- About This Product
DescriptionThis 1/8 NPT snubber is made specifically for Cummins 5.9L diesel engines and dampens the violent fuel pressure spikes.
It is highly recommend that you use this snubber on trucks with the VP-44 injection pump to dampen the fuel pulsations (hydraulic hammering) created by the injection pump.

Fuel pressure spike fixed

Its a good idea to install a snubber for the fuel pressure sending unit when running an aftermarket high flow lift pump. This works very well to stabilize fuel pressure indication fluctuations and is easy to install.
