Title: Routing the Fuel Lines, are they suppose to lay on top of the Valve Cover?
Post by: SaltLick on March 21, 2009, 10:21:50 AM
I got my tank back on, got everything ready to go when i noticed something. Are the 2 fuel lines suppose to just sit on top of the valve cover like that? When i lay the tank back down they both just run over the top of the cylandir. Wouldnt that get hot and melt through the lines? Is there something im missing or does that part of the block not get hot? I didnt take the fuel lines off or anything just took the gas tank off and put it back on, so i assume they are laying in the same place as when i took it off. just checking to make sure.

Bike?

I know on my carbed M900 the fuel lines don't lay on the engine.  OTOH, in general, a fuel line laying on a cylinder head/valve cover (as opposed to the cylinder itself) wouldn't be that much of a problem.  IIRC, fuel line is rated to 600Ëš.
Then again, I live in Las Vegas, so I try to keep my fuel lines as far away from the engine as I can to avoid vapor issues when it's 115Ëš outside.  (I just did a few mods and re-routed my lines as far away from the engine as I could)

Have you downloaded the parts and worshop manuals from Ducati.com?  There will be pics in there that show the routing of the lines.
(You're lucky, <2000 bikes aren't listed and as hard as I've looked, I can't find a parts manual and only found an incomplete WS manual for my '99)

My question wrt the parts manual was the routing, not the name of the part.  If it is showing you that your routing is correct, you're golden.

The owners manual and the parts catalouge dont show you how the lines are routed.  I dont see any kind of shop manual on the ducati website.

That sucks.  There's a pretty good pic in my ('99) OM.  Workshop manual as well.  Look in the back under "USA Models"  In mine there's a whole extra section WRT emissions stuff and it may be there. 
As far as WS manuals, there's a link somewhere here for a source.  In fact, I think someone is selling the CD's in "Parts for Sale"  Woops,  his CD for your model is sold.  FWIW, they are available from Ducati.
