That is good to know, thank you

Richard suggests threading a fine thread allen screw into the feed hose going to the gauge. There will be enough flow past the threads to register pressure but it will damp most of the surge.
Yes, I read that and have already 5mm allen screw, but to make sure I took a wide range pressure so it should take all that beating, I am also going to change my hose which came with the set, it is black but I want a see through hose so I can see if there is air bubbles in the line.

If you have an accumulator in the system you can't do it that way becasue of the time delay to pressureize the accumulator.

If you are running an accumulator you usually have a solenoid to trigger the spray (as you show in your diagram). If you place that near the jets it does not matter how long the fluid path is as the fluid line will be pressurized all the time. That is the way I had mine set up. The solenoid was only inches from the jet, and the accumulator was between the solenoid and the pump with the line at full pressure all the time the car was running.
Indeed I am going to use on demand function at the pump and the line will be constantly under pressure, when I turn the key on the pump will bring the system on pressure, the distance between the accumulator from trunk to first solenoid will be 4meter (160 inch) and than it will split in two directly after the solenoid after that both lines go to another solenoids just before the nozzles.

Thanks for the heads up Larry.
