Poor line rise results when excessive wear occurs in the boost sleeve assembly. This prevents the pressure regulator valve from being stoked to the high line position. Valve wear can also result in the boost valve sticking, causing unintended line rise. Sonnax offers a direct replacement boost valve and sleeve assembly.
