156 2.4 jtd 2004 - knocking sound

Hi chaps,

Any help would be appreciated.

Developed a knocking noise which i think is coming from the aux belt area. Dropped it to my local garage and they are suggesting it is the fuel pump causing the noise.

Bottom end sounds fine, not overly smoking. Has done 130k so know new cam belt needs doing now but dont want to spend more than the car is starting to be worth.

The knocking increases with revs.

any clues helpful
