its your fuel pressure regulator. pain in the rear to change. its the small brass looking thing next to the throttle with a vacuum line going to it . the part cost me 50$ and i paid a guy $ 75 to put it in. worth every penny. looks easy to change yourself, but not as easy as it looks.

SOURCE: the smell i'm having is
if inded the smell of exhaust is getting into your car i would suggest not driving it until it is properly checked by a licensed meachanic. it could be entering through your heater/AC blower and in return be fatal if left untouched for a period of time

Was fuel smell present before you had fuel pump replaced? If yes I would sugest you drop tank and see if fuel vent hose is plugged forcing fuel back pressure line to vent through cap. If fuel smell was not present before you replaced fuel pump and seal. I would suggest you drop tank back out and check all fittings and hose conections. also if you still have old sending unit you could check to make sure they are exactly the same. As Sometimes you have to pull relief valve from old sending unit and install it in the new one, as some sending units wont have one in it. and some will have one that is regulated at a different fuel pressure. hope this helps Vic
