There really isn’t any info out there on what parts this engine uses, and it doesn’t use all GX670 parts.
[COLOR="#FF0000"]Oil filter.[/COLOR]
Fram PH4967
Motorcraft FL836
Purolator L14476
Wix 51394
Bosch 3311
[COLOR="#FF0000"]Fuel pump[/COLOR]…some people have had issues with it. Any Honda GX610, GX620 or GX670 pump will fit. Inlet, outlet and pulse.
[COLOR="#FF0000"]Oil capacity[/COLOR]. The manual specifies 2qts. Mine smokes if I go over 54oz of oil.
[COLOR="#FF0000"]Fuel Filter[/COLOR]. The one that comes with it is junk. I used a Wix 1/4" inlet/outlet.
IF you install a Drainzit, it’s a 12mm plug.
