quick fuel flange enquiry

People,

I am just refitting a fuel flange to my tank.

Inside the tank there are two overflow tubes that connect to the flange assemlby.

Can someone please advise which of the tubes goes to which of the connections on the flange???

They appear to both go through the flange and then are not connected to anything. Can someone please help as the manual suggests they are simply overflows from the filler cap

Cheers

One is water drain from cap area, the other is the gas cap vent. They are connected together with a "Y" fitting and led to below the bike near the side stand....

Except for USA bikes with emissions canisters. The gas cap vent goes to the canister if external. On internal canister bikes the vent hose goes to a 4 way juncture and feeds into the intake manifold spigots.

I used to be fast....now I just dream about it.

Submariner;
there is a diagram on page E-03 of the parts book showing that they 'T' together below the tank.....therefore it doesn't matter with version #1

BUT listen to Ed....i have an internal cannister on my '05 and it does not, so i guess i have version #1 of cannister plumbing

Ed is describing version #2 where the vent from the cannister MUST connected to the 4 vacuum lines

Lee's Tambo was different was a 3rd version

if you make these lines ~30cm longer, then you won't have to disconnect them to change fuel filters

Guys, thanks for your help but I am finding it confusing!!!! I have a F4 750 2000 model which has an internal fuel canister. The tank is now on the bike which I have had running up to 95 degrees centigrade with no problems.

I believe looking at the diagram I have probably connected them incorrectly as I did not have the two pipes crossing as in the diagram.

Under the tank they definately both fit into the t shaped piece which definately drians to the floor

I don't think you have an evap system on your bike. If they "T" together under the tank and drain to ground then it doesn't matter which is on which spigot inside the tank....they are both going the same place in the end.

Ride on!!!!
