    A/C and outside of car smelling like gas / varnish

    So i was driving today with the a/c on and i started getting this weird smell kinda like gas or varnish. i got home parked in the garage and a few minutes later the whole garage had the same weird smell.
    It doesn't smell like gas out of the pump but its strong and smells horrible.
    I was doing some reading on the forum about a FPR that could go bad and cause a hard start when its warm which i had today and could cause a gas smell. Is this my problem or is it something else? All help is very appreciated.

    ----------

    Just to add to the post its a 1993 sedan deville with no codes

    can't tell from here -

    but - you could pull the vacuum supply hose off the FPR -
    and check if there is ANY gas in the hose -

    It's a small metal canister on the fuel rail.

    You can just barely see it in the lower right of this picture next to the TB.

    Thank you ranger, i pulled the hose off and there was no fuel leaking from it and when i had the engine running it whistled pretty good before i put the hose back on so im gonna rule that out as the problem.
    i didnt have the smell right now either so i think its a intermittent problem, is it possibly the evap canister?

    EVAP system is a possibility.

    Several codes associated with EVAP - an emissions (carefully monitored) system.

    Did you check the hose, or the nipple on the FPR?

    Look at it. Put your finger on it. If it doesn't look or feel wet, it's OK.
