How-To DIY: Replacing LR4 in-tank fuel pump

[Land Rover Joe]

Looking for anyone's experience or insight with this fault and this problem - I think we have narrowed it down but am unsure.

I am going to look around for a new "Fuel Sensor and Hanger" and we shall try, try again.

Are there other things we should be looking for in and around there?

@gsxr 's thread on
https://www.landroverworld.org/thre...-fuel-system-low-pressure-sensor.45735/page-2

Comes to mind but I don't know what that "low pressure sensor" does and even he had great difficulty in understanding what it did (and he replaced it, if I understand correctly, with no change with his underlying issue).

Thanks for everyone's support and interest!

So to follow-up from my last post on this (#11) -

I am busted for not finding all the threads - answer to my question -

In his thread:

How-To DIY: Replacing LR4 fuel system low pressure sensor

While chasing a fuel system problem (details in this thread), one of the possible solutions was a faulty low-pressure sensor in the fuel supply pipes from the tank to the engine. Since a new sensor was ~$40 it seemed like it was worth a shot before dropping the fuel tank, which apparently...

And I had purchased my parts a while ago (photo below)...which I now realize are the older components (which are supposed to be replaced with the newer parts as cited in the Technical Bulletin).

Dropped fuel tank and then the old components pulled out attached. They were still working properly but I was going to go ahead and replace everything while the fuel tank was down.

Unfortunately, I still have to fix an issue with the fuel level measurements; for more, see that thread in

And yes - folks are still selling the old parts (I bought mine from Atlantic British) ~

That said, does anyone have any advice or bad experiences with the old components? Is there something I should be looking out for based upon the technical bulletin?
