Last night I found out that my FPSS is faulty, again.
I,v had at least three go bad on me. They either start leaking or simply don't work.
Is there a particular brand or other solution you guys can recommend?
I have a trackday coming up on monday and am going to have to run without a FPSS, which makes me kind of nervous.

are you sure they are faulty and not just out of adjustment??? kinda strange to have 3 go bad on you. i would start by checkin the adjustment on it. goodluck.

The current problem I am having is that my solenoids click like crazy. It sort of sounds like a machine gun. click-click-click in rapid succession even when the system is off.
With the FPSS out of the loop everything seems to be fine.
Thank you for your help.

sounds like an adjustment to me-
if it is running borderline to your fuel pressure, slight fluctuations could make it cycle-
i would think a slight adjustment and you would be good-
but then i dont run one so take my advice w/ a grain of salt

^ what he said. i would make a slight adjustment and run it. see what happens.. if its on the borderline it'll cause a problem like your having. goodluck...keep us updated when you pin point!!

I do run the NX FPSS.
I will try to adjust it after Monday.
But if it is an adjustment issue, why would the solenoids act erraticly when the car is not even on??

Yes the relay di get wet, but even after I replaced it, the same problem persisted.
Thanks for all your help guys.
Which is the most reputable FPSS?

After you shut the car off fuel pressure is still in the lines.

Sounds like an adjustment thing to me too. Keep us informed.
