  • Power Washer Differences on RD80701 vs RD80903 and also RD80702 vs RD80905

    Hi there people! I did search though the forums here and I think I have the answer. Just wanted confirmation and any additional differences.

    The 3000 PSI RD80701 vs RD80903 are the same PW except that the RD80903 is CA emission compliant? Same with the 3300 PSI RD80702 vs RD80905 - RD80905 is CA emission compliant?

    TIA!

    Good question. I just bought the RD80903 online thinking it had a better pump. Now I'm wondering if the extra $50 was worth it.

      A little further digging into the parts list for them shows the only difference is the Engine and Data Label:

        The RD80702 / RD80905 is the 3000 psi EFI version. The EFI version engine has more torque due to the fuel injection so the pressure washer output is rated for 3.0 GPM. 211 cc EFI engine.
        The carbureted 3300 psi version is the RD80763 / RD80964 this is rated for 2.8 GPM. 211 cc carbureted engine.
        The carbureted 3000 psi version is the RD80701 / RD80903 this is rated for 2.6 GPM. 170 cc carbureted engine.

        The EFI version is really the best unit with the latest in engine technology. The EFI RD80702 / RD80905 unit is much simpler to the end user to use. To run the unit regardless of conditions, just pull the rope and go. No choke lever to fool with because the fuel enrichment is automatically controlled like your fuel injected car. Also has no fuel shut off valve because fuel is controlled by the fuel injector. Many people have filled crankcase with fuel on generators and pressure washers in transport because of forgetting to turn off the fuel shut off valve and the carburetor float bounces filling the crankcase with fuel. The EFI system shuts the fuel off automatically for you. The fuel injector valve is always closed with the engine off.
        With a fuel injection system, off season fuel system maintenance is not as critical because of the sealed fuel system. No fuel float bowl exposed to atmosphere to varnish up in small idle passages. The EFI ECU and injector controls the fuel feed and not like a carburetor with many different small progression passages in a carburetor that relies on vacuum to draw fuel.

        The EPA versus CARB engines are typically a little different for evaporative fuel emissions with fuel lines and tank venting. Usually CARB units have an added carbon filter canister on the fuel tank venting.

          Talk to Ridgid Tech support. Only diff between the RD80903 and the RD80701 is that the Rd80903 is the California version. The pumps are the same. Home Depot web site says nothing about the Cal. version. Called HD, changed order and saved $50.
