Hey guys,

So I didn't get a response in my last post, but moving along, I think I found a potential issue.

For those that did not read the last post, I did injector O-rings, lift pump, all new rubber lines in valley, and glow plugs on my 1995 PSD.

When I took the truck apart (and removed the fuel filter canister) The IPR was "apart" (I did not know what it was at that time, but I do now). The crappy little nut had fallen off the back side, and the magnet pulled off. I see NAPA and Auto Zone call this the fuel pressure regulator, but from what research I turned up here, it looks as if this would regulate the oil pressure to the injectors as opposed to the fuel.. CORRECT?

I put it back together, but backwards.. I put the "top hat" looking spacer towards the HPOP, and the magnet on the end, then a nut.

My questions are this: Being I put this together "backwards" will it affect how it works, as the truck does run as is, however not quite right still (but has been sitting for a long while, and I am going to clean the fuel press. regulator up tomorrow in hopes to help remedy my hard start)??

Question 2: The goofy little nut that holds the magnet on is missing, so I found a suitable standard nut (1/2-20 nut threaded on perfect) and tightened it up nice and snug.. how tight should it be tightened? The magnet shouldn't be able to wobble around, right?

Hopefully someone can answer my questions this time.

Thanks in advance
Brad

Be sure to correct how the solenoid and spacer are. I am sure you will see a difference.

Snug is good. It needs to be tight enough to not come loose. No, it should not be able to wobble around.
