Locate and Connect the Diverter Valve
The diverter valve is designed to accept full system flow, continuously divert a portion of that flow to the
lifter(s), and pass the remaining flow on to the packer control valve. The amount of flow that is diverted
is adjustable, so the same valve that feeds one lifter can also be adjusted to feed two lifters.
Adding the Perkins diverter valve to your system will slow down your packer cycle by several seconds,
whether you are actively using the lifters or not. However, this is usually an acceptable tradeoff, since
the Perkins diverter valve doesn’t generate much backpressure or heat, and it allows you to use the
packer and the lifters simultaneously.
With the system off and depressurized, find the pressure line that feeds the packer valve and disconnect
it. Connect this pressure line to the “IN” port of the Perkins diverter valve. Connect the “OUT” port of
the diverter valve back to the packer control valve where the pressure line originally was.
The fittings to do this will vary from truck to truck. The Perkins Tap-in Kit generally gives you the
required fittings, but due to the wide variety of trucks, changes made by the OEM, as well as the
possibility of other aftermarket parts, especially on used trucks, the fittings you need to make these
connections may not be included in your kit and will have to be purchased separately.
