Default '90 S2 fuel line question...

So I did some work to the car on sunday (valve cover gasket, new chain tensioner pads, new fuel lines) and I can't remember which fuel line went where.

I'm thinking the thicker hard line w/hose connects to the fuel rail while the smaller hard line w/hose is the return line and connects to the fpr? Did I get that right?

I haven't started the car yet as I ran out of time but is there a safe way to check if the connections are leaking before I actually start the car and it catches fire?

You're right on the fuel lines...the larger, front-most line (as comes out of the fender well) goes to the fuel rail. The smaller rear-most line goes from the fpr back to the fuel tank.

Thanks, I believe it's the same as on my '88 na as well.

How about testing the fuel system, any easy way to do it without starting the car? I was thinking of using the jumper lines on the dme relay but I'm not sure if that will work or not.
