If the valve is

I basically just had the nozzles spraying in a bucket so when it emptied the washer res I just refilled it with the bucket

I plan on upgrading all the exhaust valves to the LY6 valves, which are factory inconel. About half the price of ferra valves and dont have a 2-3 week wait time.

With that said, 1 and 2 14gph nozzles empty the tank and fill up a bucket fast!

The goal in this is to see if the pump can support 3 14gph nozzles without dropping pressure.

I cant remember but at what pressure does the Alky control kit turn the LED green? I am curious if it will support three 14gph nozzles.
