Fuel o-ring or not?

I was wondering if anyone knows if there was an o-ring on the fuel inlet hose? I put the entire engine back together, and found a huge leak there. I know it was hard to get out when I took it out, but there was no o-ring on the tube, and I don't remember seeing one in the fuel rail.

If there is/was, this would solve my headache. I have found the leak to be exactly from the inlet, if sprays out the top once it is tightened down, as if there is a looseness to it. I can also wiggle the tube in and out even when tightened all the way.

Thanks

I found out, from reading another thread, that there is indeed an o-ring. Be very careful when removing the fuel inlet line, don't lose this o-ring! I had to buy a fuel resistive o-ring kit from CSK (partsmaerica.com) and find one that fit. Now it is all back together!! Yeah.... Just a few more things to get fixed!
