Yes but I was still surprised to find the tank pump priced around $1, 300, fortunately I sourced a second hand one with 12, 000km on it for just under $500. I'm hoping this will mark the end of my mechanical woes. Cape York beckons!Quote:

Ive been monitoring the fuel rail pressure with an Ultragauge at about 12000 psi at 110 kph on a flat road
The specification says the pump can develop 24000 psi, so Im concerned something is not right even though the RRS runs beautifully. Filters are clean and no faults are logged when I scan the PCM
Does anyone have measurements of actual rail pressures reading for TDV6 2.7, I can compare?
Lock it in 3rd and go like hell nailed to the boards up a big hill. Then you'll see > 1600bar.Quote:

As already mentioned, no faults? then no issue. The pressure will vary depending on load and an engine that develops such huge amounts of torque its sometime hard to make it work hard enough.Quote:

Yep, been there and done that. Greenmount hill has been my Italian tuneup drag since I started driving. I've always found being polite and not trying to bull**** (yes officer, I looked at the clock after I was alerted to your presence and indeed I was speeding. Sorry) resulted in a "take more care sir and have a nice day".Quote:

Nice steep hill and if you grab 3rd early enough you can get a good wind out before having to ease off at the top of the hill. I've seen indicated fuel pressures in excess of 1650 bar doing that. I've also done it with the van on the back to *really* blow the cobwebs out.
Gave the RRS a good flogging, locked in 3rd, like you suggest. Saw over 20,000 psi so happy with that. ThankyouQuote:

I know had the same issue with my Land Rover discovery 32.7 fuel pressure higher god top and knocking noise blowing black smoke card does not respond to acceleration. High-pressure fuel pump is already replaced. Injectors are already replaced. Fuel pump is already replaced. Fuel rail sensor already replaced. I have no idea what to do next. Any advice will really appreciate it.
The wiring to the fuel pressure sensor needs to be checked. The same DTC on a 4.4 TDV8/SDV8 can be caused by a bad connection in a connector in the wiring to the pressure sensor.
