Hi all,

I am yet again chasing air leaks in my fuel lines on my W210 E300 turbodiesel, I have a feeling its the seal on the pre filter again so will carry on fault finding.

Anyway, I was just wondering if anyone had replaced the whole fueling setup to just have a single fuel filter going from the tank feed to the cutoff solinoid?

As far as I am aware the fuel pressure is only at around 1 bar rather than the usual 50psi found in petrol engines fuel systems as its just a case of moving fuel from the tank to the injection pump.

I know of the requirement to have clean fuel going into the pump owing to all of the intricate passages within the pump and injectors but was just thinking if I could get a single large filter instead.

Does anyone know the size of the fittings on the fuel cut off solenoid? I guess I could look into simply attaching fuel line over the OEM connector and use the OEM connector as an adaptor so to speak.

Ideally I would just want to have:

Fuel feed > large fuel filter > cut off solenoid > fuel injection pump > fuel return

Has anyone done anything like this at all? I am guessing there have been other setups when using WVO due to the need for larger filters? Tempted to go along with the Lotus philosophy of "simplify then add lightness".
