Rear fuel tank nuts

My bike is a 2018 dragster

I’m reinstalling the tank but there are these two nuts within a little bracket that fell onto the rear undertray.

I retrieved the two nuts but I’m having a hard time putting where they go.

Do they face downwards like the first photo are upwards like the second photo.

Anyone with a dragster know the orientation of these nuts that connect the rear of the gas tank to the frame ?

Using the B3 Workshop manual it appears the hose on the right goes to the Evaporative Emissions System....if you are a US bike.

Thank you very much! Last night I had some gas leaking from the right fuel tank nipple which had me believing that it’s the fuel overflow and the left nipple is the evaporative emissions hose.

If you have fuel leaking from that right nipple, you have a tank issue.

Think about how the bike sits on the side stand and the nipple arrangement makes sense.

I'll say it again: You have a fuel tank internal issue. It should not leak from that right side nipple as that would indicate raw fuel going into your charcoal canister. Fuelion that canister will cause poor running as it affects air flow into the engine.

The drain lines and vent lines are molded into the tank shell. (Look inside and you will see no lines.) Leakage indicates ethanol damage and is covered under warranty.

Having a full fuel tank...unless SEVERELY overfilled, should not cause fuel to go down that evap line.

If your tank is filled to the brim..... up into the fill tube under the cap...expanding fuel from heat will force raw fuel through the vent and down the hose to the evap can.

Never fill your tank up into the fill tube.
