Description

 

Low spring rates, incorrect spring heights and inappropriate replacements from previous rebuilds can lead to low base line pressure. The Sonnax replacement spring 77917-08 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.

 

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.

 

Symptoms:

  • Low base line pressure

 

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.
