Usually all diesels need bleeding. I've never had a diesel that hasn't needed bleeding after fuel pump has been replaced.

my step dad ran a diesel mazda import thing, out of fuel and it was a self priming diesel so just put diesel in and restart it

Strange I've worked on a lot of new cars and all needed bleeding.

My dad's old Astra van needed bleeding which was 'self priming'.

well my understanding of a self priming diesel fuel pump is that it will suck the diesel throught the pipes straight to the engine without the need for you to fill the pipes with fuel first, to prime a diesel you squeeze a little black rubber thing to fill the pipes with diesel a self priming does it for you

It supposedly does that, but in my experience, it don't.

Your engine is designed to bleed itself. I think it's the regulator which helps to bleed air out of the system. I took my fuel filter out at the side of the road a few weeks ago and when i put it in it started more or less on the button. All air in the system was gone after about 10 miles. (bubble in my in-line filter dissapeared)

One of the simplest jobs to do too. :D

You do need to pull the fuse to the fuel pump then run the engie till it conks out prior to doing this, so I believe
If it ain't broke, fix it till it is
