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?

I have been having the same issue on one of my 914s where one of the injector bodys (and sometimes the pump body) will leak a little when first pressurized in the spring but then goes away and is fine the rest of the season. Always makes me super nervous when i see it, but that is why i always bring my halon bottle with me.

As for replacements, I have not personally tried these yet but I noticed them when hunting for some injectors for a new Megasquirt project I am working on..

Not sure what the difference is on those two parts, but they are listed as NEW replacements for 2.0 D-jet cars. they appear to have l-jet rather than d-jet connectors however I believe d-jet connectors will still fit, though just upgrading your harness connectors to l-jet style would probably be an improvement. I have a set of what appears to be these injectors that came with a rebuilt 2.0 motor i picked up. I havent fired it up yet, debating if I give them a shot or replace them with an OEM set. Ive considered sending them out along side an OEM set to get them flow benched and compared. If anyone has that data I would love to see it.
