A damaged 35594837 diaphragm often leads to improper fuel regulation or hydraulic pilot pressure drops. If the vulcanized rubber is cracked, the air-to-fuel ratio shifts, causing the engine to "choke" or fail to reach maximum RPM. Replacing with a fresh 35594837 part usually restores immediate throttle response.
Watch for fluid weeping around the control valves. If you see oil or fuel seeping through the vent holes of the pump housing, it is a 100% confirmation that your 35594837 replacement is overdue. Continuing to operate with a broken diaphragm can lead to contaminated systems and expensive pump failures.
