Can someone please help me identify the part circled in the photo. I have done quite a bit of searching and even running part numbers and even still I have not been able to identify it.

That is the Rack Position Sensor.

Thanks guys. This is my 3rd Swap into The Toyota 4x4 pickups but it's this first time coming across this mechanism.

The rack position sensor started ~1984. It is only for the EGR controller and is not necessary. Downside is that it makes it much harder to get at one of the 3 mounting bolts.

Scary that the delivery valve outputs aren't capped, with all that gunk on the IP. I suggest turning it over with the engine to flow diesel out each port before connecting the injector lines.

Can you just remove it or does it need a custom cap made to seal whatever is behind it?
