Well it's been a year since I installed new injectors (factory) and pulled the intake off and refurbed. I installed new cold start injector, new fuel line, factory clamps, etc. Everything has been perking right along until yesterday. As I was backing out I found a dinner plate size puddle of raw fuel on concrete. I was in a hurry so I changed cars and last night tried to find the leak. Everything was dry. Tried it again this morning and everything is dry. I especially felt around the CS injector but inspected everything. No leak.

Any suggestions?
