I have recently purchased a magnetic fuel saver that attached to the incoming fuel line. What it does is separates fuel particles so oxygen reaches all parts. Supposedly I will get about 5 MPG more on the highway. I have located the fuel lines. The only problem is that there are two fuel lines. I own a 1999 Saturn SL1. Can someone please tell me which fuel line is incoming? I know they are to the right of the engine, when looking at it from the front with the hood open, so a simple "closest to the engine/farthest from the engine" answer will suffice. After I come back from New York I will post my before/after fuel economy comparison. If it works I highly recommend this product to others. I only got it for on eBay, so it won't be much of a loss if it doesnt. Worth a try, though. Thanks in advance! -Joey
