I just solved my fuel smell problem after spending $80 on the seals from the dealer. Even after changing the seals, which was really easy. The smell of gas would fill the cabin of the car,even with the vents closed.
I traced the smell to the trunk after getting a strong odor in the trunk area.I was about to open up the fuel pump area. But my nose was leading me to the fuel filler door. Longer story shortened, it was my locking gas cap venting the vapors into the trunk,which then entered the cabin.$8 for a regular fuel cap and problems fixed.
Before you go big, check the simple things first. Doing the injectors made me find some smaller issues.
1. Missing locking clip on one injector, causing intermittent shaking while at idle. Fixed thanks to a G1 at the U pull it.
2. One damaged seal on one injecter.all four parts on all injecter replaced.
3. One injecter missing the filter on top. Thank god the G1 carries the same exact filter. the injecters look the same but there's a small difference in the G1 injecter.
