2005 challanger 180 fuel pump/system question problem

[kram925]

I recently purchased a 2005 challanger 215 scic i was cleaning it up after my first day out and i noticed with the key off about every 15 seconds i could here the fuel pump kick on for aprox 3 sec. i will continously do it until the battery dies or you turn off the battery switch or pull the fuse. I called the dealer and they informed me there is no relay.So now i am at a loss for what to check or how. When boat is running everything seems to run fine...Could use some help with this one...any info would be appreciated....
