Although I've not had any error codes, the fuel pump on my XTX will sometimes whine when turning the key on when it's cold out or after I've filled up the tank. I bought a used pump that came out of a Tenere on eBay for �25 last summer and planned to fit it this winter but still haven't got my winter hack ready so the XT is still in use.

When I do get around to it though I'm wondering whether I should replace the o-ring between the pump assy. and the tank. I know I should really but it's �20 from Yamaha!!!

replace but take original and if poss any parts that it fits to a bearing/transmisson place..if it costs �1.00 you either been robbed or got a bargin..

you do realise Yamaha don't make O-rings ?
they buy them just like you can...

the one i put in my XTR cost around $5 NZ..

84mm dia & 3mm section.. be sure its suitable for use with fuel...


..

The internal part of the fuel pump assembly (the actual pump) is identical for all XTs and the MT-03. So yes, this one will fit.

Brilliant! - thank you!!! Is that 84mm ID or OD?

Pete, was it definitely a 3mm section? I ordered a couple of these o-rings the other day but found the section was smaller than on the original - it didn't look like it would seal properly so I ended up reusing the original o-ring.
