Megane 1.5 dci air bubbles in fuel line

[cankwas]

Hi all, I have a 05 1.5 dci which is having starting problems. I changed the glow plugs because they appeared to be dead. Starting issues still persist after new plugs. Cranking over in morning it starts then injector fault lights up. Looking in engine bay to the left clear pipes (fuel?) appear to have bubbles running through them. Could this be the cause? Any ideas on where to check for air ingress?
Thanks.

seems to be common on all diesel Meganes. Mines a 2006 1.9Dci 130. Same problem, and similar symptoms to yours. I'm about to change my holed pipe, so will update soon.

Changed my pipe this morning. The old pipe was chafed underneath, so couldn't be seen from above, but quite obvious when removed from the vehicle. Problem solved.
