Greetings, eh?

I pulled into Calgary coming from Edmonton on Friday night and the car started to shudder. When I stopped and popped the hood, injector #4 was spitting fuel out the top. I loosened and re-tightened the line while the engine was hot, but it didn't help. I'm now back in Edmonton *without* my car (having parked it safely in Calgary) and I'm planning a trip back down this weekend to fix it.

The trouble is, I want to get all of the parts I need in order so I don't have to do this trip twice.

I've seen a few threads on this forum that recommend replacing the injector line only, so I plan on buying one of those:

Injector line Flares leak at injector-any fix for this?

I've seen some mention of replacing the braided injector return lines too (I had no idea those were for return - man, I love the info I get from this forum). Since those lines aren't showing a leak, I don't think I want to touch them, but I'll bring some braided line just in case.

Should I buy an injector as well, just in case? Is there *any* reason to suspect that a leaky injector line would be caused by a fouled injector? I don't want to spend money on extra parts if I can help it - especially if I can't return them.

Thanks, everyone. I'll try to remember to let you know how it goes.
