CAV's what brand of filter is the best ?

[mudski]

I am looking for a quality filter,it has been suggested a Delphi what else is out there ?,And is a CAV with a glass bowl good enough on it's own or do I need a secondary filter with todays fuel I just installed my high $$$$ injector pump and I want to protect it, I have a 92 Gq Td42

My input.
I sell engine filtration for a living. I am a Fleetguard and Donaldson wholesaler. I have sold gazzilions of the CAV setups, also the Fuel manager setups etc. Unless you live in remote areas where your fuel supply is less than desired, the stock filter will be more than perfect. Eevn if you were to do a remote trip, I would just take a few spare OEM or equivalent filters on the trip as spares.
Whilst engine fuel filtration is important, on a TD42 its not as important as a newer common rail motor as they require much higher fuel pressures and tolerances are far less.
The other issue that has risen its head is some people have added an extra filter setup and then they have experienced some performance issues. This is due to the extra fuel flow restriction from adding a secondary filter. This is moreso for th CRD motors though. Not so common though but it can happen.

All in all. In my opinion. If you want to protect your IP. Change the stock filter more often. And use a quality filter. I change mine every 15 though regardless. And my Patrol wouldn't even see 15k in a year.
