Re: 4.0 Eb Fuel Filter
Just a hint for when you intend to remove the old filter, mate. Use TWO well fitting spanners to crack the unions at each end of the filter. They can freeze up and be buggers to undo. Use a backing spanner on the hexagon on the fuel filter body, and the other on the hexagon on the backnut on the fuel pipe itself. Apply steady pressure until they separate. Try very hard not to damage or bur the hex on the backnut. If you do, you may be stuck with replacing fuel lines!
And before you even start, make sure you have reduced the fuel pressure in the system to a safe level so that you don't gey sprayed with fuel while you're under the car. Not fun! Normal working pressure is around 200kPa, or 40 psi, so take care. To do this, there are a couple of ways. Probably the quickest is to locate the fuel pump access cover in the boot floor, remove the cover and then remove the electrical connection to the pump. Then crank the engine for 10 seconds to lower the fuel system pressure. Good luck
