inquiring about the fuel system, do these cars have a in line fuel filter?
model XKR 2011 if so where is it?
also location of the fuel pressure test port?
down loaded on line service manual but it has confused the heck out of me.
any help is greatly appreciated.
The fuel filter is located behind the left rear wheel in the wheel arch. Follow the lines up to where it is located. Attached is a picture of the fuel rack. The pressure port is the piece that looks like a cap. It is on the left side of the fuel rack.
Oops. Actually, there ISN'T a 'per se' fuel filter on the 5.0 cars. All there is would be a sock type filter around the fuel pickup inside the fuel tank.
The fuel pressure 'port' in in the OBD2 port, using a reader which can read those codes. Since Direct Injection, you'd blow something up trying to read the high-pressure side since Really High. Low pressure may have a port somewhere, but why do that when OBD2 has it all digitally?
Actually I asked because I found an old service receipt with a comment about "recommend fuel system service" which tells me very little.
Can it mean a fuel injector flushing is recommended?

I reckon it depends on the context. Many shops use that as a generic “pay us to pour a bottle of cleaner in the tank”.

Not to belabor the point but what is Direct injection? I am familiar with gang injection and sequential injection. How different is direct injection?
and please define "really high" pressure. Not aware of fuel injection systems beyond 100 psi. Just trying to learn.
related?? One of the modifications I did was a filter (and magnet) on the power steering system. I can appreciate its not modern thinking but I can't fathom not having a filter on the fuel system.
On my boat, I have 3 filters on the fuel system... surely a car deserves one?
That is a standard Chevy filter that mounts on the rail. I have put 100,000 miles 3 times on one. Its good.
But bear in mind the injectors on our 5.0 cars also clog from the outside. So fuel injector cleaning is the best method.
Don't understand clogged from the outside? Doesn't appear to be a way to directly put a product like seafoam thru the injectors.
Manual only says put some stuff in the tank and then hook up a cleaning agent to clean the air intake passages. Please stop the cryptic nonsense and give helpful info.
You may feel better but leaves us newbies so so confused.

I dont know what is cryptic or nonsense about what I wrote for my friend.
Whats cryptic to me is the Southern sense of politeness, I dont care for it, you can keep it.
Ask the guy who thanked your polite post to explain to you why he has had to change all his injectors and never his fuel filter.

Rudeness is easy, Politeness is harder, I thought the Brits are famous for the later? During WW2 the British soldiers had a saying.
"The Yanks are over sexed, over paid and over here." but together we stopped a true evil. This thread has taught me two things: I have to install my own inline filter and I will have to figure out a way to modify the fuel rail so I can flush the injectors. By the way, I'm from Chicago, home of great pizza and we rival New Yorker's rudeness.

Why dint you say so. Nah New Yorker's are the politest people on earth, love their genuineness. Kindest place I ever lived.
Are you calling that horrible thick gut-busting thing made in a frying pan good pizza.
Take a poll, you will find no one with a 5.0 engine has had clogged fuel filter. But almost everyone, even with very low miles had injectors fail due to blockage.
The combustion in direct injection creates really fine soot (the same kind that laws have now been passed to put particulate filters on the exhaust). This fouls the injectors from inside the chamber and not through the fuel system.
But the carbon can be dissolved fairly easily by running several rounds of good fuel injector cleaner. (not that seafoam kerosene). Jahummer from the post above had very good results with CRC fuel injector cleaner. (or any brand that uses Techron). I use it regularly. Do a search on this forum for fuel injectors and cleaner.
