You might have some crap in the fuel lines? I had to take my tank out and lift the sender unit, to drain it, but it wasn't enough. Took it out again and found that draining it still left a thin layer of grime/dirt around the tank that wasn't easy to see, until wiped it with a rag. So had to give it a thorough clean. Got to say that it wasn't easy to clean properly. Had to blow out the fuel lines as well. That got rid of the alarm/code/engine light. All from topping it up with about 1/4 tank of crap fuel.

You sure wouldn't expect that, there is obviously something weird going on there. Then again, your not the first person to have all sorts of issues after fitting a long range tank. Have heard of it before.

ps. With all hoses connected and engine off after it has been running, how many times can you work the plunger before it goes solid? Should be no more than about 2-3 times.

Yeah I get about 3 plunges max. Tweake is there a reason I should put the primer bulb by the tank? I got one from a boat builder joint. I was gunna just stick it inline on the piece of hose which goes from the hard line to the fuel filter as there is a space there plus I could use it to prime a new filter is the filter/primer ever actually shits itself and stops priming all together. Also apparently they work most effectively vertical so they you aren't solely relying on the spring valve as gravity works to close the one way valve as well as the spring?

I should also mention my fuel filter location is on the other side of the engine bay to stock so I no longer use the hard pipes which travel along the firewall. The filter is connected directly to the hard pipes on the chassis rail near the drivers feet

yes.
its very hard to suck fuel (and air) uphill. the fuel come down out of the tank fills the primer rather easily. also down at the bottom is an ideal place for a one way valve. this way you can disconnect the hoses at the filter and not have fuel run back to the tank.
downside its a bit of a pain for priming the pump as you can't see fuel coming out of the filter.

Okay sweet well ill put the primer in down just next to the tank before the start of the hard lines. Had the error code come up again today just idling up to a roundabout no engine issues at all, drove for about 10mins after to my destination and pulled the code sure enough the 0707 code was there again. When I fit the primer bulb I will purge the lines with an air compressor and pull the fuel filter out and check the inside of it through the bottom. When I ran the first tank of fuel through after the long range tank install it had a fair bit of gunk in there which was left over from me first flushing the tank with water then letting evaporust sit in the bottom of the tank as this was where most of the rust particles were. After all this I put 3x5L lots of diesel into the tank, tumbling it over and over and then draining before I fitted the tank.

I do have ecu talk. Is there something I can look at gauge wise to see if the fuel pump is on the way out? Like the icv%

Did some reading on the patrol forum. And saw ranges of 40-70 icv% was normal, local diesel specialist said lower end for d22s was 35% at hot idle. Mine at hot idle is 7 or 8% which ain't good and my cruising numbers at between 10 and 15% at say 2k revs cruising at 80 or 100kph. I will eliminate the fuel system by running the fuel line inlet and return directly in a clean container of diesel and see what the icv% is at hot idle then. I do suspect the pump however as I did the clear hose trick and saw no bubbles between the filter and the pump. It's just so strange that as it seems the pump is on the way out but there are no noticeable symptoms with the cars performance being pretty well normal?

Ran the pump direct from a container of diesel to rule out an air leak in the lines. The icv% was identical. At warm idle after the drive home it was better at 14% but still way out of spec. Car still runs and drives fine and no error codes even though on the drive home I saw the % drop to 4 or 5 multiple times.

Yeah I recall reading on Bailies Diesel that below 25 is considered a dead pump. 0707is the code to expect. That is an expensive fix, but cheaper than a new bus!

keep in mind what your reading the icv with. i think ecutalk reads it back to front, theres info in the patrol forum on that.
