Remove fuel line Citroen C6 / C5 2.7 HDI V6
 

Hi,

After the pre-delivery pressure in front of the diesel filter - should be between 0.5 - 0.6 bar - is only 0.38 bar with this Zitroenen crate, I am considering changing the first stage of the fuel lines from the pre-delivery pump to the first connection point, because in this part there is a connection flow / return with integrated pressure reducer (spare part 1525 PK with regulator).

This pressure reducing valve (regulator) reduces the pressure of the pre-feed pump, which delivers more than 2 bar to this reduced pressure.

Lt. Service documents for SID 201, the vehicle can no longer be started at a pre-delivery pressure of 0.3 and less.

There are 3 connections (flow / return / Eolys) on the pre-feed pump - provided there is no original additional heating.

The next connection point - forward / reverse under the vehicle - is not a problem.

After the feed pump, the lines first go down in a 90 degree bend - and there is the no longer visible connection flow / return with this integrated pressure reducing valve and its holder. This valve also has a connection to the atmosphere - like ??. - and only then in a further 90 degree bend to the front.

Has anyone already removed this pipe section?

If so - the tank has to be lowered - or is there a removable cover - or or ...?

Greetings Wolfgang
