Title: Replacing the pre-formed fuel hoses from a carbed Monster
Post by: Rudemouthsky on May 20, 2015, 06:28:41 AM
How have you guys done it? Did you pre-form, re-route, or just buy the correct part $$$ from Ducati? I really under estimated how much of a pain in the ass this was going to be.... [bang]

looking for some fresh ideas and perspectives...gotten myself extremely frustrated here and that's not good when working with gasoline, lol.

Don't know if you have already considered an internal spring at the bend locations to eliminate kinking.

Spring mandrel, bottom right corner page 10.

Sorry for the size of the catalog. They have a smaller one which only has fuel line supplies, but I could not find it in the rush to be the first reply.  ;D

I don't have the bike anymore so i can't do more than the existing photo, but here it is:

Not using the vacuum shut off gave freedom to rout the lines differently.  I did use the stock filter and common automotive (read thicker) fuel hose that doesn't kink as easily and holds the petcock fine without a bracket.  The hose from the pump to the carbs is also positioned to be in a cooler area.   On your bike you probably want a nicer petcock, maybe one from Pinglel  http://www.pingelonline.com/Fuel-Valves/inline.asp (http://www.pingelonline.com/Fuel-Valves/inline.asp)

If you do use a standard fuel line (non-pre-bent), be careful to keep it away from direct engine contact.  I have had to wrap that fuel line in a high-temp sleeve where it made contact with engine parts in order to keep the fuel from boiling at those contact points causing vapor-lock.

YMMV:  I live in the high desert so heat here is a BIG issue.

Well there's just no way that's gonna happen. I'm just gonna have to hope my engine never gets that hot. Think I finally licked This but maaannn was it a royal pain in the ass.

FYI; the 1/4 and 5/16th rubber fuel hose off the shelf from Advance rocks. Stuff is capable of 180 degree bends it's a joy to work with. Puts the expensive Italian made Ariete stuff I bought and the stretchy OE hose to shame. American made rubber got-dammit!
