I just finished installing my new 385 Stroker and when I turn the key I'm getting fuel coming out on one of the connections under the drivers door. Is there only the plastic retainer clip on these?, or am I missing someting else like an o-ring. They are fairly new lines off my old car and I have a couple new clips I've used and yes I know they are 2 different sizes 5/16 & 3/8. Thanks for any help
