As I was installing my ZEX wet kit I removed the valve from the shrader on the fuel rail, the car was off for maybe an hour before I did this....well anywho when i removed the valve, there was no pressure at all, not a drop came out...I remember vaguely about something supposed to keep the lines pressurized while the car is off, so that the next start will not take as long....or maybe Im wrong....ARGh

Anyone know? is this a prob or am I just imagining things?

Yes. It means your car is not compatible with ZEX. Might as well go ahead and send the kit to me.

Back when I had my engine in (grr) mine didn't hold long either. I could watch the scheader valve pressure drop right after cranking

I have not read up on this, but I would say that it does not hold pressure because it has a return line. If the fuel pump stays on all the time then the pressure release would open and let the fuel go through the return line. I don't know just my thoughts.

It should hold pressure for a least an hour or more- possible causes for not doing it- leaky injector or faulty check valve in the fuel pump

Ok, hmmm....

Can I install an Inline fuel pump without removing the stock pump?? If so where does it mount?
