Question
I have a 1994 s10 with a 2.2 engine. It appears that i have
a leak in the fuel inlet connector where it attaches to the
rail. Could you tell me what i would need to do to remove
the connector?
Thank You,
Robert

Answer
    I'm pretty sure that this is put together the same way the rest of the fuel system is, with a push-on snap connector using an O-ring seal.  You'll need to go to a parts store and get the special tool that is used to reach down inside the connector and push open the snap.  Once you've pulled the fitting out you'll see the O-ring.  You need to go to the dealer and get a new one.  You could try a parts store, but never be sure that they've sold you one that is fuel-proof.  Sometimes the plastic snap connector breaks when you're taking them apart, so get a new one of those if you can, as well.  One has to wonder why the O-ring failed, but it is fairly old and four-cylinder engines shake a lot, so it may not be that unusual.  Really a simple repair, just don't skip any parts, and make sure you depressurize the fuel system before pulling it apart.  The leak may do that for you, though.
