I bought this filter to help keep contaminants out of the nozzle.
It says to install it on the low pressure side of the pump (between the tank and the pump) but if you do that then water/meth comes pouring out by gravity any time I go to change the filter.
My tank is above my pump. After my pump (on the high pressure side) I have a solenoid that stops the meth from gravity flowing to the engine.
Any ideas? A shut off valve seems kind of hokey but?
