This is an thread but it may help some people.
FYI there is an internal oil seal for the 22510-56040 PUMP ASSY, FUEL FEED
body.
The Denso part number is 949150-0970 or 90099-15026.
Once this seal gets worn, fuel in the feed pump and oil
in the fuel injection pump will start to mix. Also, you will
lose some fuel pulling capacity. Other internal feed pump components
such as the piston, push rod, etc. are also available.
