For the past week, I have been contemplating what to do about a pesky problem. The Corvair had developed a persistent fuel leak where the sending unit attaches to the tank. One repair shop told me it was wet there and at the metal fuel line which runs through the heat exchanger. With no guesstimate as to how long it would take to fix the leak, I decided to figure things out myself. Am I ever glad that I did!
Today, I drove the car up on my personal car ramps and took a look for myself. All along I was thinking that the leak was coming from the sending unit gasket. But it wasn’t; it was something very simple. When I crawled under the car, I noticed that the leak was coming from a hose clamp near the sending unit. On my car, a rubber(?) hose connects the sending unit to the steel fuel line to the engine. All I did was tighten the hose clamp and the drip disappeared. That’s all it took!
P.S. Do you know what dripping gasoline does to an asphalt driveway? Yikes!
