Diesel Engine Woes..calling On The Collective Knowledge

[maccavvy]

Hi guys.

 

I've got a 2010 2.4 tdci transit

Drives spot on . But got an issue only started a few weeks back, when I come to it after 5-6 hours stood the fuel filter is half empty. So I fill up manually refit and turn it over till it bleeds up and starts.

It started at being left over night now it's getting worse.

I've tried a different fuel filter and even a genuine one. Someone mentioned maybe cracked fuel filter housing so out a genuine new one on.

Got new injector leak back seals going on tomorrow.

 

Any ideas..I can see me going to a hire van and some big bills looming soon.

Blocked tank vent? Could be causing a vacuum in the tank and then it 'sucks back' once the pump is off?

I'll check it.may even leave the fuel cap off over night..

On the lorries this can happen when the return pipe comes detached in the tank

To narrow down the fault disconnect the return pipe at the common rail then plug the common rail and connect a bottle of deisle to return pipe if it drains away then there is a problem with the return circuit

I'll try that out over the weekend
