Gentleman,
The timing for this thread is ironic, as I'm in the middle of this very same job on my car.
No matter what I did, I haven't been been able to get it to idle smoothly.
I decided to replace the pressure valve seals and came across some rust corrosion on the internals and the valve assembly - that which is fuel soaked even.
I have only taken apart number 1 so far and am about to do the remaining ones.
Has anyone else ever experienced this? and is it normal to a certain extent? Also, what about replacing the springs - do they wear like injector springs or valve springs? also, why is the valve holder hold down holes that screw into the pump shaped in a manner that would leave the potential for misalignment possible, as if there is intended to be some sort of adjustment?
Thansk in advance,
Adam Bush
