Biodiesel Compatable Fuel lines
Posted: Thu Jan 24, 2008 2:41 pm
I think I've finally located an off-the-shelf fuel line that doesn't degrade with biodiesel.
I spoke with Jack about 14 months ago, asking what he recommended, and he (incorrectly it turns out) stated that all the new lines will handle it, so he doesn't carry lines just for it. Using that advice, I replaced all mine with stock stuff from NAPA.
Less than a year later, I had a gooey mess of nasty hoses that were just about to give out when I noticed.
After researching some more, I found that Goodyear has a line of fuel injection hoses that are all rated to handle biodiesel. I tried to find them in my local market, but wasn't able to. I sent an email to Goodyear asking them where I could find some, and they sent me a phone number to call that department.
When I contacted that department, they verified that yes, theirs would handle BD, and told me that in my market, Autozone and Carquest sold that brand. I went to CQ, but they told me that Goodyear must be mistaken... they do not.
When I went to Autozone they had it. YES!
It's not cheap (around $4.50 / foot), but you don't need much and you could tell just by looking at it that it's going to work! Be sure to ask for the FUEL INJECTOR LINES. The normal Goodyear won't work, and aren't the same.
These are different in that there's an inner lining of some sort of hard blue plastic. The lining was about 1/8" wall thickness. Surrounding the lining was a normal looking fuel hose, complete with the braid running through it for strength. It was also branded Goodyear all over the outside.
I used 5/16" for the engine compartment going from the metal lines to the filter and the 'out' side of the fuel pump. You really have to work to get it to fit over the metal firewall line going to the filter, but with perserverance and a few choice words it works. This is also the size of one of the two lines coming from under the tank. The other hose under the tank I used 3/8", but I'd already replaced it with a polyurethane hose I'd gotten from Fluid connector Products. It was a bit dodgy, but good hose clamps can work miracles.
I used polyurethane tubing for the injectors as well. It takes 1/8". If you use standard fuel line, 1/8" can be pretty tight. With the polyurethane, it's a pretty flexible line so it stretches easily. I would have used it instead of the Goodyear, but I couldn't find it in 5/16".
Hope this information helps someone! I'm not planning on replacing any lines anymore!
