    I have a blazer gas tank that is fuel injected and it is leaking from the top. It is where the fuel pump and sender and everything go in, its leaking from the locking ring. Any suggestions, want to be armed with some knowledge before I try to fix it.

    There is a big O-ring under the sender/pick-up unit. Not sure if they can be bought in your local parts store but i would check with them first.

    IIRC you can get the new o-ring seal when you bye a sock and a fuel pump... i believe it was 40 bones or so.. not bad, because if your gunna drop the tank you might as well change the pump and sock while you are at it

    I checked at our parts store and found out the O-ring you need is a dealer itiem and does not come with a fuel pump or sock.

    The Delco pump I purchased came with a sock and the o-ring, FWIW.

    Might check acdelco.com and see if they list what comes with your particular pump.

    Also, if you have a local place that sells o-rings, (more an industrial supplier, not a hardware store) they MIGHT have what you need.

    I bought a new tank, got a free o-ring. Bought a new pump, got a free o-ring, bought a new sock, and thought "I better get a new o-ring" before opening the others and got a new o-ring. Now I have 2-spares!
