300TD (124) Air in fuel lines - where's it getting in?

[Timster]

Hi.

I can see air in the fuel pipes, both entering and exiting the pump. This is affecting performance significally!

Any suggestions as to where it's getting in?

Cheers.

do a search for air in fuel lines... lots of info and fixes on here.

most likely is the oring seals need replacing on the pipes and/or the main in/out rubber pipes are perished at the ends. Fit new 10mm piping.
