2011 DiD with 120,000k.
Couple of months ago started getting fuel starvation where fuel level in tank was under a 1/4, and only when under a 1/4 tank.
Had just changed my secondary CAV fuel filter...changed it again thinking it was a dodgy one.
Problem came back again...to the point the motor stopped on the Gateway.
Noticed that the CAV filter was dry of fuel....used the hand pump and got fuel up to the OEM and the CAV.
Got it started and limped it to the servo and filled up. Immediately no starvation issues.
Thought that it was heat related, as low fuel and with the oversupply return from the injector pump was heating the fuel up and problem happened, put cool fuel in and the problem goes away again.
SCV was the next idea....most prevalent on the forum...replaced with Roberts Hi-spec scv.
Exact scenario and problem happened again.
At this point in time, I had a bit of a "your an idiot" moment and remembered an issue I had on my FI KTM 990....where the pre-filter sock on the in tank pump got almost clogged and on low levels in the tank would starve the pump.
Theory being that the filter/gauze is mostly blocked with dirt etc, when the fuel is hot it makes the gauze material swell and become totally blocked. When cool fuel goes in, it shrinks the material a little and fuel starts flowing again.
So I get on the Russian parts/fiche site and low and behold there is an in tank filter.
So I order the part and the parts guy advised getting the rubber tank seal as well.
Access is through a plate under the right rear passenger seat, which then gives access to a little cubbyhole, that has another oblong plate that needs to be removed. (This one is an absolute pain to get out as you have to turn it 90 degrees in a very tight space)
Then you have access to the tank ring underneath that has the inlet and return pipes and pickup attatched.

This the OEM on the pickup next to the new one
Close up Old one left, New on right
This pic I have rubbed the black plastic end and you can see where it has wiped off a oily/dirty section
Closeup of crap in gauze
So anyways, this was the problem, all been good since then.
It appears to be a sludgy type residue...non metallic and not gritty.
Parts are
MR 556587 - $31.50 - Tank Pickup Filter
MN 106046 - $15.00 - Tank Pickup Gasket
Following show location on tank
The filter is the bit hanging off Part # 20
