Cause:
Low spring rates, incorrect spring heights and inappropriate replacements from previous rebuilds.
Correction:
This replacement spring provides a resultant idle base line pressure of 72psi, consistent when compared to the OEM orange spring.
Low spring rates, incorrect spring heights and inappropriate replacements from previous rebuilds can lead to low base line pressure. The Sonnax replacement spring provides a resultant idle base line pressure of 72 psi, and 82-85 psi cracking pressure, which is consistent with the OE orange spring
The Sonnax replacement spring is stronger than many alternatives, and allows increased pressures throughout the stroking action of the pressure regulator valve.
Note:
Low line pressure resulting from worn boost valves, a worn pump bore at the pressure regulator valve or pump pocket wear will not be corrected by this spring.
