1999 OEM Mercury fuel line. Lines are getting changed (obviously).

I split the line with a knife and separated it with a toothpic.

Question is: Are there any fuel lines that I can replace this with that won't do this?

[Glenn]

Yes, EBM line.

J/K!

Interesting, I have a short piece of new merc line and I can see the plastic liner inside it too.  It just isn't separated yet.  Is that from ethanol or what?  You'd think they would learn from this and make something that works.

Do I sense bias against Mercury products? I have had the same Mercury fuel lines on my boat for sixty-eight years and have never experienced a problem.  Would I lie? 

[ChrisAW]

I had the same problem with the lines on my Johnson 30 horse. Truth is this can happen with nearly any fuel line, just depends on the conditions they've been exposed to over the years.

Does your boat run on vegetable oil Mike? 

Is it Merc?

Is it age?

Is it ethanol?

:-/ :-/ :-/

[fishn hard]

It is ethanol that caused that if you go to your auto  parts store and ask for the ethanol resistance fuel line they should have it   

[5bass]

Yes, EBM line.

....said the guy with the new Yamaha    Was there something wrong with the old one? I cant seem to remember.  <----thats Glenn

Ha ha!  Good one Scott!  Naw, the problem we had also knocked out 7 Mercs and 2 other Yammi's at the same time in our area --> Ethanol.  I suspect the same issue is at play here, but I'm no mechanic, so I'm just speculating.

Uh Glenn,  whaddya mean "knocked out"?

Blown engines.

I have been reading about this lately. It is the ethanol. If you use a mercury fuel line get the gray line with red lettering on it. It seems there is a lot more ethanol than there used to be.

Here is a good thread about it.

Been there, read that.  Excellent thread on this subject.  Thanks Yankee. 

Incidentally, the "expert" on that thread is a guy named Don Weed.  He's from European Marine in Greenville, SC.  He is awesome on all things Mercury.  He has helped me out several times and he's been right on the money every time.

[Dam Yankee]

I have heard nothing but good things about Don. He has a great reputation. I don't know how many will take his advice but, I can assure you that I am changing my lines from the tank back.

I know this is an old thread, but I just encountered the problem, and, just found this thread.

This is the same thing I found in my 2003 Mercury 150 EFI. I thought I was seeing bits of varnish in the fuel system, but it turned out to be plastic

Richard at Mare Inc. in Thurmont, Md. explained it all to me today after I just happened to mention seeing varnish in the fuel line.

And this afternoon I check my email and find BoatUS is reporting on April 2, 2012 EPA has taken the next step to putting E15 on the street

I've got a 2003 Ranger 185VS, am I looking at changing out my plastic fuel tank, and black rubber fuel lines as well??????
