  • Pressurized Fuel Filter

    While looking up some part number, I came across this filter called "Pressurized Fuel Filter" with part # 23390-0E011. I didn't know GD engines have another fuel filter aside from the one in the accumulator. How often should this be replaced? Can't find any guide on how to replace this filter.

    that fuel filter is explained in this article - Toyota GD series diesel engines (

    Its not a maintenance item as such , its there to stop further damage to the commonrail system in case the fuel pump fails . In older commonrail designs , if any tiny metal fragments escaped the fuel pump those fragments would be pushed into the rail , injectors , the fuel lines and flushed back into the fuel tank. This would mean a replacement of all the affected items , easily a $15k + repair.

    It can be replaced by removing the starter motor but not required as a regular sort of thing
