Fuel Injectors: I "springed" a leak...Been a long winter., Leaky injectors only first day spring start up. Options

[orthobiz]

For two or three years now, two of my cars leak gasoline when taken out of winter hibernation and fired up. Run it long enough to realize it's leaking. Let stand overnight. Then, absolutely bone dry (couldn't resist that one).

I am told that this is not uncommon but did not find thread specifically mentioning this springtime phenomenon. Seems like "once a leak, always a leak." That has not been my experience.

Apparently exposure to gasoline causes the internal seals to swell and seal up? So far, the cars have been fine for the rest of our pitifully short Michigan driving season.

I am pretty sure it is from the injector itself, can't imagine bad hoses would seal themselves.

Is it possible NO ONE makes injectors for our cars???? 350 per new injector is steep and I wonder if shelf time is bad for the seals or whatever inside the injectors NOS. Like hard old rubber.

Extinguisher? Yes, on board, all the time, every car.

Am I driving a time bomb or have others experienced this?

Paul - It would be good to know exactly what was leaking. Was it the injector, the hose or either of the seals that seal the injector to the engine. The 2 injector seals are about a dollar each and the hoses are pretty inexpensive, compared to a new injector. Plus, all these rubber parts are easily replaced in 10-15 minutes.

I had been talking to Dave about a engine stumble problem on his 3.2 conversion. He did a lot of diagnosis to try to fix and then discovered it was just a kink in the fuel line. Sometimes the solution is easy.
