6.0L and Bio-Diesel - Diesel Forum

jobremski · 09-28-2006, 10:38 AM

Anyone else out there running B100 or home grown biodeseil on the 6.0L?

I'm making a good gas as far as I can tell: it's clear, viscosity is good, color is good and PH is correct according to all the reference material I've been reading. I've been making it from WVO for about a year now and truck has been running and towing perfectly.

Now my problem is I had a fuel pump die about a year ago. I thought nothing of it, hey $#!^ happens. Well I'm experienceing the same symptoms of a bad fuel pump again and now I'm wondering if my fuel is causing it.

Is there anything in the fuel pump that would react badly to biodiesel?

I'm mixing 20% SVO with 80% Reg Diesel, Had no Problems!

Almost always B-100 for about 14,000 miles. That about all its run on since new. Home brewed. I will have to start cutting it with reg. diesel soon as the temps start to drop. I see I will have to change my signature, it says B-50. That was as much as I could squeeze in the first day I brought it home.

Awesome news, I've run about the same miles thus far on biodiesel so this is leading me to believe the fuel pump issue is not something I caused.

Thank goodness, I did not want to have to stop using it as I don't see how anyone can afford $3/gallon diesel plus the fact that I have 2 1/2 barrels already made in the garage [img]/ubbthreads/images/graemlins/smile.gif[/img]

Are you making your own biodiesel or using store bought?

Did you already have your fuel pump changed out? I am assuming you are talking about the frame mounted pump.

What symptoms are leading you to believe its the fuel pump?

Not yet, I dropped off at the shop to have it looked at tuesday and they have not gotten to it yet.

Are there 2 pumps? That would explian alot! Lets say your on the freeway or towing and you start giving it fuel. Sometimes it will just go then out of no where no matter how hard you push the pedal you get no more go. In fact it will start to buck and vibrate violently if you press the pedal to the further as if the truck is opening up and also giving it more air but now you leaning out the mixture and it starts to run even more pourly.

Going down the freeway more recently it almost seemed like a switch being turned on or off. Loss of power then click I have all the get up and go in the world. Then later on again out of no where back to only able to hold idle. The 2 fuel pump senario might be exatly what I'm feeling one of them, the one on the frame rail, like turns off.

I have also noticed when the truck is off and in the driveway and you turn it to on I do here 2 differnt noises. The one under the truck instead of having a nice constant high pitch noise has had a not so constant sound.

My other theory was a screen or something in the fuel tank that is clogged but the all of a sudden on/off feeling of power or no power seems to sudden, I would expect a clog to be gradualy less and less power till nothing.

Yes there is only 1 fuel pump, I was thinking of another fuel system when I asked that. Sorry for the confusion.

How often do you change your fuel filters? Bio has a way of loosening up all the crud in your fuel system which will prematurely choke your filter.

jobremski · 10-02-2006, 02:25 PM

I had a similar occurance a while back and when I pulled the filter out I had a suprise of a gel like substance on the filter but this was after a not so good batch of biodiesel that I ran anyways. Changing the filter did fix things after this occurance but the loss of power that time was gradual and eventually keep getting worse and worse until I changed the filter.

The crud problem is usually after the first tank or two so after about about 700 gallons of biodiesel (according to my records) I would think this problem would be over. Though I did change the filters just to be sure.

I had the same problem!!! Check your connections on your Juice module. I have a '00 with the juice/att combo. I was having the smae problems. Thought it was CPS replaced that and still happened. Removed the Juice and all is well, have an RMA to send it back to Edge now.

jobremski · 10-05-2006, 01:14 PM

Well got word from the shop and they said it's a contaminated fuel problem. I told them I'm running biodeisel and they said "Ohh no the 6.0L does not support biodeisel, it messed up the pump, a fuel sender and messed up a few injectors....". Then goes on to tell me this is now a user fix $1300...

I have been running biodiesel for at least 30k miles like a few others have stated, could what the tech be saying true?

I called Ford Customer Care number and besides getting a tard that did not even know what biodeisel was they suggested not to use it because "biodiesel is a blend of diesel and biodiesel and you usually do not know what the blend is made of". Well I could tell I was not getting anywhere as I know what my biodiesel is made of, I made it!

HFCM · 10-05-2006, 03:24 PM

Unfortunately what the tech told you is true, the 6.0L and I believe the 6.4L are only "validated" for use with B5.

The injector failures may be a result of low fuel pressure related to the pump problem.

Do you have run the truck with B100 for 30K or is that the mileage on the new fuel pump?

jobremski · 10-05-2006, 04:26 PM

Here is kind of my history as best I can remember:
32k miles - bought the truck
34k miles - had three injectors replaced (Under warranty)
38k miles - started making and running B100
42k miles - had the first fuel pump die ($100 under extended warranty)
55k miles - had a tranny issue broken sensor broke something else ($1300)
57k miles - Bad sensor and waste gate something or other on the turbo ($100 under extended warranty)
60k miles - 2nd fuel pump, injectors and some other issues that I need to have explained to me still. ($1300 is the esitmate so far)

So only about 18k on this pump and 22k on the motor since starting to run biodeisl.

Joe,
Did you get the e-mail I sent you?

jobremski · 10-05-2006, 05:47 PM

Hmm, no I didn't see it come through.

i had a 2005 6.0 black dually slammed on 24.5" alcoa rims shaved to 24" to hold low profile tires. The truck was stolen from my driveway a few months ago, my florida sun pass was used and i tracked my truck on its last toll exit 2 blocks from dj-performances home (Domingo Jiminez) He had my truck for 1 week putting head studs in it 2 weeks from being stolen.... kinda makes you think right? well when domingo removed my motor for the head studs, he told me my motor was the best looking motor he has ever seen, he said it looked as if it had less than 1000 miles on it. It had 40k on it, i ran home brew b-100 for 30k. He said the injectors were super clean and the pistons/cyl walls/everything was perfect, better than he ever saw. The only problem i noticed was, do not run a water block filter with svo or BD becasue it is proven that wvo or bd will saturate the cotton in the water block film, causing the filter to plug. I believe the wix filters use the outer white paper like wrap as the water block, not the actual element unlike the motorcraft filter. My motor was a true test. I never had a problem except i changed the lift pump once from running a plugged filter too long. I ran the hell out of the motor too, all was great. BD created a little less power but ran quieter. I never had a problem. Now after my theft i have a 2002 7.3. I got it since people bad mouthed the 6.0 so much. But i never had a problem, i ran dj's looney tune as well. Now i am doing the svo thing with the 7.3. I am not lieing or overspeaking my self at all... here is my old set up www.chrissommer.com/biodiesel1.htm if anyone wants my bd set up ill give it to anyone for $300.00 you just have to come take it... over $2000.00 invested.
