Just a thought on the many threads describing stumbles, no-start and a myriad of other potential fuel supply related posts. Has anyone considered/researched the ethanol being added to our fuel? In my experience in the marine industry it causes a ton of problems particularly in older fuel systems by dissolving deposits in the system and sending them downstream to pumps/filters/screens, etc. Most horrific is the fiberglass fuel tank where it actually dissolves the resin in the tank and sends the sludge downstream!! The USCG industry specs for fuel hose have also been updated (years ago) to adapt lest your fuel hoses dissolve. We have a case of filters for our fuel sales pumps and have been advised to "replace at least once a week for the first month or two" after we have switched over to the ethanol spiked fuel. Comments?
