Fuel feed pipe O Rings

Joshua Brew · 10-05-2020, 05:12 AM

Hi all, one of the black o rings is damaged on the return line from the fuel tank. There are two rings, one brown and one black situated on the push connectors that sit under the tank. Does anyone know if I need any special O ring that’s specific for fuel applications or can I just source a standard o ring.

They need to be viton o rings

These list 1100 monster, not Evo specific but I imagine they would be the same connectors used on most:

You've a choice of at least three sources, Joshua:

Although Ducati don't list them separately for the Evo, part no. 88641181A is listed as the fuel pipe o-ring for, among other models, the ST4, 748 and Monster 900, and works on the 696/796/1100 Monsters too.

The Triumph equivalent (T1240181) is identical and also works. Although it's black, it is viton, (I have the email from Triumph's technical department to prove it!).

Here's a comparison between the Ducati and Triumph rings (green - Ducati; black - Triumph).

Then there's the CCA o-rings that Darren linked to but they're about seven times the cost if the genuine Ducati items.

I've got some spares so, if you PM me your address, I'll pop a couple in the post tomorrow.

put a light smear of grease or chain lube on your finger and wipe round the o rings before plugging the pipes back in, this will ease them in and reduce the chances of tearing one.

If you look on ebay there's a set of 10original Ducati green ones for £10 which maybe worth a punt?

As Rob suggest's some grease is a good idea as most failures come from ham-fisted connection/disconnections, rubber grease would be good if you have some but any is better than none.

They'll be in the post tomorrow, Joshua, together with a sachet of rubber grease.
