We've got an 8070 that is leaking fuel.  The best we can tell is the leak is coming from the tee that comes out the back side of the pump.  I think it is a return line.  How can this leak be stopped?  Is it an o-ring or threaded?  Is there something that can be put on the threads if it is threaded?  Thanks in adavance!

that TEE is for the return, and it does seal with an o-ring.
