I thought I remember reading somewhere that someone makes meth resistant replacement seals for the factory washer tank, but I can't find that thread for the life of me. Does anyone know if these are available? Thanks!

Are you running 100% meth? Washer fluid has almost 75 percent meth in it depending what temp it's rated for I'm pretty sure.

I thought washer fluid was more like a 50/50 mix. Or was it 30/70?

Depends on the temperature it's rated to, -20 is like 39-50% methanol if I remember correctly.
I use windshield washer tank for 50/50 water meth on my charger, and it's been fine for ~4 years now.

I don't see anything for meth resistant grommets, but if you think about it, some of these cars are are 12 or so years old with 50/50 meth in the tank so stock replacement should last you 5 or 6 years. You could hog the tank out and use a bulkhead fitting made of brass or stainless but you'd have to figure out a pump solution, like a little inline jobby with 1/4 nipples maybe.

if you have to buy a new one, like i did, order for a base cts without the headlight washers- this way you have less holes
