I too found the fittings getting very tight however I think it is probably to do with the shear force exerted by the aluminium manifold. I went for the same liquid sealer too.

One thing I missed - Make sure to inspect new fittings for crap before you install them!

One of the naparts brass fittings had black material in it stuck to inside of the fitting, looked to be from the machining. Not great quality control! It was stuck firm and didn't blow out with compressed air, so I cleaned all the new fittings with MAF cleaner which moved some of the stuff, and the rest I got out with a 30 calibre brass bore brush followed by a good blast of MAF cleaner.

A Donaldson replacement for factory filter P550385 is rated at 12 micron @97.5% and will be equal or better than MM filter. These are the specifications I have used to estimate factory filter as 10 micron at 95% efficiency.
A 10 micron (or so) primary filter would be my choice as I have no way of measuring the pressure drop a Z699 and Donaldson..615 will develop over time. Indeed this may be negligible.
I have a Z699 as a spare filter and may run it for 15k with a Donaldson ..316 when the time comes and cut both filters open to check condition.

Here's the inside of a Ryco Z699 primary after 4 months/11,000km. I've had no issues running it in line with the Donaldson P903316 3-micron filter kit. Fuel has been BP/BP ultimate /BP winter. Not a great deal of contamination. Thinking that based on running the Ryco before the Donaldson I'll hold off on changing the Donaldson over until around 12 month/20-30,000 km and stick to 10,000km-15,000km changeover on the Ryco's.

Thanks for all the info guys. I'll finally be installing my kit this week, along with replacing the original fuel filter as I'm not sure when that was done last by the previous owner!

Hopefully it all goes well!

I have one of these filters ready to be installed as per Hill’s install including new bracket.

What’s this that these “pre OEM filter proponents” are saying here about contaminants going downstream into injectors during filter changes? I don’t get it...

I presume containments is the paint. However, Donaldson have said that the paint is on the pre-filter side so is a non-issue.

Besides, dust can get in when changing the OEM filter as well.

Seriously though, all you do is unscrew old filter and screw in new filter and unless you are in a very dusty environment, I cannot see how dust has a higher chance of getting into the Donaldson filter than the OEM one.

That’s exactly what I was thinking hey. I was just so confused. Wondered if I’d missed something.

Must admit I work from the premise of only believing half of what I read and half of what people tell me, do a little research and make up my own mind.

What a load of .....

I've come to the conclusion, 'cause I surf the 'net a bit, that half of what you read is bull, and the other half's all sh!t!

With apologies to Kevin Bloody Wilson.
