Correct: the greater the distance the regulator is out the higher the pressure so the gasket would act minimally in the manner a ship does IF it keeps the regulator out of the dist further.
djenka018 is correct.
However- if you're just hoping to find the gasket I have a regulator out and can measure the gasket with a micrometer.
Note: the working condition of the spring is essential! On most of these cars it could stand to be replaced!
Thanks for the feedback the o-ring was in fact fuel wet, and without the spring installed it went in easily.
Problem is actually knowing if the force you are feeling is being exerted by the spring or the o-ring not wanting to get in.
So if I get this right the correct procedure should be:
1- Oil the o-ring a bit.
2- Press the whole unit until it feels like the o-ring has slipped in and the thread has made contact.
3- Should be able to easily screw by hand?
4- Torque
Another question that comes to mind, how come only changing 1 o-ring will mess up the tolerances so much as to vary the system pressure if I'm not messing with the shims?

It shouldn't but the pressure regulator is stupid sensitive. You may want to consider replacing the whole regulator with the rebuild Bosch kit since you wanted to see the shims so badly ?
