A few things fuel related.

[activpop]

Update...ran all new fuel lines and installed new filter. Thank to Scud's compatible parts list finding the filter was easy. Airbox cleaned out and everything cleaned up. Connecting the last jack from the fuel solenoid I noticed one wire had broken off at the bottom of the unit. SO NEAR YET SO FAR! I know the solenoid unscrews from the petcock. I looked at my other 2001 sport and it doesn't seem to have a wired solenoid on the petcock. Why would that be? And more importantly, what to do now? I knew those wires were fragile and I took care but they are almost 25 years old.

No problem . Find a manual petcock along w/any o-rings involved and get rid of the electric one.

Just did a search on this. Seems to be a many faceted problem. Wonderful. I've got a plan.

Peeled out epoxy around wires to expose broken wire stub. Not sure I can get a good solder joint with what I have to work with. I'll try though. Ordered the manual one from MG. If it ain't one thing, it's another.

If you are competent , you can do it. Keep wires separated when you do the solder job and use silicone or something non-conductive to hold everything in place when you finish .

I can solder just fine, but the two wires are really close together and I only have about an 1/8" stub protruding.  I'll have to put a small heat shield between them. After reading about these things, I see how they are problematic. Such an important part with pansy ass wiring.

Not sure when Moto Guzzi went back to the manual petcock on the V11. Perhaps during 2001, but certainly by 2002?

The point at which the last fuse slot went dormant . . .

IF you have not located a manual petcock , I found a used one in my stuff. I was sure I had a new one. If you still need it , I can send it to you .

That's quite the offer. Thank you for that! I have one ordered from MG cycle, so I'll pass.  At least now you know where it is!

There is no better fuel tap than the Lucky Phil EZ-Glide mod . . .

Thanks for finding that procedure Docc . I tried looking for it yesterday and ran out of time.  I suppose the o-rings in the original manual shut-off valves had junky 0-rings and couldn't tolerate the alcohol content ? The only way to get quality o-rings  is from a good industrial supplier .

No they can't tolerate Gasoline contact. Not all rubber will maintain it's dimensions with regards to gasoline contact. A LOT swell which in any static sealing use is usually fine until you pull the component apart then you need to replace the rubber seals because you can't refit them due to dimensional change but in a dynamic situation such as the fuel tap spool the unit just seizes due to the seal swell. There are many material variations with Nitrile rubber and some is more Gasoline proof than others. Viton/FKM seals are the answer. Unfortunately you can't buy Viton seals of the exact dimension you need to replace the original seals so you need to modify the spool grooves.
