pull the white plastic fitting out of the fuel filter, fill the filter with diesel and refit the white plastic fitting.

The bubbles will now clear.

If you have cracked the bottom plastic water drain, or the filter is clogged it may be allowing air into the system, it usually a sign of an old filter. Open it up and have a look see, filters are cheap and easy to replace,

*Don't forget to have a full fuel filter, I mean go throughly over this procedure, or you will ge air lock*

I'm guessing fuel filter is clogged because there are only bubles when you rev it.
A vacuum gauge or switch attached tot he fuel line would let you know the filter was getting clogged (or if that's the problem) way before this happens.

Im going to change the filter anyway, to be sure I think.....maybe the valve on top of it too.

Usually a fuel filter change will do the trick.Also check the line clamps,and make sure they are tight.

Yes, changing fuel filter removed the air bubbles!! but I did have a small leak om my pump too.
It made a BIG difference in how car drives!!!! belive me!
