Default Alky Control Question

My Procharged C5 is equipped with an Alky Control meth system, and for a bunch of reasons, spends months sitting in my garage.For the second time in the past year, I got the "low washer fluid" warning, and the reservoir is close to empty. Since I haven't run the car often or hard enough to be using much meth, is it possible that it just evaporated, or should I suspect a leak?

Straight methanol will evaporate very quickly.

How long have you had the system? Ive needed to send my pump out about every 2 years for a rebuild due to 100% wearing the seals away.

You may have a leak at the tank seal. I havent had signifigant evaporation even parked in the hot FL sun.

I found the same thing on the car I bought that has an Alky Control kit on it.
I do think the pump needs a rebuild since I have seen some leakage below the pump but to tackle what I think is heavy evaporation, I just put a piece of double-layer saran wrap over the washer fill hole and closed the cap.
Been like that over the winter and the reservoir is still full, so it must have worked.

edit-to be clear, take the plastic wrap off the reservoir before driving the car.

How many months? If it was summer in a hot dry climate I might say evaporation....but winter time for a couple months no way...then I would be looking for a small slow leak.

Is it possible for the nozzle to be mounted below the tank, thus allowing for the meth. to be fed into the engine without the pump running?

There is supposed to be a check valve to stop it. I had a check valve go bad on my car. Possible you have the same problem.

To my recollection the installation instructions do say to mount the nozzles as high as possible to avoid siphoning or something to that effect.

The check valve is supposed to stop charge air from flowing back towards the meth pump, it doesn’t stop from from flowing out.

Yes it will, the spring will keep the valve shut unless pressure overcomes it... IIRC it's around 30psi check valve on most of these?

On my setup, I ran the check valve/nozzle to the ground and let it sit overnight, no drip or wetness. If OP is running one at all, it's possible it's gone bad

I stand corrected, just checked his website and it says it has a 10 psi cracking pressure.

10 psi, that does sound more reasonable. I was doing some math regarding what height of water would be required to crack a 30psi valve and it was some huge amount. We're getting a little off topic, but if I had my tank well above the nozzle I would definitely consider a solenoid in series or in place of the check valve.
