Is there a fuel filter on my Honda GX 3500 gas presure washer? The motor dies ever so often while it still has fuel in the tank. If there is problem in the fuel line that is plugged and where should I start looking to unplug it? Do I take the fule tank off? And what type of oil is used in the water pump itself? Is it detergent or non-detergent oil? The cap says "Moteren-Oel SAE 15 wi 40"
