Default Re: HFS-6 Inconcistent Injection

Looks very clean to me. Good.

What are the flow results of a 1mm nozzle for 1 minute?

Looks clean from the outside. I wonder how clean is the internals, FAV and flow sensor. Do you use distilled water?

One more possibility for inconsistency. Since the pump is not water proofed. The internal bearing may be partially seized and cannot generate a proper pressure. Can you remove the pump head and check the pump bearings.

Alternatively, splice in an inline 300psi pressure gauge, and check if the line pressure is around 160psi.
