Hi,
I didn't say it had a lift pump, I said it had a blockage in the small hole that feeds the Swirl Pot, from which the Fuel Pump, (wherever the fuck that actually is), draws fuel.
It's the fact that it's fine when 1/4 + tank full that gives it away, I've had it on several Vehicles now, some with In Tank Lift Pumps and some without, the first one was a 300TDI Disco I had years ago, and took me ages to figure out, now, with that symptom it's the first place I'd look
This /\ /\ /\
I just see someone says there is a hatch under the seat, if so that makes it even easier to check for shite in the swirl pot
These days with Lift and Transmission Jack I never bother removing seats / carpet etc to check, i just support the tank with Trans Jack and drop it down 10 mins usually, perhaps an extra half hour if a bolt breaks and needs a drill, or a metal pipe repair etc on an old rust bucket
