I've got a 2000 Corolla with a leaking, corroded fuel line(s)? My gas mileage on local driving has gone down to half what it had been, while on long highway speed drives, it is only down by about ten percent. When I brought the car to my local garage for the annual state inspection, I passed the safety part but was told that the pollution emissions test could not be made until I got the "Check Engine" light to go out, and that a Toyota dealer would be needed to do that. I then brought the car to a metropolitan mega-dealership, where I was told that the fuel lines were leaking and that it would cost me $2,030 to have them replace them, but even if I had them do that, there was no guarantee that the car would pass the emissions test, just that it could then be tested. They were also "nice" enough to provide me with a list of other things they had found wrong with my car, and while they didn't price their repair cost, it would easily be another two thousand dollars. The price of the fuel line replacement/repair broke down into $1,850 for parts and $180 for labor, and so I wouldn't be saving much of anything if I bought the parts from them and did the installation myself. I have also been told that there are no aftermarket Toyota stainless steel fuel lines available and that making my own would surely entail more work than it was worth. There is absolutely positively no way that I am going to pay $2,000 to repair a car that will only be worth $2,000 after the repair is completed. What would like to know is" 1) If I determine that only one of the lines is leaking, should I be able to get a dealer to replace just that one line? 2) If they won't do it, will Toyota sell me just one line, rather than a complete set? 3) If I replace the leaking line or lines myself, will I still need to have a dealer do something to reset the Check Engine light circuit, or will the light simply not come on if I restart the repaired vehicle with no fuel leakage taking place, and most importantly, 4) Is there any cheapskate, inferior repair I can do, like replacing a leaking section with a repair piece, or perhaps concocting some kind of epoxy-filled tubular encasement perhaps either using a fiberglass wrap or even a copper or plated steel wrap that I would solder closed to give backing strength to the epoxy? And finally, to aid me in my own inspection, can anyone direct me to an on-line drawing of the fuel lines? I am a "carburetor age" guy who only knows the whereabouts of the line that goes from an engine's external fuel pump, to the fuel filter (on Ford's, we used to punch a hole through them when they got clogged), and then into the carburetor.
