ok i just never knew correct name,is yours a stacked piece held in place by a snap-ring? or barrel and plunger style?

[greasltn]

I don't have the OBS, I was looking at the lube flow chart in the 7.3 bible.

would you happen to know if this would cause a no-start? I replaced the oil-cooler but now have a no-start,

[greasltn]

It could cause a no-start if your HPOP is not full. There is a plug on top of the HPOP you can open and top it off with oil. If it doesn't start after filling up the HPOP, you have another issue that just happened to come about when you did the cooler. Let me know what you find out and I'll do some more research.

Update, It now runs! "greasltn" i really do appreciate you helping out with this! What i did was, removed oil pressure sensor and the other plug on the HPOP res. I did fill this after the oil cooler re+re,but checked again today and it was nearly empty. So after refilling i craanked on it but still nothing.Next i remoed the connection leaving the GPR and gave it about a 1sec of ether and then it started not sounding great but idled itself out,left it running for about an hour with no issues, topped up the coolant res. and shes good to go.Also the oil gauge neddle stays steady at the M on "normal"
So again thanks for the help!
