Fuel leak on start up

[Jeriatric]

Common denominator was mid to low 30 degree tempratures. Cold start resulted in fuel dripping off the bottom of the engine, two mornings in a row. Once the engine warmed the dripping stopped. I know, I'm lucky that's all that happened....Day one I was not ready when it happened. Day two however.....we were ready. Had a big bag of marshmallows and extra long sticks to skewer them with.

Seriously now. Am thinking it was unused fuel being directed back to the tank from the throttle bodies. If so, I have no idea if it was leaking at the throttle bodies, or perhaps at the fuel line connector at the tank....or?

Has never happened before but, it has never been started below 50 degrees or so in the past.

Any ideas?

This is no time for guesswork. Strip off the body panels and inspect carefully. The fuel system is a closed system, and there are no overflow provisions. Any return is to the tank. Likely culprits are loose fuel hoses or a failed fuel filter. This is a serious fire hazard...all joking aside. Find the leak before you ride again! nojoke

Closed loop - not so closed

Just a little humor from the dark side. Sometimes that's the best way when things get serious. Least it is for me. My dealer gets this one cause it's fairly obvious parts will be needed and am pretty sure it's a warranty situation.

Folks, I'm in total agreement about the seriousness of something like this. Don't try it at home. But, if you do. Hope you have marshmallows close by. :doorag:

Marshmallows cooked over a gasoline fire have a gassy taste that lingers on!

gassy marshmallows - sounds yummy. pps:

Good thing that this leak was found before it started burning the tupperware and all of the farkles. Hopefully you can trailer the Spyder to the dealer so that another cold start and leaking gas can be avoided.

BEST PLUS WARRANTY - should cover it. Will know soon enough.

Leaking fuel..!!

nothing to ignore but sounds like engine heat swells up some connection back up stopping the leak. If possible pull panels and see if you can spot the leaking culprit. Could be an easy fix but if not off to the dealer for sure...:lecturef_smilie:

My thought exactly. Only hope the dealer can duplicate the problem. Unless of course it's something that a little pushing and/or pulling exposes.

Lets us know what it is/was.

This weekend I will be doing my 4500 mile oil change and I will be doing it the BRP way pulling all the panels off. Reason is, is to inspect as much as I can and how things are looking under the covers (oh and also to add some farkle that requires the panels off).

Best guess, it will be a connector that expands once warmed a bit. Tho, that's just a hayseed guess. Know for a fact they have been found defective in the past, and it is not a problem that is exclusive to our spyder. Rather another instance of "value engineering" that all manufacturers resort to. On fuel lines no less. Go figure!

Yes I have read posts of that happening. I plan to check those along with looking for dry vacuum lines, radiator line clamps, general chaffing of hoses and harnesses, etc... I will also probably apply some 100% silicon lube to hoses, etc to help keep them from drying out and cracking.

Oh and I do plan to adjust the belt myself and also will be installing the smooth spyder belt idler! :2excited:

PM your mailing address and I'll mail you a length of silicone vacum hose. You'll need to cut to length.

3 & 11/32 each.

Hey, it's a small token compared to your contributions here. You're welcome :doorag:

That gas you're smelling may not be associated with the evaporative canister system.

Thanks I will check this when i have the covers off this weekend!

I get gas smell now and then and also assumed it was the canister.

Bob

P.S. the new vacuum hose arived yesterday. Thanks Jerbear!

It could be loose connections on one or both sides of the filter. On startup there is a surge of fuel pressure and a little will escape from the ends of the hose until the clamp wedges itself against the collar of the filter stem. Look for discoloration from the spray on the evap can. This happened to me.

Good advice. That was one of the three places mine were leaking. The other two were fuel tank quick disconnects.
