2006 XK8 Victory Edition Convertible....

I'm planning to change what I assume is the factory fuel filter when I perform the 90,000-mile service on my wife's car in the next month or two. I've read about owners purchasing aftermarket fuel filters that do not fit due to differences in the way they attach to both sides of the fuel line. Some filters' fuel lines are screwed into place while other filters' fuel lines are clamped into place....

So how do our 2006 XK8's fuel filters attach, and what brands and model numbers are known to be a perfect fit?

Thanks for your expertise....

 

Not an expert, but the AC Delco GF 652 should fit. It is listed as fitting '96 to '06 models. I got the filter from Rock Auto ($13) and had an indie install it for $41.

 

If I recall correctly, it is the screw in, not clamp style. I know it is shared with a bunch of GM vehicles and is a common one. I'm running a Wix filter that I picked up locally. I believe I specified something like a '93 Firebird since sometimes the parts places gouge by looking up Jag vs. GM for the exact same part number. Someone should be able to pop in the details for you, otherwise I can look into my records and see.

 

Keith,

How much trouble did your screw-in connections give you when you removed your old fuel filter? I've read about some of them seizing up due to rust and I'm not crazy about using a torch to loosen up fuel filter fittings. Could be a recipe for disaster....

 

The last screw connection fuel filter I had problems with was on an XJ40 which is a similar filter bracket and hex connector design.

It got to the stage I knew I was going to break a fuel line if I put any more pressure on it trying to release the connection. Cutting the filter in half made it a lot easier to hold the connectors still and rotate each half of the filter in turn to get them off.

Last parts guy I asked for the filter by number told me that the reason they probably
did not have them in stock was that "they probably aren't popular".

That's when I told him they were used on most GM vans and pickups of the last 20 years.

 

Update:

It appears that the fuel filters on the 4.2 engine XK8s use the clip-on type connections to the fuel lines, not the screw-on type. I called our local Jaguar dealership's parts department yesterday and had them pull the official Jaguar fuel filter out of the box and take a look. It uses the clip-on type connections. The part number is C2S20977. Their discounted sales price to me is $108.12 plus tax. Needless to say, I won't be purchasing one....

Oops! I sold my 4.2 before it was due a fuel filter change. I should have looked at JTIS before making assumptions.

Graham,

My JTIS CD shows that same line drawing of the fuel filter for the latest version of the car it covers (2004 model year). I hope that line drawing is indeed accurate. I won't actually know until I pull the factory fuel filter out of my wife's car, but the fact that the replacement fuel filter our local Jaguar dealership sells for our particular VIN is indeed a clip-on type gives me at least some level of confidence. We'll find out when I do the 90,000-mile service....

I've ordered a Motorcraft FG968B fuel filter from amazon.com. Total cost was $11.29 with free shipping. I've been told that its cylindrical body is a bit slimmer than the Jaguar factory filter, but a few wraps of duct tape should make it fit snugly in its bracket....

 

Jon,

I can find several images for P/N C2S20977 clearly showing it's clip on. Here's one example:



Normally Jaguar parts costs are considerably lower in the UK than they are in the USA but the best OE I can find for the fuel filter is £55 ($82). The earlier pattern for the 4.0 Litre is approximately 10% of this!

Oops is right. I too, just assumed it would be the same all the way through. I didn't have any trouble getting my screw on type apart gratefully. The clip on should be pretty decent too.

Just be glad it doesn't have those stupid banjo fittings with crush washers. My wife's Audi A6 has that style and would constantly leak when I replaced it. I stripped one out trying to get it to stop leaking (gratefully they aren't too expensive on that car) and finally got the second one, with another fresh set of washers, to not leak.

 

Jon, if the solid line is like the 2000, very difficult to extract from the filter. Mine worked better and had a bit more flexibility in the forward pipe, so pulling back on the rear while making a big effort on the front one was the answer. OPPS, forgot how big you are, gently Jon, gently. I found removing the whole bracket was the ticket after breaking the nuts loose, which may not be the case on the 2006.
For those that don't know, Jon is larger than most. I had him tighten up a nut on the rear shock and he lifted the other side of the car off the jack stand, now that's what I call in the torque range as f.......... tight. LOL

Thanks for the tips, guys. I've learned the hard way to take my time and rely on gradual force, not bursts of brute strength. I've ruined far too many old and new parts and assemblies over the years by getting mad at them and then forcing the issue. When such behavior takes enough of a toll on my wallet, I eventually learn from it....
