Possible fuel leak!

[Nizmo]

I'm only getting about 21-22mpg, all highway. I smell fuel, pretty strong, only when I crack my windows. The smell seems to gather in the trunk, im hoping someone else has had these symptoms and knows a possible source.

There are all sorts of possible sources. Have you done any troubleshooting other than opening the window? Cycle the key on/off/on/off several times to run the fuel pump and pressurize the fuel system. Check all line connections starting at the tank (connections are on the left side of the tank hidden by a shield). My main line rusted enough to have fuel dripping at that connection. check the connections at the fuel filter (on passenger side firewall). Connections to the fuel rail, at injectors, at pressure regulator (left end of fuel rail). If nothing there, and the smell is really only at the rear, you may have to drop the tank.

I already fixed a leak at the throttle body, I replaced the fuel filter and pressure regulator. everything in the bay is good, and i have not seen any signs of leaks by the tank or running to the bay. Looks like im going to have to drop the tank thinking it might be some sort of seal on the tank w/ the pump hence the smell in the trunk.

Does it happen at any fuel level in the tank?

Could be leaking from the tank itself around the middle seam (between the top and bottom half of the tank). I had a similar problem and it was due to rust (it started within the seam and caused the upper and lower half of the tank to separate slightly). It would only leak/smell if I pumped more than half tank of gas though.

Thats probably it, cuz it smells the strongest after I top off the tank, once I get down to like half or below it seems to go away.
