To order this unit, please call 727-562-5488 m-f 8-5 est. We ship with great rates throughout the USA. We stock this unit.




This unit will need a fuel tank, 1/4" fuel hose and fittings (1184, 2119) to connect the fuel hose (fh) to the tank. You can purchase an aluminum fuel tank or poly fuel tank online or locally. We offer the fuel hose (fh) by the foot.


Please purchase a length of 3/8" (agy06) or 1/2" (agy08) yellow ag hose. We offer it by the foot.


Purchase two barbs for the bypass hose. You need a hose barb (1175) for the outlet of the unloader and a 4784 for the tank. The barb at the tank and bulkhead is included in the pl-4-to or pl-4-ta kit.


Purchase a battery for this unit. You will receive a small, empty battery box and strap.


If you need a nozzle holder, purchase it separately. You will receive 5 loose quick connect nozzles.


Purchase a 6741 chemical injector and quick connects (3878, 2401), a length of 1/4" clear braided poly hose (2903) and filter (tf-c) for this unit if you need and injector.


Unit arrives with coupler on the outlet and plug on the inlet of the gun. We recommend switching the plug and coupler.


If you are tired of the pressure trapped unloaders damaging everything under pressure when the trigger is released, this 5.5 GPM pressure washer is your choice. Pressure trapped unloaders are notorious for leaving ping marks where the balls from the couplers meet on plug collars when laying on and off the gun repeatedly. The grooves result in damage to the O-rings inside the couplers. High pressure hose and high-pressure guns will last longer when using the flow sensitive k7.2 unloader. You will stop fighting the stiff, high-pressure hose when you switch to this unloader. Your body will stop taking the abuse. If you suffer from shoulder pain and tendonitis, this may be your ticket!


We strongly recommend that you purchase our pl-4-to or pl-4-ta kit for a tote or a horizontal leg tank which has almost everything you need to correctly plumb this unit. Add the items above to complete your installation.


Upsizing your hoses will prevent back-pressure to your pump, help your valves and high-pressure seals last longer, prevent your safety relief valve from spraying water, help your pump run at a cooler temperature, supply enough water to your pump using the 'double your supply hose id in relation to your inlet port' rule and keep your pump cooler leading to less down time. Double check your surface cleaner hose to ensure that it is 3/8" id instead of 1/4". 


Always use medium thread lock on your high-pressure fittings instead of Teflon tape. Teflon tape will end up in the pump valves or clog nozzles.



If using a chemical injector, install the injector only when in use and install it several feet downstream of the unloader to prevent back-siphoning into the unloader/pump manifold. Did you know you can use dual port chemical injector to apply chemical at an even stronger ratio? Try the gp100790. It has two barbs. Try one of our original slotted PVC filters (tf-di) with two barbs made especially for this dual ported chemical injector.


We recommend a minimum of 100-gallon water tank or ibc tote.


Add a high temperature Hudson float valve (Hudson-ht) and Hudson float valve installation kit (Hudson-a) to prevent over-filling your water tank. The Hudson float valve will automatically stop the flow into your tank when installed properly in the headspace of your water supply tank.

We highly recommend adding the best high pressure 3/8" ball valve (6292) to this order to allow you to turn off the flow of water to switch from the gun to a whisper wash classic surface cleaner (4345). You will need to ask for two nozzles 3.0 25 degrees for a two-nozzle spray bar.


The 19” whisper wash classic is the perfect complement to this cold pressure washer. Keep in mind that the wider the surface cleaner, the slower you will move. You can choose any surface cleaner that your heart desires and just about anyone will sell it to you but understand that the 19" surface cleaners are the best match for the 5.5 GPM pressure washers. Whisper wash will customize the handles, the spray bar and wheel set-up to meet your needs.


For example, if you want the classic handle on the ground force with a 4-tip bar, they will assemble that custom surface cleaner for you.


As with any pressure washer, do not adjust the unloader. The unloader is set at a spike pressure of 200 psi above the operating pressure of the pump and meant to be left alone. If you need less pressure, change out the nozzles to a larger orifice and never smaller than what is called for using factory specifications using GPM and pressure. This unit requires an 8.5 orifice or larger nozzle. You can add a 6540-5 Jrod kit & the Kyle Davis long range shooter nozzle (sn4) to this pressure washer to experiment with pressure and distance.


Pair this unit with a 1/2" all-flow 17 GPM air diaphragm Softwash system for the most efficient cleaning rig. The 1/2" all-flow can be used to Softwash everything from the roof to a giant commercial building and the 8-gpm pressure washer can be used to rinse using either the new m5ds adjustable nozzle ($59 and awesome!) Or using a big 0050, 0060 or 2560 nozzle on a gun/wand assembly with low pressure.
