For those of you looking to replace biodiesel degraded fuel lines, I've found a cheap replacement, with the added bonus that it's clear. I've used Viton before, but it's very expensive ($15.26 a foot for 5/16"!) and doesn't hold up to vacuum well. Dayco Gen 2 (viton lined) is nearly impossible to find and is still expensive. It's unclear whether other fuel injection lines (Goodyear?) will stand up to bio-d. I know the NAPA stuff won't last two months (I think it was Gates brand). The stuff I found is clear ether-based (as opposed to ESTER-based) polyurethane. It's the stuff biodiesel homebrewers use on their reactors. I just bought a 50' roll of 5/16" from McMaster-Carr at $0.78 a foot! Plus it's clear, so it's easy to diagnose fuel problems, and it's vacuum rated. Just got it the other day, looks like good stuff. I've haven't personally used it yet, but I've seen testimony from others who've used it for years with no problems. Just thought I'd put it out there.
No announcement yet.
