Fuel pump help request

Hi Guys

The power wires going to my fuel pump have frayed and a small..very small amount of gas is breathing down through the power cable and I am worried it might trickle on to the hot header with much more catastrophic results.

The local Ducati dealer who I trust and has serviced the bike for the last 2-2.5 years said a Ducati original pump is $1100!!

So, two questions:
1. Is there a cheaper, as good, fuel pump solution?
2. Is this a common problem and are there fixes that folks have already done? I searched the forum but couldn't find a concrete answer

Thanks.
PK.

Hey,

I replaced my fuel pump as it was beginning to fail but I did not replace the fuel/flange. I'm pretty sure it's part of the whole unit? Maybe you can try using some sort of fuel resistant sealant?

A two second search on the net brought up a lot of hits for a "sport classic" Ducati. First of all, what bike is it? Secondly, take the thing out of the bike and look at it. On a bench. With tools. Does it come apart? Is it a 25 cent gasket? What made it leak in the first place? What failed? Can somebody rebuild it? If not, is there a reasonable replacement direct from the co that made it? Are the manufacturer nomenclature and numbers on the casing? You can't be the first guy on the planet asking this question.

Do some research and before you blindly "goop it up", whatever that means.

Thanks for the advice guys. I will definitely look into the CA Cycle works solution. I will call them tomorrow. I explored using a better sealant but since the wires and sheath are frayed I want replace the assembly anyway.

Lot of the research I did on the fuel pumps pointed to seal issues I came across just one thread on the electrical issue. Even there I didn't see the fuel drip problem. I really want to get to a permanent solution because of the potential catastrophic outcome if the fuel drips on the top exhaust header. I am also going through the Ducati parts fiche to see how they have solved it in other models. But judging by the text on CA Cyckeworks' website it seems like an endemic problem on most air cooled Ducs

Cycleworks confirmed that their kit does not work for our flanges.

I’ll try Hypermo’s suggestion in my thread https://www.ducati.ms/forums/77-spor...p-grommet.html

Oh man. That sukks. I was hoping CA Cycleworks had solved it. I don't want to spend $1100 on the whole assembly.

This was what Chris told me

“Thanks for writing! Sadly, no. Your wires are of the smaller, more solid plug than the ones we're dealing with. The plug is held in with a circlip... pop out the clip and then push the plug to the interior side of the flange. To get the wires through the flange, you need to remove the connector. To do that, reach in and pluck out the color retainer piece with a small pick or bent piece of safety wire. Then you use a typical contact removal tool to get the contacts out of the connector housing.

You can then try changing the o-ring on that connector's plug...

Thanks,
Chris”
