I found a problem with my fuel line last week on my 2000 model 13' Sport. I noticed the primer bulb would not get hard while priming the fuel, so I decided to replace it. When I removed the primer bulb I noticed some brown flakes that were similar to dried varnish on each end of the primer bulb. I went ahead and pulled the fuel tank and motor connectors to flush out the entire fuel line. Much to my suprise I realized a brown inner tubing inside the silver fuel line had pretty much disinigrated and was coming out in small sections as I ran water through the line. I checked the fuel filter on my 40 HP EFI and found several of the small brownish pieces in the filter. I went ahead and replaced the fuel line with a high quality marine grade fuel line and after putting the primer bulb and both connectors back together I flushed the fuel line between the motor connector and the fuel flter several times until no more small pieces of the bad Mercury Marine Fuel Hose were left in the engine fuel line. After replacing with a new fuel filter everything is back together and seems as good as new. Is this common for a fuel line to go bad after 6 years? Just curious. First time in 30 years I have ever see one go bad. All the pieces I saw were big enough to be stopped by the fuel filter but maybe if this had not been caught the line itself could have eventually been blocked by pieces of the inner fuel line as it continued to come apart. Has anyone else ever seen this happen. Thanks

I have seen this quite often with Tempo fuel lines but never with Mercury or J & E.
