Base oil pressure question

A friend is working on a 05 f-450.It stalled and will not start. He replaced the HPOP because there was no oil pressure. Still no oil pressure. Checked the base oil pressure at sending unit port. Nothing! But it will fill the oil filter housing.
So my question is why is there enough pressure to fill filter housing but will not push oil out of the sending unit port?

Thanks in advance

Was the oil filter in the housing when they were trying to check pressure?

^^^ That is the $64,000 question.... Are there any members that actually remember this question or even the name of Roy Rogers' horse?

Bad low pressure oil pump...

If a power stroke 6.0L doesn't has HPO pressure, first check the LPO.

You need at least 60PSI in the LPO for the HPOP to start pumping to the HPO system.

Also you could have a broken by-pass valve, wich is located just down the LPOP. You can fix this by adding a coin before the spring, just over the nut that is an allen drive.

Yes filter was installed.
I was thinking he should just go ahead and replace the LPOP.

Need to pull pump apart and see if it's damaged. If it looks like needles went through it there will be a lot more work to follow. The truck I bought had this problem. Lifter went bad and tore up the cam and oil pump. It also ruins the front engine cover.
