Below is the online discussion (minus names) I had with one of the RYCO techs on the Z503 and Z9 filter. The Z503 is the one they specify as a replacement for the genuine filter for the 4.2 turbo diesel GU. As they say if you do it be it on your own head, neither RYCO nor myself suggest you use the Z9 as an alternative. Read from the bottom up, bottom email is my first etc.
Looks like it might be worth considering.
--------------------------------------------------------------
The only issue you may have if anything was to go wrong you would not be covered by the Ryco warranty as it states you must use what is catalogued.
We normally bring a filter like this out because it is closer to O.E specifications and we have to keep within the O.E standards..
You could use it but as they say on your head be it.

Thanks, think I'll do this as the Z9's are much, much cheaper than the Z503's which are listed for my GU 4.2 turbo diesel patrol. Any reason for this, is it just economy's of scale?
------------------------------------------------------------------
Correct but not the other way around!
-----------------------------------------------------------
So there should be no reason why I can't use a Z9 filter in place of a Z503 is this right???

Thanks for the reply. I have a couple more questions leading on from your info.
1. I gather the relief valve is if pressure builds to high it will open. Why doesn't the Z503 have one and is this the correct logic as to it's use?? CORRECT
2. Since the Z9 is larger in physical size does this equate to more filtering capacity ie more filter paper so takes longer to be fully contaminated??? There is not enough difference with these two to make a difference.

Thanks for the email.
Below is the specifications I believe you are after.
Hope it helps!!
Kind regards
Z503: Thread Seam Diameter Height Seal

I've been trying to track down specification/data sheets on a couple of filters. The data I'd like are on your filters Z503 and the Z9. Are you able to email me a copy or tell me were I can locate them. Basically after filtration and size specs.
