Not sure if this will be usefull to anyone, but thought I'd post this up as info for those out there.
It refers to the fuel filter on a 02GV, V6
I purchased a
filter kit from ebay, a company called 4wd_products. The kit included air, oil and fuel filters, although at the time I ordered it I was only after the fuel filter At the price I thought why not give it a crack.
I've not fitted the air or oil filter yet so can't comment. I have however fitted the fuel filter so here are my thoughts/observations.
First the pic (disregard the red protective caps)
Inlet
OEM (or0 at least I presume it's OEM as I couldn't find any info on the filter itself)

4wd_products

Outlet
OEM

4wd_products

There are some slight differences in the direction the pipes face when the filter is correctly fitted to the bracket. The 4wd_products one can also have the inlet face to the 7:30 (roughly) direction when fitted properly also.
this made it slightly more difficult to fit the hose up but in the end caused no real concerns.
The body of the 4wd_products filter is smaller diameter than the OEM which means that when you tighten the bracket up to the filter properly, the holes to fit it all up to the car don't line up spot on anymore due to being closer together (eg 110mm apart instead of 130mm apart - using BS #'s to give the example).
What I did was to make the top elongated hole a slot.
I used a thick body washer and a slightly longer bolt on the top mount.
Put the bolt/washer in the hole loosely and then fed the bracket up under the washer
Fit up the lower bolt then tighten it all up nice and tight.
Then fit the hoses as per normal and then do the usual leak checks once finished
So far it's not leaked or had any other problems.
When I get to about 10k kms I'm guna pull it out and cut it open to see what's inside. I'm guna cut the OEM (which I've saved as a spare at the moment incase this new one fails) apart at the same time and compare.
