Hey guys! when i bought my r32 gtst with rb25de it never had a charcoal canister, the vent line was simply capped off and i also noticed when you unscrew the fuel cap it never whiffed out air like its meant to and i always had a pretty strong fuel fume smell while driving no matter what windows up/windows down didn't seem to matter.. after a while i thought i would plumb it back in, bought the canister hooked it up correctly and tested it out over the next few weeks, the smell seemed to have gone but then when the windows where down it was stronger then ever... about a year ago i replaced the fuel pump with a walbro and replaced the fuel lines from the tank to the hard lines and when i got the car i replaced from the hard lines to the filter and then to the rail.. but it still smelt so i did some more research and found that they have a common leak area with in the compliance fuel restrictor, i pulled that out and found that the sealant they had used had perished, i re-sealed it with sickaflex and it still smelt.. so now bassicly I'm after advice on what steps to take next.. a lot of people have said to replace the o ring above the fuel pump but I'm almost certain that is sealed correctly as you can't smell anything in the boot... the only thing i can think of it being is the filler neck itself or the vent lines from the tank... I'm pretty much at the stage that i want to drop the tank and replace everything... if anyone has any advice or ideas please let me know and thank you in advance!
