HDi fault codes help please

[rd070707]

The clutch and tps codes clear but the low fuel pressure pump one won't clear, but the eml goes off when i clear the other two. The car idles pretty perfect though, I thought at one point I saw the needle move ever so slightly at idle but not exactly hunting.

although you are right about how it drives, it only really is dead when I use past half way on the throttle, before that its okay.

I will remove the spring today, was going to do it anyway.

and yeah the hiss is when I put my ear directly to the fuel filter housing, thats what i will be doing tomorrow is changing the filter and o ring etc.
