Oversized Pressure Regulator Valve Kit
- Spring Sleeve/End Plug
- Salvages pump bodies with worn pressure regulator valve bores.

Three pump generations were produced, with varying casting hardness. The Sonnax reaming tool kit used must be matched to the hardness of the pump to extend reamer life and bore finish quality. Sonnax reaming tool kit F-36940-TL3 is for use with first generation pumps, while F-36940-TL3C can be used with all pumps regardless of pump generation. See instructions for details.
You need this if...
A Wet Air Test at the balance end circuit and at the LPC/PCA solenoid circuit at the locations indicated results in leakage at the neighboring ports, or if a vacuum test at these two locations gives less than 18 of vacuum.
