Heavens, Yes! SU floats and needle-and-seats are designed to hold back
2-1/2 to3 pounds of pressure. The quick fix is to install a pressure
regulator in the line (available at most any auto parts house). But fix
it soon! Excessive fuel pressure leads to carb flooding, some of which
will get into the cylinders, dilute the oil, wash down the cylinder walls
and cause all sorts of premature wear. Maybe even result in enough fuel
vapor in the oil pan to cause an explosion.....
