Surge arrestor for Alkycontrol?

[Pronto]

When testing the Alkycontrol systems on our cars, I've noticed how much pulsating the Shurflo vane pump has. While looking around I came across this system- Element Hydramist http://www.elementtuning.com/Hydramist/hydramistguide.htm . It has a 22 cc surge arrestor attached to the output which smooths out the pulses to the spray nozzles. Has anyone tried something like this? I would think there would be some benefit from having a steady stream rather that the pulses especially at higher pump speeds. I tried emailing them to see if the arrestor was available separately but they said it was discontinued. I tried searching with no luck for something like that in the picture. Found copper ones for water hammer but I don't think they would be safe with meth. Radiam makes a fuel pulsator for fuel lines but they are not rated for the 180 psi of the Shurflo pump http://www.radiumauto.com/Fuel-Pulse-Damper-In-line-Kits-P751.aspx . Any ideas on where to find something like the one used by the Element kit?

the shurflo is a diaphragm ( three valves ), not a vane pump

Ok, I thought it was a vane. Either way is does pulsate quite a bit.

It was my understanding that's how those type of pumps work.

Anything that can be done to reduce fuel pulsations is helpful. Even more so on the injector fuel rail side.

As for alky, reducing fuel flow fluctuations help with retaining a steady AFR and cylinder temperature/pressure across all cylinders. To do some scientific research, check the rate of oscillation at various pump speeds. Then match it up with the engine rate of induction.

May find that a pulsation damper could be helpful, or that it doesn't matter.

I just thought it would be an easy mod that could enhance the system and wouldn't hurt anything. The kits I found that have a surge arrestor were from about 2008 and the newest versions of that kit don't have that arrestor.
