I had an interesting day yesterday with my 93. I took about a 300 mile trip and started smelling fuel towards the end of the trip. Well I pull into the hotel and look behind my left rear tire and fuel is leaking BAD onto the exhaust. Not good. So I jack it up and take off the wheel and discover the line had been resting on the exhaust and finally burnt through. I got out my service manual and discovered I could repair the nylon line with a coupling....... so I found a hole in the wall parts place that was actually REALLY helpful and he got me the correct 5\16 coupling that I needed.... COOL! Well I had no real source of HOT water at the hotel to make the lines workable so I used the coffee maker to heat some water and took the pot outside to the lot... well it worked OK but I still don't think the water was hot enough because I could not get the line to go ALL the way up on the barbs like I wanted. It went quite a ways though and seemed pretty stout so I went with it. The repair held fine on the return trip but I noticed going threw the mountains the car was PINGING BAD if I tried to maintain speed while climbing..... so I just went really slow and made it home ok but I need to find out what the hell went wrong besides the fuel leak.... When I filled up again I used premium and when I was finally close enough to home to not worry I romped on it a bit and listened and did'nt really hear anything but I am still worried! Anyone have any ideas? The car is a low milage 78k, well maintained STOCK vehicle. No check engine lights either.
