Petrol Cap Pipes

Post by harry37 » Sat Nov 11, 2017 11:00 am



Hello to All,

I usually find everything I need from this forum but I am at a loss this time.

I have a 98 GL1500se Trike and I'm preparing for winter maintenance. I have just noticed that the pink pipe from the petrol cap going under the seat area then splits off in two but neither of these are connected to anything. I presume one is a simple breather but the other where should that go? Or is it because I have trike so some sort of ancillary is no longer used.

I have had a look in the manual but I cant find anything and I have searched this forum with no luck. Any information relating to this is really appreciated.

Kindest regards

Harry

Are you asking the T shape plastic piece?

If so, there should be a hose connected to the lower end and nothing connected to the side end of the T piece, as shown below.

Thank you very much. It is the plastic T Piece, it just appeared to be very odd having nothing connected to what is clearly one open end of the T Piece.

Really appreciated

Kindest Regards

There is a hook on the clutch cover near the clutch bleeder, it should be inserted there. #3 in the picture.

It is a free piece, just a breather, drain hose.
The open end of T functions as a syphon breaker, to prevent fuel leak, if the bike is dropped.

On California bikes, it goes to an evaporative canister to capture the noxious fumes and prevent them from irritating the delicate Californian lungs. For the rest of the world, it's connected to nothing, to spew those fumes into the atmosphere. :)

I live in England but my bike which is now converted to a trike is a California model so I think it would have had the canister. However, like I said I live in England and our fresh air is pretty much like our weather dark and murky at times but riding my trike makes up for it.

Cheers
