Is a 1qt can enough?
 

Do you guys think a 1qt can is large enough for a 2d system with the washer primer pump, and two 1mm jets? This is on a car that is only driven on weekends and will turn on at 10psi.

I run 1 1mm jet and a 4l water resovior, if driving it "properly" the water will run out the same time as the fuel in the tank, I think a 1 quart resovior would run out very quickly indeed with two 1mm jets..

Thanks for the tip. I actually was just able to locate a larger container. It's almost a gallon now.

Depends on how long you will be running. I use a 5L tank in my car. I drive on the autobahn almost daily in Germany and WOT driving is normal, even in 5th gear at 160 MPH, so I need more water. The tank lasts me about 2 weeks before I need to refill it with a 150 psi pump and stage 1 deluxe coolingmist injector. No problems at all and the system is vitually maintenance free due to the in line pre-pump filter. I only use distilled water and pure methanol though. Some people use windshield washer, blue, fluid. I don't know how often this clogs injectors, but I think over time that setup would be more of a headache due to the solvents and or soapy solution they use to clean windshields. Not sure, but just seems to be my opinion anyway.
