@johnstern

So in default replacing the fuel filter will directly replace the Fuel PR as well?
(just to be clear that they are the same piece)

Yes. That is correct.

Edit-To put you mind at rest here is the link to the realoem.com diagram for the fuel filter/fuel pressure regulator assembly for your car. I guess you can buy the FPR separately, but you can't buy the fuel filter without the regulator. Go figure!!!!

Mein Auto: 02' 525i
Unfortunately the fuel filter is sold everywhere without the regulator to unsuspecting victims that can't use it.
After ordering a replacement fuel filter on eBay for my 02' 525i a few months back, I finally got around to replacing my fuel filter last night, only to notice upon removing the original, that my new replacement filter only allowed for one line in and one line going out. The old original had two in both directions. "Hmm...should have learned my lesson about 'O-E-imitation-Chinese-junk-M' parts a while back, I thought, but this was from one of my earlier purchase, before having horrible luck with the stuff.
Anyhow, I walked into O'Reilly, which had access to a nice stock selection up the road they don't disclose, and nearly anything BMW can be picked up by the late afternoon/ early evening. Surely they would have it, I thought, but all they had were the same as mine.
Confused by fuel filter. Not feeling very resourceful or inspired at this point.
So I walked into the Autozone across the street on my way home last night, only to be presented with the same filter.
When I thought that I was out of luck in my mission, a BMW-e46-owning employee of Autozone came to the front after consulting her boyfriend on the phone in the back.
Unbelievably brilliant what she told me to do: she actually sent me back to O'Reilly Auto parts, with instructions to ask for the fuel filter with the regulator attached.
Unless you hear otherwise in this thread, assume I am successful picking it up in the morning as described: fuel filter always should be ordered WITH regulator.

The problem you are having, as explained above, is because all these aftermarket parts houses are selling you the wrong fuel filter. They might as well have sold you a fuel filter for a '49 Buick-same result: it doesn't fit. All MY 2001-2003 E39s sold in the US take the filter with the integral FPR. If you had gone to the dealer or used one of the mail order BMW parts houses (Bavarian, Turner, Pelican, ECS, etc.) you would have gotten the correct filter. The filter without the integral FPR would have fit my 2000 528iT perfectly. My FPR is clipped to the 3/2-way valve located just in front of the fuel filter.

When it comes to fuel filter, oil filter, order online for Mahle, Mann, Bosch.
Local auto parts stores rarely have the correct filters, adding to your aggravation.

Mein Auto: 02' 525i
Thanks @c90 @bluebee and @johnstern for your contributions to a thread started by... Um, @deathstroke.
Anyhow, sorry for delay and here's my update:

FUEL INJECTORS CLEANING
I have cleaned the fuel injectors and their seats in the fuel rail, being careful not to knock debris inside. Still need new o-rings.

FUEL FILTER HOSE CONNECTIONS
I replaced the hose connections and clamps connecting the lines from fuel tank to the fuel filter (in and return). Coming from the fuel filter to the engine bay: Is the hose connection from fuel pressure regulator smaller in diameter than the other 3/8 hose connections? 1/8" maybe? And it goes to fuel tank breather valve on 02' 525i?

LEAK FROM FUEL FILTER - UNKNOWN REASON
The connection on the fuel filter going to the engine with liquid gas isn't holding though, and I'm seeing a drop or so by the minute when ignition is in key position 2. *I don't get signal to the starter and my car's been immobile for a few weeks, but Ill post in electrical page for that one.

FUEL pump relay I replaced a few weeks ago successfully.


CCV valve and connecting hoses:
Replaced CCV valve and connecting hoses. Still need new o-ring for oil dipstick.
@bluebee : Do our 02' 525s have the fuel pressure regulator line going to the fuel tank breather valve (identifiable by the way in which it is held hanging from a little slit in its rubber casing, right? Or is it one of the lines on the F connector on the air intake?

Lastly, how in the world did anybody get the fuel filter back onto its large clamp, attaching it back to the body?

O-rings from dealer are $5 each, with 12 needed to fit an i6. I'll go generic from the hardware store for a total cost under $6 rather than dealer cost of $60. Noticed I had swapped fuel injectors from an older e39, possibly reason for no start.

A listing of all the o-rings in the E39 can be found by typing /o-ring f3 in the bestlinks:
- Glovebox printouts for emergency use (1) and how to save $ money to qualify for free shipping on UPS/DHL/USPS/FedEx by stocking O-rings & gaskets & bulbs & vacuum hoses & fuses & wiper blade inserts & belts & bearings & oil filters & cabin air filters & engine air filters & fluids in your garage whenever ordering from the recommended parts suppliers.

I don't know if the fuel pressure hose sizes are listed in this thread, but typing /hose f3 nets me the vacuum hose sizes:
- How to locate all problematic (between 1/8" & 9/32" ID) 3.5x1.8mm, 3.3x1.8mm & (between 17/64" & 9/32" ID) 7mm ID vacuum tubing (single material), vacuum hoses (multiple material), 3.3mm OD curved vacuum pipes (rigid tubes), 3.5mm & 7mm ID vacuum endcaps (closed end) & 7x3mm manifold o-rings (1) & 7.52X3.52mm and 9.2X2.8mm fuel injection o-rings (1) & gaskets (1) on the M54 engine & where in the USA to get new vacuum tubing & vacuum caps (1) & what SAE sizes to get for all the metric M54 engine vacuum tubes, hoses, pipes, and caps (1) & correcting the F-connector errors in the realoem diagrams (1) & finding the ends of hard-to-locate vacuum tubes (1) & sorely needed clarification on how the M54 CCV vacuum port works on the M52 CCV valve connection to the fuel pressure regulator connection (1) & how to make, borrow, or buy lean-condition misfire test tools to test for vacuum leaks & lean conditions (1) (2)

If those threads don't show the size for the fuel pressure hoses, we should start a thread to determine all the fuel system hose sizes.

There are three of them, and one on the dipstick guide tube, just so you know. (Pictures are in the o-ring thread.)

Please add value to all this information by telling us what size o-rings you bought, and what you found out the solution to be, as we all stand on each others' shoulders.
