We've changed the fuel pump, pressure regulator, gas cap, and had a tune up and the pressure is still building...What else can it be?
The fuel pump surging at first could be caused by the fuel pressure bleeding off and the pump has to build the pressure up.
That is a VENT valve hose, so the rear end don't build pressure in it. Any rubber hose will work in it's place.
Well, it's not really pressure. It's movement in the mantle that causes earthquakes.

Sinus pressure builds up from accumulated mucus that irritates the inside of the nose and causes sinus pressure. From there you have a full blown cold and can break down the mucus with medication.
Convection from the inner layers of the earth
all depends on how it is build - typically a 350 Chevy - say one that is in a pickup truck stock - looking at say 190-230 hp - but these engines can be built to produce a lot more horse power depending on how you rebuilt it.
One reason has to do with tectonic movement and the shifting of plates. It causes stress underground which releases in the form of earthquakes. The rises in pressure are results of the weight from the rocks and earth as it shifts. Aquifers can be another reason for pressure build up, which are composed of either water, oil, or gas.
When you throw the baseball, twist your wrist and you will notice it go down.
The build up of ear wax causes pressure to the inner ear thus causing tinnitus.
