Dripping Gas (everyday) - Fuel Tank VENT hose.

[OhioFJR1300]

JUst so you do not feel alone with this problem, my '05 did the same thing. It was always leaving a small mark on the ground and it was indeed gasoline from the vent. My fix was not cheap but it did solve the problem . I traded my '05 FJR for a nice new '06 FJR and I no longer have the problem. My dealer was not able to offer any solution to the problem with the '05, and there was always a LOT of engine and frame heat, and add solar heat to it, always leaked. So .... you are not crazy. Sorry I do not have a fix for you. :blink:

In the old days we would just smack the side of the carb bowl with a hammer and all was well. Fuel injection though, just boggles the mind.......PM. <>< :blink:

I have noticed that if my tank is ~1/4-1/2 full and I have been riding that when I go to open the tank I get a huge phhhh and rush of air (that usually leaves a misting of gas on my hand as well). Is this normal? Seems the vent line would prevent this. As soon as I get some time I will clean it out but didnt want to spend the time if it was common. I dont seem to recall the '05 doing this last year but I bought it in September as well.

Check under your tank for hose routing and look for pinches in the vent lines.

Yamaha reworked the '06 FJR's fuel tank breather hose and overflow hose configuration just a bit. On the non-California '06 these two hoses are teed together into one hose just below the tank. So there should be one less hose at ground level under the bike. The California model was unchanged.

I doubt you'll see any fuel drips under a California model, at least not from a breather hose.

I have completely removed, cleaned, and reinstalled the hoses. No pinches when setting the tank back down either.

Well, I found that my vent hose, while not completely kinked was bent and stuck behind the stand in an awkward position...must have gotten stuck back there whent he dealer had the wheel, swingarm and all that off last week for service. Pulled it through and ran some compressed air through it and it's clear as a whistle. It will be in the 90's here this week so I'll find out soon enough if it worked or not.

I've read all the posts about this happening on hot days occasionally, but my bike does this everyday, even when its 60 degrees out. Hoses are cut at an angle facing rearward.
I've disconnected and cleaned both the Fuel overflow and vent hoses. Reconnect to tank, and clean entire paths from filler neck all the way down using contact cleaner. Everything is clear. Removed cap and performed the cleaning service detailed on this forum. My little orange grommet that completes the path between gap cap and filler neck to vent hose is in place.

Should I really be leaving puddles of fuel everyday from the vent hose? Puddles are still wet after a work day and are about 5" in diameter.

I've verified that it is coming from the vent hose and not the overflow hose. This is happening at full tank or 1/8 tank and everywhere in between.

I remember reading a post about drilling a hole in the fuel cap plate to allow venting to occur due to extremely stiff springs in the lid preventing normal operation and riders getting sprayed in the face upon opening the cap. This doesn't seem to be my issue I don't think.

Ideas? :blink:
