Two bleed lines on my Mercury M2 240 EFI became disconnected; one disconnected fitting is located directly underneath the flywheel, right behind the trigger harness (viewed from stbd side); the other fitting is behind the VST on the port side. Tried to replace both lines with Sierra bleeder hose (ID = .090; OD = .220) which is a replacement for Mercury bleeder hose (32-99130122) but could not get the hose over the fittings...even when I dipped the ends in a little Premium Plus and softened with heat from my working light bulb. Based on recommendations I found on some boating forums, I tried using Tygon F-4040-A fuel line (3/32" ID X 3/16" OD) and I was able to replace both bleed lines with that. It was much more flexible and is designed to work with most fuels...here is the spec sheet: http://www.tygon.saint-gobain.co.jp/pdf/TygonF4040A.pdf. Am I ok using Tygon for this application? Also, I took the boat out for an optest after I replaced the bleed lines...operated from idle to WOT for about 20 minutes and I didn't find any leaks; but I didn't see any fuel in either of the bleeder lines and I'm wondering if this is normal or indicative of another problem? Thanks in advance.
