The Type number is usually listed on the model number tag near the model number and serial number. In many cases, models of the first Type will not have the type number listed on it. in the case of your pressure washer the first run is the Type 0 and it may not have that listed on the tag. If it does not list the Type you would just assume that it is a Type 0.
I hope this helps with your repair!

Pump Question by Jason Powell 08/25/2009
I have the vr2500 pressure washer and sounds like it builds up pressure because the engine is under a load but when I pull the trigger on the wand the pressure goes away. Then when I release the trigger it builds up again. I had the pump apart but everything looks ok. Any help would be appreciated
