There are two fuel filters. A "spin-on" and small opaque or clear "in-line" filter.

They should both be changed at the same time. Both can be purchased right here on "Fastlane".

1. The in-line filter is the easiest of the two (they both are easy) as all you have to do is loosen the little clamp on each end and remove the old one. Replace with a new one and reclamp.

2. The spin-on filter is located just behind the power steering fluid reservoir and is removed by loosening the large hex head on the top of it. Then just spin it off. It is not encased, and is FULL OF DIESEL so be careful not to spill all over. (voice of experience)
Do not overtighten as you need to "bleed" it later.
You can fill up the new filter with diesel before you put it on, but you can also just use the hand pump when you have finished replacing both of them.

Now unscrew the hand pump and pump until you do not see anymore bubbles coming out of the hex head on top of the larger spin-on filter.

Tighten hex head and you are done.
