems .
On a time line , the 1st would be the high pressure common rail system is a problem , then the mutable injections , which is part of the emissions , then the particulate part of the exhaust .
So only the early 24v with the VP main pump , is OK with B100 .
You will be reading that there are some out there that say they have not had a problem , or there friend or relative .
Then main point here is that the newer the system the more likely the chance of issues , if your willing to bet a $50,000 truck , then its all on you .

IIRC for the 12V the only thing that may not like Bio is some of the older fuel lines were not compatible with Bio. I think the 12V will run on just about anything you put in the tank except dung.

In addition to bio-proofing the fuel lines (bioD is cleaner and much more corrosive than petroD), you will want to have a spare fuel filter in the truck once you start running the biodiesel...

The bioD will "clean" most of the carbon and petro-gunk that has built-up in the cylinders, injectors, etc. This will happen w/in the first 1-2 tanks of b100 that you run... and all that carbon and gunk will get trapped in the fuel filter. At some point in that first 1-2 b100 fill-ups, you'll be going uphill and the power will drop off... so you pull over, swap in a new fuel filter, and you be good to run on b100 for 300k+, imo.

I've been running b100 in my '05 for 12+ months... cost? $1.20/gal. + one fuel filter. problems? none.

thanks for the replies! good stuff to know..... what would you reccomend as far as fuel lines if they are a problem with b100. and the 24v i am refeering to would have the vp44 (98.5-02 i believe right?) i wish i could afford a new truck but on the other hand i'm happy with what i got just looking to save some money. also..... one more question.... are you making your bio? and if you are what systems are you using? and do you like them or would you have gone a different route?

ok so that was three more questions.....

John Faughn

The only thing , and that would be an extra , is a high quality water filter/ separator .
I've been buying , commercially processed for over 3 yrs , now I am building a homemade processor , about $300 to 500 , depending on your ability to scrounge , it has a name , Appleseed , there is a large do it your self community associated with it , heres a link to there forum .

The way I see it is if you can make stuff [ save money ] & have the time , build your own , if you making good money , but have less time , the Bio Pro is getting by far the best reviews for a automated / turn key processor .
But the cost is about $10,000 -12,000 .

What modifications must be made to a 2002 dodge 2500 ram with the ISB 5.9 L Cummins for it to run biodiesel either B20 or B100.

Hi,

None, just pump it in and use it. Vegetable oil use is where you need special conversions made. Thats a great truck, enjoy!

Hey Matt,

why does Cummins and Dodge only recommend B5 in that truck???

The main reason is to protect themselves from issues that could arise using higher concentration levels because some pre 2002 fuel systems have rubber components that are susceptible to damage using B20 and B100.

The only reason I said no modifications on yours is because I have read where others have been successfully using it with no trouble and there are no modifications that I know of to use it however based on Cummins recommendations I suppose there is some risk depending on specific components used on your 99. Going through the entire fuel system upgrading to components used on the 2002 seems wasteful when you might run it fine for several years and then have to replace a lift pump that failed from its use.

It does boil down to some risk though so you have to decide if its worth it.

joe189man,
thanks for that.... that is what i was looking for.

it was mentioned above several times about fuel lines not liking the b100 are there any replacement fuel lines out there that are not affected by the bio or is that just something that will have to be replaced from time to time..... i'd rather just switch em out and not have to worry about that.... thanks again for the replies.

The way I see it , or read it , he is going by what he has read & heard , not what Dodge told him or from some documentation .
But that is what most of us have to go by , it would be helpful if his reply gave better answers with documentation .
From what I have read / heard , is that most manufactures went away from rubber products about 94 , finding out for sure , and when is still what is in question .

cmac

one more thing.... kinda off topic but do you guys (or gals) know if there would be any mods needed to run b100 in a 2000 7.3L PSD? a buddy or mine has one and we were thinking about going in one one together if it would work in his truck too with little to no mods needed. thanks again for all yer help.

How many sources of cooking oil do you have in Afghanistan ?

cmac

actually you'd be suprised............






ok maybe not really..... we are just trying to get everything straight for when this deployment is over in about 6-7 months
