Fuel lines for Biodiesel.

Postby nucleus » Tue Apr 09, 2013 10:45 pm

I posted this over in the diesel performance mods and upgrades but also wanted to let anyone using Biodiesel know, there is an alternative to expensive Viton fuel line. Tygothane tubing is Biodiesel safe and rated to 200F. It's a little over a dollar/foot, and it's clear so one can easily spot air leaks should they develop. Not to mention it looks cool too!

I like the new fuel line.

Where are you purchasing it?

I work at a biodiesel refinery. Its brand new and I believe we are most technologically advanced producer in the world; meaning we are not using the standard batch method. We make b100 continuously 24/7. Over the weekend a filling line and green gun-nozzle (like you'd see at a gas station pump) was installed. Employees can now use our product free of charge (except maybe tax). So now I'm getting on the installing new fuel lines. I was gonna get these http://www.dudadiesel.com/viton.php. But today, my fellow maintenance worker said stainless steel tubing would be the best. I work with this stuff all day long so I can source it, bend it and connect the lines using swagelok fittings. Has anyone tried this?

Fuel lines run between several independently-vibrating components, especially in the engine compartment. SS would be nice for the long run from the tank, but you will still need flexible lines to attach the parts.

Gus, thats awesome! I also work for a commercial biodiesel refinery.
I'm the Production/Plant manager for Piedmont Biofuels here in NC. You may have heard of us. We commissioned the first commercial enzymatic transesterification unit and had quite a lot of buzz surrounding that project. We are also hosting this years CBC conference in August. I know its a long way from you….but maybe you can make it out!
If you haven't heard of us, check us out www.biofuels.coop

Keep on making the good stuff man!! :D

Same part #'s as what I have been using since I originally posted this.
No issues with sweating yet. They still feel the same as they did a year ago!

I'm about to order these lines. Why 25ft? Wouldn't 10ft suffice for both sizes?

I ordered the tubing listed above and installed them last week. I've been through one tank of b50 so far. Smells different but the performance of the truck was just as good maybe even more fuel efficient. I got another mile and a half more per gallon, but other factors were at play so I'll have to wait til the next tank.

When installing the new lines I ran into the problem of the smaller lines having too large of an inner diameter. The old lines were less than 1/4". So I ended up using another larger tube as a bushing so that my hose clamps would work, otherwise I was having leaking issues. I couldn't find any hose clamps smaller than 1/4". For those of you who have been using this tubing, how did you make it work and secure the lines without leakng? I might just order another size from mcmaster carr. One with a smaller id and a thicker wall thickness.

I looked the #s up on McMaster-Carr and they are rated for 175* F where did you get 200F from? I and run biodiesel and SVO so I need a higher temperture rating.

Direct from the manufacturer. They state 200F. Not sure why McMaster Carr says 175. https://www.professionalplastics.com/pr ... -C210A.pdf

Normal operating temp for your engine should be around 190-200F. If you are using an added coolant loop through a secondary tank to preheat your SVO, then it won't be hotter than 190-200F. You'll be fine with this line. I've been running it for a year and a half now with zero issues.
