E320 CDi Replacing Diesel Fuel Lines

Just purchased 2001 W210 E320CDi. Have problem starting car after it has been parked on a slope etc, pump loosing suction due to air ingress Have noticed slight fuel weep on lift pump suction line at the plastic fitting on pump from filter. Have bought 3 replacement lines from Mercedes

Can anybody recommend an easy method to replace the 3 lines (filter to lift pump, lift pump to HP pump and spill line back to common rail) without major part removal. My hands are too large to get at the lines!!

Use a screwdrriver to push in the holding clip then lever the pipe off. Push the new pipe into place in a similar fashion.

Thanks Dieselman for your advise

Do you have to remove the pump to thread the line from lift pump outlet to HP pump inlet? Also what about the spill line, the bolt looks very dificult to remove with big hands!!
