Does anyone have suggestions for replacing the injector return lines when using biodiesel? I've been running up to B100 lately, and it has taken it's toll on the rubber/braided covered injector return lines.

I have all new synthetic fuel lines everywhere else, but haven't found a good substitute for the looped return lines.

What are you other biodieselers doing for injector return lines?

I used Viton lines, they are awesome a little spendy but fit just like stock.

What size viton lines (OD & ID) are you using, and where did you get them?

I just replace the cloth lines every so often. In my experience the viton lines get hard with biodiesel use.

They don't sell viton at Fastlane, so I sell it.

i buy new oem lines and replace them as needed like jason 15 min and you are done. have been running b100 for 6 years and replaced them only once.

Likewise... I had to do them once on my TDI (it uses the same line). But, I don't use B100 all that often, usually just B20 or B10.

I noticed the age of your car and couldn't help but wonder if old age wasn't hard on your lines. I didn't use biodiesel in mine, but yet at the same age had to replace the lines. Since I replaced the lines I have used a lot of biodiesel (B20) and have had no problem with the OEM replacements I put on.

you can get weedwacker fuel line at any REAL hardware store for about $1/ft. it is clear line, works great. may not look right to some, but they can use something el$e.
I think 3/16 fits well.

Hi, can someone please tell me if replacing these lines is a quick job? How do you pull the return line off injector? It seems like it's straight forward but I don't want to learn on my mistakes

Its very easy. You pull the old line off and push the new line on. The nipples on the injectors have a barb that holds the line on.
