Remove the restrictor and re-test. Let me know the result. Also set the PI-R to Fully clockwise.

You can also increase the pump pressure (1/16" allen screw at front end of the pump head) to 180-190psi. (about 1/2 turn clockwise).

Re: How can tech me use hfs4-v2
 

So I can use 1.0 Check Valve Jet!

Use You said method?

If 1.0 Check Valve Jet on 180-190psi pump I can get how much cc?:)

Thanks

I would check the flow curve on the user manual. Take 15psi off for CVJ.
So.. what is the flow rate of the 1mm jet without the restrictor?

Re: How can tech me use hfs4-v2
 

I don't use restrictor

Re: How can tech me use hfs4-v2
 

Now or before? I read your first post on a 0.7mm restrictor.

Re: How can tech me use hfs4-v2
