I got the XF Ute a month or two ago after sellinf my beloved EF. It has been nothing but grief courtesy of an exhaust "specialist" who thrashed it so hard (after fitting a 2 1/2" exhaust) that he bent and threw the pushrod in 5 cylinder. I've got the engine pretty well back on its feet again but I suspect he's also cracked the head gasket as 5 cylinder's oil around the spark plugs isn't as dark the other cylinders - I'm not looking forward to having to pull everything apart.
The XF has always chewed through the juice and I'm a bit of a leadfoot, but when I was looking to check if my coolant reservoir was leaking (it is) and after turning it over in the drive way a few times I noticed I'd lost some fluid on the driveway. Smelt like fuel. It seems to be coming from directly under the fuel intake and it doesn't leak unless the engine is running. I'm thinking fuel line, but it might be the tank.
If it is the fuel line how do you get at at it, do I have to pull panels off? Same goes for the fuel tank, do I have to pull the exhaust and gearbox out?
Panels shouldnt have to be removed...the fuel line in my carby XF runs into the engine bay from the passenger side wheel arch (metal tubing) and into the engine bay..from there it branches out into rubber hosings..
I believe the fuel line runs along the passenger side chassis rail to the fuel tank (metal tubing)..but i havent had a real close look at it..
could be one of your rubber hoses deteriorated? Is it EFI?

Not sure if this applies to other than the sedan, but the fuel line for the XF runs along side under the passenger side as metal, rubber hose to the fuel pump, then metal from the pump up to the carby inlet.
Unless the pump/carby metal pipe is fitted SPOT on, it tends to leak either at the carby or the pump. Usually at the carby, and it dribbles down everywhere, usually discolouring under the float bowl.
Give it a squiz and see if the pipe is wet while running.
i just had a look at my xf and where the fuel lines go and all you have to do is disconect the fuel filter in the engine bay ,from the metal pipe that goes into the wheel arch.
then look in the wheel arch .where the wheel actually is and you will see a bolt undo it ,then look under the car and there will be a rubber hose undo that and take out that first piece of metal pipe .
after that 1 look under the car again and there will be more bolts to undo ,just follow the line up and unbolt all bolts .then there will be a rubber hose up near the tank area disconect that and you can take that line out .
carefull though as the line is easy to bend and break and you have to get it through a little tricky part as well should take at most 20 mins to get out .
after it is out try to blow the line out with compressed air .
if you need to take the tank out you will find 2 bolts on one of the sides of the strap that holds the tank in place .undo andthe tank should lower .but should be care full ,.only really do it if there is nearly no fuel as well.you will also have to undo some rubber hoses .,maybe .
installation reversal of taking the tank out .
hope this helps lets us know how it all goes .

It's a carby job. Cheers for the advice, I'll get on to it first thing tommorow and check it all out. Probably is a hose. I know the fuel line was a little leaky after I fitted a Ryco inline fuel filter but I've refitted with new clamps and it doesn't seem to leak. I'll have to keep an eye on the carby when running it, I'm going to play around with the rockers tommorow as I think one of them (probably 5) has been overtightened- something in the engine knocks at high revs.
As for the exhaust guru I'm with subsbligh35. I thought about having a word with fairtrading but it's difficult to prove it wasn't rooted before I dropped it off. The guys I'm really pissed off with are the little pricks who keyed my front right panel, pinched one of my socket sets out of the tray and slashed a brand new 14" 215 on Thursday night, 6 days after I got 4 new ones. Got to love school holidays.
I've been buggering around under the thing day. I've replace the fuel line either side of the inline filter I've installed so it is all new from entry in to engine bay to carby- it looked like it was dripping on to the fuel return line. Fuel is definitely dripping down on to the bolt that runs upwards in to the chasis directly below the fuel cap. I got a bloke at the local auto shop to have a look. He's a Holden bloke, but he reckons it's either the fuel return or a pinhole in the fuel tank. I am still fairly sure that fuel only leaks either whilst or directly after the engine has been running. It seems to leak more after it's had a decent drive.
Now as far as the fuel tank goes, it appears that the tank is above the some steel plating, I can't see the strapping at all and it looks like I'll have to pull the exhaust and driveshaft off to pull it out. To inspect the fuel line after it rises back in to the body I suspect I'll have to pull off a couple of removeable panels inside the tray.
If anyone's done this before or has advise please give a yell.
Geez I feel clueless. I've checked out the ute again today. Now the fuel is definitely leaking out from directly below the filler. I got in the tray and pulled of the panel directly above the filler and the filler and the fuel hoses around the filler are in pretty good condition - none of the appear to be leaking. It's definitely not the filler 'cause it leaks even when there's low fuel. The leak could be from the fuel delivery or fuel return lines, but is internal and between the filler and the tank. I noticed a lockable door below the tailgate and there is a decent sized recess in to the chassis, I can't open it until I rip the tow bar out as it is preventing the door from opening - Would this be for the spare tyre (I keep it in the tray) or is it possible that this is where the fuel tank is?
There is no obvious strapping in the undercarriage so if the tank isn't here then I think I'll have to pull the exhaust and drive shaft off to get at it.
Has anyone out there changed a tank or the internal fuel lines on an XF ute?
The fuel tank in the XF's is under the big panel in the floor of the tray that sits behind the cabin. There are a heap of self tappers to remove to lift this panel out. Tank and lines should then be really easy to inspect. Also remove the left hand panel on the side of the tray immediately behind the cabin, and check the rubber fuel hose between the fuel filler and the tank. These go hard with age and may also be a problem.
