I have a simpson G3000 pressure washer. The small high pressure line from the pump has developed a leak, (it's about 18"s) Do you have a part number I could use to get a replacement, or point me in the right direction? Thanks in advance.

There is a thermal pressure relief valve on the pump that opens when the pump starts to heat up.

Maybe bad pump. Remove wand and wand hose, run machine with water in. High pressure water coming out of wand/hose connection, bad wand or hose. No high pressure water, bad pump, replace.

What you have is a generic pump from china more than likely. Its built along the line of a FAIP pump. They arent supposed to have the oil changed in them at all. Most are sealed pumps but may have a plastic plug in it. If you must replace the oil then I would suggest Pressure washer parts catalog quick links Pressure Washers High Pressure... and get this item 4.5 OZ. AR64545 OIL FOR AXIAL PUMPS. It is recommended for pumps built similarly but not for your specific pump. But it should work. Good luck. W

I need to know the model of the pump you have. You are giving us the model of the engine which is a Honda GCV190. Can you tell me the model on the pump itself. It is more than likely an AR pump but I need to know . It is more than likely going to take 30 weight non detergent but some pumps take specific oil. You can also call Barens at Pressure washer parts catalog quick links Pressure Washers High Pressure... They can hook you up with the correct oil for your pump. Good luckOADXAV

What is your question ?????????????

G3000 is not much help. I have a car with an engine, can you help me get parts for it?
In general it is not a good idea to run solvents and cleaners through the pump. It tends to destroy the pressure seals ( people are often creative in what they use as cleaners) To protect the pump there is usually a siphon fitting on the high pressure side of the pump. There is usually a hose that you stick into your detergent. You then put in a large capacity cleaning nozzle and the detergent is sucked up the hose and out the low pressure cleaning nozzle. When you put on the high pressure spray nozzle the siphon valve seals and it does not draw detergent through the hose.

Can you tell me where it's leaking from.
see link for parts.

ensure that you do not have any leak not one drop coming from the output of pump to the end of nozzle not one drop after releasing trigger if so replace leak these unloader valves rely on trap pressure if pressure not trap she will cycle over and over.
