1. Is the system primed up to pressure?

If by this you mean is the pump primed, then yes. Prior to hooking the pump flow outlet -> WPS #162/201, I fired the aux. trunk pump and pushed fluid all the way to the WPS #162/201. The pump itself then fired and stopped - I assumed it built pressure.

2. Have to disconnected one of the wire of the manifold pressure switch before grounding the green wire?

No, this was not mentioned before, or if so, I missed it. The only wire I ground was the green injector wire. I assume you'd like me to also pull off either the blue wire or ground wire from the PS #157?

With the blue wire off, the system should trigger. Please let me know.

It seems to spray instantly when turned on now so the intake line is no longer dry. The issue of getting it to shutoff is still a problem though. Why is the clogged jet warning light coming on if it is spraying? I have disconnected the jet to make sure it is actually spraying.

To prime the pump with a syringe do I need to remove the intake line and squirt water into the pump? I'm sure I'll need to do this in the future as I don't have a low windshield wiper fluid sensor.

Bingo. That did it, and the rebuilt pump works great too. Terrific service, it is greatly appreciated.

Thanks, Richard.

They set the low and high points of the flow window. Without them adjusted properly the system will not be able to detect a leak or clogged jet. I don't remember off the top of my head exactly where to put them, but basically the sc should be to 6 bars at full flow, wl should be to 4-5, and wh should be at 7-8.

Here's another pretty picture:



I think we've ordered 5 HFS-6 systems so far. So hurry it up with getting them to us please

Default Question for Richard

Richard, what could cause the water injection light and clogged warning light to come on when the ignition key is turned to on? It sprays fine, albeit constantly. Breaking contact between the blue and black wires does not turn it off.

The clog led will stay on for about50-10second at start up. It is normal. If all is well, it will turn off.

It stays on and never turns off. It also sprays immediately when turned on and will not stop.

Richard,

Well, I thought I had it licked, but apparently not. I ran the car today and the system worked perfectly. I had to park the car for a couple of hours, and on re-start both pumps fired continuously and I got a LED warning light. I popped everything open, the lines were all good, no leaks, no visible shorts or wiring problems; then I re-ground both the injector wire and popped off the blue wire again on the 806-157, and the injector fired perfectly, but the pumps will not turn off no matter what I do. Could there be an issue with the pressure switch, or do you have some other ideas. I'm stumped.

The pressure switch (806-162) is responsible for shutting off the pump when the set pressure is reached. A mechanical switch is prone to wear and loose adjustment, this is caused by vubration and temperatre cycles inside the enigne bay.

I would concentrate the work on this switch, reset it to 7 bar and seal the adjust screw with some sealant. Fist of all, try a 1/$ turn counter-clockwise and see if it made any difference.

Aonther possible cause is the center pin of the pump is not making good contact with the 806-162. Unplug the 3-pin connector and check for any sign of corrosion.

Hi my questions is what do I need to run to have the failsafe on? and if I have an AEM EMS and Electronic valve control (perrin) I don't need any other kind of controller to control my boost right? I can just controller with my laptop to the Aem ECU that is right?

Ricahrd:

I sent you an email rather than take up more space here; however, I'll post back here to let others know what we did and how to fix this pressure switch problem.

Default PWI-1 Flow volume issue

Hey Richard,
My tuner may have been in touch with you on this already, but I have done some more testing.
It was regarding a new Perrin PWI-1 system that I installed and have been trying to get 100 percent functional in my wrx prior to tuning.

Some details
• The flow sensor has a part# 806-428 and a serial# 3323
• Tank in hatch area,
• Primer pump after tank
• Filter between tank and primer pump has been cleaned/inspected.
On control unit: During 100% test cycle
• Pots adjusted to flickering orange (middle pot) and flickering blue (last pot)
• The third pot (Blue) needs to be turned nearly fully clockwise to maintain a blue flicker during test and to keep the low flow light out on the remote control/display.
On main pump assembly:
• The flow sensor has been taken apart and both screens cleaned (2x) to be sure.
• No kinks in the feed lines.
At nozzle outlet:
• Low flow volume measured at nozzle via multiple tests with different nozzles. Both pumps running (sound normal)
• Using a 1mm nozzle, I get an average of 240ml of spray volume/min.
• Using .8mm nozzle, I get an average of 210ml of spray volume/min

What else can I test? or What could the problem be??

Richard, I sent you an email last week about the pressure switch (806-162) - did you get it?

Where can I order the jet adapter? I looked on the Underdog Racing website and couldn't seem to find it.

Thanks.

I might have some laying around.

So.... weren't those HFS-6s supposed to be out by now?

I got the message, thank you.

I gather you have fixed it by giving the switch internal a good clean. Just require resetting the system pressure again. Requires an inline pressure switch:

http://www.mcmaster.com/#pressure-gauges/=1npgkb about $10.00

You may want to damp it with something on the inlet or it will shake the guage to bits.

Thanks, Richard. Buying the guage and resetting the pressure back to 7 bar will be easy enough, but the devil is always in the details: namely, how do I couple the Aquamist jet M8 male end to the 1/8" NPT male guage end (or snubber end to control the pulsation)? Or is there an easier way to do the same thing without trying to track down an exotic coupler that I'm only going to use one time?
