AEM in tank fuel pump, HELP !!

[C_Henry]

I've got a AEM  intank fuel pump in a 05 Busa . It starts and runs for about 5 min , but then dies unless I rev the motor . 
I couldn't get the plastic piece up under the rubber grommet on the fuel pump . Is this it ? If so , how do I make it fit ?  Thanks !

Try running it with the fuel cap loose

Will do !

Yes !!! It keeps running with the cap open Sportbikeryder . Whats that mean , vapor locking ?

you have a vent plugged on the tank

Thanks !

Yup. The tank needs to get some air put back into it to replace the fuel that went to the engine, or it will create a vacuum in the tank. Should be a vent in the cap area,
