Over time, high fuel pressure spikes can significantly reduce the life of your fuel pressure sender. Restrictor fittings, also called fuel pressure snubbers are designed to eliminate that problem. They will work with any type of fuel. You can use a restrictor fitting to help isolate the sender from engine vibrations and reduce back pulsing of the fuel system, in order to increase the life of the sender.
