Has anyone with a water meth system seen rust form in their lines? I have stainless steel lines and rust is forming on the AN connections. This rust eventually clogged up the nozzle. I thought stainless steel is corrosion resistant.
Maybe the line itself is stainless but the connector is not? I'm just guessing here though.
There's likely either some carbon steel in your system or the stainless is an inferior grade.
I have an AIS trunk mount kit that I run 100% VP M1/M5 methanol and i've never seen rust in the lines. It has siezed up a check valve before and I believe thats from running 100% meth.
Keep in mind that pulling the nozzles and cleaning the screens should go hand in hand with oil changes.
