WVO Fuel lines

Postby sonofthesun » Mon Nov 16, 2009 12:49 pm

Okay. So I'm almost done with my install but I've got a question regarding hose line for veggie.

This site http://www.goodyearep.com/ProductListin ... derid=1036
says "not recommended for biodiesel" does that mean WVO too? Or is it the other chemicals that in Bio that break down the hose?

I have both 30R6 and 30R7 on the system. Do I need to replace all of it with 30R9? Or will the lines be okay with WVO?

Please help ASAP.

Thanks too all.

30R6 and 7 are fine with VO. Bio is a strong solvent while VO isn't.

Every fuel line I have read about sooner or later seems to break down with Veg or Biodiesel no matter how expensive it is for one person or another.

My very successful solution has been to use the plain cheap Vinyl re-enforced common garden variety hose and change it out as need be.

For me, this stuff easily lasts a good 12 months so I change out the 5-$10 worth every year when I do the rest of the annual maintenance. Not hard, dosen't take long and gives me the chance to check out the rest of the fuel system as well and spot any current or potential problems.

injector line vs. fuel line?

Postby Ontario » Thu Jan 06, 2011 2:59 pm

Can the same fuel line be used throughout the vehicle on a 12 valve 5.9?

I used all SAE 30R7 everywhere, in 2 different sizes to match stock sizes.

hose for VO

Postby 88tlc » Thu Apr 14, 2011 10:39 pm

not only is the VO a unique fuel, it is also very hot, and under pressure. i have used rated rubber hose, even a trident coast guard hose that was lined, but the hose will not last.

i would not use garden hose, and rely on replacing it. never fails this stuff will fail while you are on a road trip, and going to a wedding!

I have used the AN fittings and teflon hose or rubber hose with hose end fittings. the hose ends are easy to remove without trashing the hose, and the stainless prevents the pulsing from the liftpump, and hot oil pulsing through it. the fatigue will kill wimpy hoses in a year.

the ANfittings are expensive. but i like no brass, no steel, and build these systems once, and not have to worry about a leak, or air leak troubleshooting.
