I used the valve that is top, middle & rear of the engine - pretty close to the HPFP. It looks like a tyre valve, used an allen key to depress the centre pin.2005 2.7 TDV6 HSE, 160,000KM

Robbie,
Would air in the diesel line cause the engine to cut out?
Bob.
Hi Bob,
Ultimately lack of fuel would cause the engine to quit but the HP system should detect the pressure variation and command a shutdown to protect the HP pump; it relies on fuel for lubrication and is intolerant of cavitation.

D3 still driving just great, even giving it some harsh acceleration.
I have just ordered the Sealey pressure gauge from the UK, I will update with fuel pressure characteristics soon or if I have any other issues.2005 2.7 TDV6 HSE, 160,000KM

As a further update, Disco still driving great, idle a little rough at times.
Using the sealey gauge, pressure is 0.35bar, current draw is 3.3A
I get the impression my LPFP is not doing so well. Any thoughts?2005 2.7 TDV6 HSE, 160,000KM
Yes, both the current draw and pressure are low. Current: Discovery 3 06MY (55 reg) HSE Auto Zambezi Silver Allisport Fast Road Intercooler, V8 Brakes, Silicone IC Hoses, EGRs Blanked, Remapped, De-Cat pipe, FBHIC

I replaced my lpfp recently because of intermittant lack of power especially on the motorway however it did not fix my problem. Current draw on the old pump was 3.9A, the new one was 4.2A, so not much difference.
Now thinking it may be transmission as it sometimes hesitates to kick down thus causing the engine ecu to reduce power. Also vibration on hard acceleration in 3rd.
