IPR for HPOP

jross6 · Dec 9, 2012

I recently replaced the O-Rings in my HPOP and upon removing the HPOP I noticed there are threads at the end of the IPR (external) with nothing fastened to it to prevent the sensor (?) from sliding off. I had service done on my truck about 1 year ago in relation to the truck not starting. They replaced a sensor on the HPOP and assume they either did not put the fastener back on or it came off.

Can someone tell me or send me a picture of what fastens to these threads so I can get a replacement?

I have no picture, but you are looking for a stamped steel nut. Don't forget about the spacer, which may have fallen off as well. I would take a good flashlight and look down in the valley under the hpop. You might have to get a little greasy and start fishing around down there. If you don't have a sparkling clean engine, the nut and spacer will probably be buried under the gunk

Thanks for the information. Do you know if these parts are available at the dealer?

Only if you buy the whole ipr. That's pretty expensive

Actually, the IPR o-ring kit comes with a new spacer and stamped nut.

Should be around $30-40 at the dealer.

I appreciate the information and I did find the stamped nut in the valley last night minus the spacer. I am thinking about making my own spacer as it only looks like it just keeps the sensor from coming off. I was also going to find a nylon locking nut to replace the stamped nut.

Any suggestions?
