He isn't. He says no fuel comes out at the bleed screw on the filter head, despite several attempts.
Fuel pump not working.

I’ve twin tanks on mine with separate valves , the passenger tank is empty, I managed to turn slightly the lever on empty tank and it ran rough and would not rev , when I noticed and closed the valve the filter must have been about empty I assumed it was easier for the pump to pull in air than diesel

He may have got a mouthful of air and diesel I meant to say
As pump just been overhauled shouldn’t think it would split straight away
Putting a gravity feed to pump would prove pump ok if it primes and then prob with sucking air in

With a single tank, and the end of the pipe under the level of diesel in the tank, it should only pull in diesel, unless there is a crack in the pipe somewhere, in which case it will pull in air.
No experience of twin tanks, but I have bled and started dozens of Perkins engines. In Land Rovers, Tractors, Boats, Generators, etc.

Missed the bit where he said the lift pump had been overhauled. In that case, I can only imagine he hasn't pumped it enough, or the lift pump is on the cam. I just don't see how you can get a problem with those, they are pretty simple.
Gravity feed from a can or similar is a good idea.

Okay gents after an extremely cold, windy and stressful evening. I rebuilt the lift pump. Turns out the pump mechanism wasn't engaging and therefore not creating a vaccum. After reconnecting everything ( sigh ) there is now fuel getting to the filter. Feels like there is a lot of pressure and diesel is bubbling out of the top of the brass instrument i pictured. Ive cracked the injectors and turned the engine over and not diesel or bubbling is coming from injectors. Whats next ? Sorry if i sound like such a novice all my engine knowledge so far is petrol carbs. First time learning diesel

Very similar set up to standard Land Rover, except the Injector Pump is horizontal, not upright.
Lift pump is exactly the same, little round one, driven by a cam on the camshaft, hand pump underneath.

When you are sure there is clear fuel coming from the bleed screw on the filter head, tighten the screw. Then leave it for a bit, come back, and loosen the screw, and pump again on hand primer. There will be a lot of air in the system if you have rebuilt it.
Then, when you are sure the filter is full of clean fuel, no air, look at the top of the governor housing on the injection pump, there will be a small bleed screw. Loosen it, and pump again on the hand pump, until clear fuel emerges from the screw. Put a bucket underneath while all this is going on, you may need to pump quite a bit of fuel through.
When you are sure the injection pump is full of fuel, tighten the bleed screw on the injector pump.
Get someone to sit in the vehicle, and turn the engine over. While they do this, loosen an injector pipe at the injector end. When you see drips of fuel, tighten the pipe. Engine will start.

That’s thanks enough, we all need a bit of help sometimes, glad you have sorted it, I’ve had mine maybe 15 years and still learning , you can crack on with the welding now

Not a problem. Glad you got it started.
When you have been doing something all your life, it isn't difficult to explain it to someone else.
