My HJ-60....She is now a vegetarian

[In2cruisers]

Got her running on B99.9.... 80% cornola / oil 20% soy oil. Buying it from a local Alternitive fuel station....Diesel reciently went up to around $3.18+ a gal. And the B99 is $3.14. Lately around here, gas went down, diesel went up....go figure.
Any hoo, She runs like a top on that sh#t. Been getting mixed results with diesel arond here lately. Wish they had better standards for diesel.....but for now she'll stay a vegie burner. Cant wait to see how she runs on that stuff once I install her pace maker (TURBO)

[Winslow]

Nice work. I did the same. Carry a spare fuel filter. My tank/lines had a lot of crap in them. The injection pump seems to dig the B99 as well!

[JohnnyBoy]

just did the same, milage is down a bit but well worth it.

[Canuck]

Did you guys change the rubber fuel lines? Whenever I fillup at my regular place the guy is always trying to convince me to fill with B5 saying that it won't harm the rubber fuel lines.

I think its been said on the forum that you can run up to B20 without any worries at all.

I've been running B20 from the Norland UP cardlock for several months now and I haven't had any issues with it yet

[Mountain Goat]

B99 will eventually eat up your rubber parts. That is fuel lines and IP seals. It takes 6-12 months to really cause a problem. Watch for softening of the rubber. I gets squishy and starts to "weep".

I've been running B20 for a while without any problems (other than less power and fuel economy), but won't go higher until I can do a proper conversion.

Unfortunately Viton and IP rebuilds are pricey.

Can anyone substantiate failure of other fuel system components due to ASTM spec biodiesel?

I Can!! (not to be taken out of context - used = used). One of my HZ's is dead - diagnosed cause = biodesiel, ASTM certified fuel, Bend, Oregon. Oregon Fuel Injection and my mechanic made me promise not to run biod. in the 2nd engine.

Three years later I'm at B-10, we'll see. I have not gone back through the bad engine yet, but it did have a broken ring and rust on all 6 pistons. So, while things may be blamed on Boid., it may have nothing to do with that particular engine failure.

A lot of money and hassle later, I'm slowly moving back to biod.

Bio could not have been the culprit. A broken ring and rust on all 6 pistons sounds like water got in there. Bio SURELY could have een contaminated with water, but that's not bio's fault, that's a quality control (or filter) issue.

I have been running B100 for nearly 8 months, no new issues, no apparent weeping of lines (though I am swapping to Viton soon, just because).

[ylexot]

I second John M Galt's question: Anyone experience a breakdown of fuel lines due to bioD?

I ran B20 and B99 in my BJ for about a year with no issues but a precautionary fuel filter change after a few tanks. I understand the theory of bioD being a solvent, but can anyone confirm the fuel lines, et al., can be dissolved by the fuel?

[Canuck]

I remember reading a how to on this guys page and at least on a 3B engine, switching to new lines doesn't seem like a huge job.

Old "rubber" will be affected by high % biodiesel, there's no room for debate on that.. The question is, what "rubber" was used in 3B and 2H motors...
I don't know either. See this: http://www.biodiesel.org/pdf_files/f...patibility.pdf
And this for sourcing tubing: http://www.mcmaster.com/ (click on "tubing" (the 5th link) under the fist heading (Fittings, Pipe, Tubing and Hose).

What I DO know is that when I ran Sheila on dinodiesel, the fuel pump had no leaks that I could detect. I have been running B100 for a while now and now my fuel pump is wet on the outside... My hoses look perfectly fine though.
What's the fuel pump gasket made of? I suppose a rubber-like material. I might have to fab a new gasket from Viton sheet.

[Tofudebeest]

From McMaster, to fabricate Viton gaskets:
(I am unaware of anyone making Toyota viton fuel pump gaskets--or O rings for that matter).

Not to scare anyone...

I've been running B99 exclusively for 5 months. I bought the Viton lines 4 months ago but haven't actually done the conversion yet. I check my fuel lines religiously and so far haven't noticed any adverse effects at all -- nothing but good experience here with it, but then I'm probably on the short side of my rubber lines' lifespan at this point. I also change the fuel filter much more often but I'll ease up on that as my fuel system should be completely 'flushed' by now.

It all depends on the condition of your rubber fuel lines when you start running high % biodiesel. I'll post up pics of my lines when I get around to the Viton swap in the next couple of weeks, but I don't anticipate any noticeable degradation. There's no doubt the B99 will eat the rubber over time, but it's not an overnight process. I don't think I'd worry at all with B20 or less.

This is just my experience so your mileage may vary. I think a huge factor is the quality of the fuel you have access to. Here in Austin biodiesel is very popular and I know the source, but on a road trip I'd probably fall back on petro diesel before going with an unknown source of biodiesel.

Talk to people in your area, possibly a co-op, and get first-hand accounts. Good luck!

Zander's on the boards...
http://forum.ih8mud.com/members/zander.html

A wealth of info on his site too.

[integrin]

Yep, zander's site is where I got the numbers for the Viton lines. He's all over this stuff.

Changing the fuel lines is even easier on the 2H and 12HT since more of the lines are steel with only 3 feet of rubber to replace.

I'll post a thread when I get around to doing this.

[Mountain Goat]

Costs more than dino or bio around here.

I have to admit that I have not seen any adverse effects from using bio in my truck. I have filled with B99 a few times. It also should be noted that since mine is a conversion, I still have the gasser fuel lines. It turns out that most of the fuel system plumbing was the same. So my lines are likely different than your anyway.

I'm surprised to hear that anyone from Oregon Fuel Injection would diss bio. They should be better informed. Even Cummins has certified their engines for bio use.
