05 Renault Kangoo Cuts Out?

They look like they have air in fuel pipes even when they dont best thing to do is remove airfilter housing and you will see 4 gold looking pipes going into engine with nuts on them, have van off and loosen them all off then jus nip them up lightly turn on van and one by one you loosen untill diesel spits out then tighten and repeat with the rest and that will get rid off any air in system
