It is filled by the lube oil pump using engine oil. Some guys like to change it, but it's not really necessary either. Cheers!

Wow! So if that one plug gets a bad connection or the wire starts going south... any of us could have a no start mystery that we could spend weeks chasing down!
How many electrical connections like this are there on the Powerstroke?
So far I know of three now:
1. Camshaft Position Sensor
2. Injector Harness (Under Valve Cover Harness)
3. Now the Injection Pressure Regulator
Would a check engine code let me know which thing is unplugged on my van (95 Powerstroke Diesel)?
And... Lastly, what does the connection from the Fuel Bowl to the Injection Pressure Regulator do?
thanks!!
