    Tygon Oil Lines

    I ordered Tygon PVC tubing thru McMaster Carr to redo all of my oil lines on my opti. With the Tygon tubing straight runs are good, even some moderate bends are OK but down by the oil pump the hose seems to kink a bit if there is a sharp bend. ID of the Tygon is good but the wall thickness is a bit thin. This is what I ordered:https://www.mcmaster.com/#5552k23/=1bs8s26Are there any cheap alternatives to the OEM stuff?

    It's okay for bleeder lines. I've used high quality fuel line for oil injection since the first clear line I saw rot/break/fail forever ago. I really don't care if I can "see" the oil in the line as long as the oil pump primes and bleeds properly. Sleep is much better at night knowing the hose will last.

    Didnt think about bleeder vs injection. Still learning, thanks!

    I've been using Tygothane for fuel and oil lines on my ultralight/Rotax oil injected motor. It holds up better than anything else I've tried. I even use it on my 5 gal. gear oil buckets...stays pliable. Here's the line I use. https://www.mcmaster.com/#catalog/124/157/=1bseinh , the formulation I use is the C-210-A....I never had a problem with tight radius's either.

    So my concerns with the thinner wall Tygon tubing were overrated. I replaced all of my oil/bleed lines on my 08' opti as they were all original. Some of the bleed lines were a bit chaffed and brittle so a good thing I went thru the trouble to change them. I'll change them out in a few years and go with the abrasion resistant lines that DanUmbarger posted. The tubing in the pic is McMasterCarr # https://www.mcmaster.com/#5552k23/=1bs8s26
