c 270 cdi fuel pipe checks?

[gert]

I have been recomended by a fellow site member to check that the return pipes of the fuel system are checked to make sure I have no leaks,as I have a strting problem.Is there an easy way to check the pipes and is there a particular area I should be looking at for problem,I have changed injectors ,rail seals,low pressure pump,still have problem starting when car is left over night,I have to turn over the engine for aprox 2 mins before it fires up,it,s then ok all day but next mourning it won,,t start
any ideas.

Have a look at the pipes to the high pressure pump on the front of the engine. Are yours the solid clear plastic type or the black rubber type?

My c270 had the same problem. Had all the plastic fuel pipes, fuel filter and high pressure pump changed. Now starts first time every time.
