How-to DIY: Upgrade to new style fuel tank flange & filter
Most LR4 owners are aware of the TSB RCRIT-21V635-5779 from early 2022, for "Gasoline Fuel Tank Flange Assembly Cracking". The full PDF is at this link. What's not clear in the TSB is what the new parts look like. There have been some threads in the past (like this one) discussing confusion... -
How-To DIY: Replacing LR4 in-tank fuel pump
I recently did this job on our LR4, and I couldn't find any existing "How To" threads with detailed instructions on what's needed to do this job, or details about the pump itself. Figured I'd write it up before I forget how I did it. The original pump had 160kmi on it, details of the failure are... -
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... -

USA-spec 2010 LR4 with 5.0L V8 engine, 160kmi. No prior issues with fuel system. Truck died about 4 miles from our house after a cold start, about 4 minutes driving time. Would not restart, just cranked at normal speed, coughed and sputtered, but would not stay running. Towed home and now I'm... -

LR4 vacuum pump replacement info
After multiple failed attempts to externally seal the old pump on my 2010 LR4 (125kmi), I gave up and replaced it with the new style pump. The first re-seal attempt was at 121kmi, I applied replaced the gasket/seal to the block (it was fine), and applied a bead of sealant around the edge of the... -
Air compressor temperature - what is normal?
For those of you with a GAP IID tool, have you ever watched the live values for the air compressor (gallery pressure, compressor temperature, and motor temperature) as the compressor runs after starting the engine? Or, after lowering to access height and then raising to off-road height? My... -
Engine oil analysis results on 2010 LR4 V8
I haven't seen many (any?) people posting oil analysis results, and I'm guessing not many owners bother. Given the timing chain issues with the Jaguar AJ133 V8 engine in the 2010-2013 LR4, and the ongoing debate about appropriate oil ratings/certification, I was curious how the dealer oil was... -
Reflashing IPC ECU with GAP IIDTool ?
My GAP IID shows new software available for the instrument cluster (IPC), for Strategy and Calibration. Screenshot attached. However, when I run the "Reflash ECU" function, these items never update. I tried twice with the same results. Am I missing something? Do I have to download the updates... -
Will 2003-2005 RR wheels fit on LR4?
As a new LR4 owner, I'm looking for an extra set of wheels for snow tires. I'm also trying to keep the cost reasonable, and haven't seen many sets of LR4 wheels for sale at tolerable prices - I don't really want to pay $1k for wheels and another $1k for snows. I've found quite a few 2003-2005...
