fuel filler neck replacement

My 02 3.4L has had check engine light on for awhile and its due for inspection. It seems to be my evap system and I had a smoke test done and the mechanic said it was leaking from the filler neck. I was wondering if this is an easy part to replace as I called the dealer and the part is only $130. Need to get truck inspected fast its way over due and this is the only thing keeping it from passing. any input on the topic would be appreciated

 

Would this work?

Keep the receipt if it doesn't work bring it back.
Or if it does work and you don't need it anymore bring it back.
