Title: Replacing quick release fuel connections - advice?
Post by: stopintime on June 24, 2014, 11:25:08 AM
My S2R threw fuel on my leg yesterday - engine just died, my leg felt cold and I could see fuel pumping out.

As expected the quick release connector's ring/tab is broken and it won't stay in place.

New being picked up tomorrow.

Any advice about this job - just plug & play?

No problems getting them out and in?

The times I have taken them out no issue, issue might come pushing in . . . I really push them hard and just give a key on to make sure no leaks are present tanking them out at times could be "sticky" . . .

is this the first time you are replacing them? asking because of the particular design of the hose clamp

Yes, first time - at 108,000 km - 2007 model.

I didn't study the clamp in depth, but I remember it as a normal clamp with a bolt to screw out and in.

A little bit of WD-40 on the O-rings prior to install makes it a heap easier.
You can use grease, and if you're just putting a little on, it's fine.

OEM they seem to use a lot, and the generous surplus on the outside grabs every bit of dirt and debris it can.
Which is really not helpful.

Get a couple of O-rings too, they're rather delicate.
I replace quite a high percentage of 'em.

Ive had bad luck with WD40 and o-rings. The best thing would be to use a silicone lubricant made specifically for O-rings, failing that I would use chain lube. WD-40 just isnt great for O-rings (which is why you dont use it to clean/lube a chain)

I've used a super thin coating of petroleum jelly (classic Vasalene) - get some on your fingers, rub it around (ahem) so there's just a coating, no gobs and then just transfer to the o-rings, barbs etc - easy peasey

Thanks - after a Vaseline detour - mmmmmmmm nice  :D

.... I fixed the actual job. No issues, straight out and almost straight in. Nice and tight - runs - no leaks yet.

Plastic ring that tighten the locking tabs was broken in two places.

Too tight hose clamp?

Don't recall the particulars but as a test one of the inmates over at advrider soaked some chain type o-rings in WD40 for a long time with no deterioration or swelling.  His conclusion was that WD40 is harmless to o-rings.  Fine for cleaning chains, just not much of a high load lubricant.

I think the problem with WD40 and O ring chains is not compatibility.  More likely if doused with WD40, verses conservatively wiped, the WD40 can seep past the O rings, a washing out the lube.

Get a set of these quick disconnects and you'll never have to worry about an O ring.

Cool. At least you can torque up the clamps and not crush the fittings.
