Am I missing something?!

[Skippernick]

I have just performed a coolant change and something under the tank got me confused.
I have 3 fitting ones with the isolation valve and 2 others which have a pipe loop between them over the rubber drip catcher?
I don't think this is right but as i have never had a problem fuel wise i am confused. The tank gurgles quite a bit though!
Some one explain to me if this is right.

[darrsi]

3 fitting ones what?
You've lost me?

[Disorderlypunk]

i have been looking at this myself - i think it could be a overflow outlet maybe - i dont have a link pipe on mine though they are just open

[darrsi]

Are you on about the two little pipes under the fuel tank?


If so one is an air breather that goes through the tank up to the cap, the other is an overflow pipe for fuel, or any rain that may pass the outer cap. The hole is on the left side for when the bike's on the sidestand.

[darrsi]

If they're both looped then your tank isn't breathing properly at all, whatever is looping them needs removing.

Sorry tried to upload a pic but it was to big.
On the underside of the tank there are 3 fittings. One supplies the fuel to the carbs, the other 2 are right next to each other with a piece of rubber pipe joining the 2 fittings together. They are located on the right side of the tank facing forward above a rubber funnel for want of a better description.

Yeah, vent and overspill.
Shouldn't be joined at all.
On 98/99 bikes they have pipes coming off them going down towards the floor, then the funnel was used instead to make things a bit neater i s'pose.

[Skippernick]

so i should just remove it, no need for the pipe on either.
I wonder if i put it on there when i removed the tank a couple of years ago, to prevent spillage.

Yeah they should be open.
Be careful one side isn't full of fuel from overflow.

cheers buddy,
bet my tank won't gurgle any more now as well.

I suppose you could call one a fuel overflow, but it's really there to drain rainwater away from the filler cap area.
It's just as well yours never sees rain, though you could have introduced water to the tank when you wash the bike.
It'd be interesting to see what comes out when you take the link hose off.

interesting thought - if the 'funnel' catches what falls from that then where did the funnel pipe lead too - wasnt it into the airbox ??
just went to pods so i ripped everything out and threw it under a workbench
water into airbox wouldnt be a good thing

Funnel pushes onto a drainage pipe that goes straight down towards the floor.

this is still needing breather pipe leading almost  out the bottom of the bike. i know this cos i didnt re attach mine and got told it affects the performance.
or is that the over flow leaking into the air box as Disorderly punk says; i still havent done mine

The necessity of the drainage pipe is simply because it is located to the right side of the bike if i remember correctly, which safely aims excess fuel away from the direct path of the rear tyre.

Well took the pipe off this evening, and about 10cc of runny white liquid came out!!!!
The tank stopped gurgling straight away as well

We all love our Fazers, but most don't take it quite that far.

   Bike lit a snout up afterwards.
