Important Notes

• Cannot be used in a dead-head fuel system; must be plumbed after the fuel rail. Use the MPR for dead-head plumbing.
• Dampers CANNOT be used with mechanical fuel pumps or direct injection. Those create pressure pulses too strong for the diaphragm and will rupture it in short order.
• Damper base static pressure requirement: 40 to 105psi
• Use a wicking medium-strength thread locker on the vacuum fitting
