putting a gauge on different hoses will not show anything they will both read the same.You need to measure the flow rate do that by taking quick connect off the end of the two hoses and pump water from your machine into a large jug or bucket. Time how long it takes to fill to a certain level with each hose. This will show differences in flow rate!Cheers Goron
Smaller bore = higher pressure.John
Can anyone tell me what the bore diameter of a solution hose should be? Also, where can I order a custom length?Many thanks
