Fuel line Stolen, need to find replacement fuel lines?

I'll make it simple; my fuel line was stolen off my vehicle. I've been trying to find a replacement for the one line but to no avail. The line I'm looking for is the one attached to the fuel filter. I've taken pictures of the missing line location. I put a rag in the filter to "stop the bleeding". The line missing is the one going to the engine. Not the one going to the tank. I've seen one on Lines to Go, but they only sell all three together. I really just want to find out is there a part number for this line. Is there a different GM line I can use for this (maybe off another 3800 engine), and where do I look under the car to see where they detached the line from? I see the fuel filter, and i can see the lines coming from the engine. I don't know where they attach though. I don't see any pictures online that show this. Any help would be appreciated. Thank you in advance and happy New Year to all.
