• BMW HPFP REBUILT using...
Sorry for the full video as my video recorder stopped working and my hand was wet with oil to check the recording. I will be doing a video again after a while, this quick upload is for anyone in hurry of fixing the HPFP.
This is just the basics of how to repair the HPFP if you have patience.
This to take care of.
The X-ring must be tight fit on the spring type compressors 1.8mm thickness and 20mm inner diameter for the x-ring . Make sure it's tight fit(O-ring is prone to more issues).
The Oil Seal size is 22mm outer 11mm inner and 7mm wide.
Oil I have used is 85/90, I don't know which oil is best for this, just chose it on a guess.
The Solenoid with electrical connector has to be removed before immersing completely in oil. The chamber that i have shown has to be completely filled with oil and the diaphragm hole too.
Just did the repair so I am not sure how long it will stay.
