As greengt said, it might be over your head if youve never done em before. Find a friend to help you or something maybe.
Anyway though, you dont go through the trunk, you just follow the fuel line back from the engine and you'll see it. Spray the fitting with a lot of PB blaster and let it soak in for a bit cuz itll be nice and rusty and you risk breaking it.
