P0087 on Jaguar by model: symptoms, diagnosis and fix
The 2004-2009 X350/X358 uses a saddle-shaped fuel tank straddling the driveshaft, with a lift pump on one side and a venturi jet pump transferring fuel from the other. When the jet pump or the lift pump module degrades, the engine side of the tank runs dry even though the gauge shows fuel: owners report momentary stutters or stalls at highway speed, hard starts in cold weather, and gauges that drop suddenly or read unreliably because the level senders are built into the non-serviceable pump modules. It affects the V8 and V6 petrol cars and the 2.7 diesel. The pump module is a sealed unit so the sender is replaced with the pump.
Common Symptoms
- Momentary stumble or stall at highway speed
- Extended cranking on cold starts
- Fuel gauge drops suddenly or reads wrong
- Stalling with a quarter tank showing
How to Fix
No recall. Check the fuel filter and fuel pressure first; if pressure drops under load or the fault follows fuel level, replace the in-tank pump module(s). Specialists recommend replacing both modules together since the sender units come with them. Aftermarket Bosch pump inserts are used by some owners to cut cost. Access is through the rear seat.

Frequently asked questions
What does P0087 mean on a Jaguar?
P0087 stands for "Fuel Rail/System Pressure - Too Low." This code means the fuel rail or fuel system pressure has dropped below the level the engine's computer expects. The computer monitors a fuel pressure sensor and has seen pressure fall too low, meaning the engine isn't getting enough fuel — especially noticeable under acceleration or load. This is most common on direct-injection and diesel systems that run very high pressures. Symptoms include hard starting, stalling, hesitation, lack of power, and possible limp mode. On Jaguar it is documented across 1 model: XJ.
What are the most common causes of P0087?
The most common causes of P0087 are: Clogged or dirty fuel filter, Weak or failing fuel pump (lift pump or high-pressure pump), Faulty fuel pressure regulator or control valve, Restricted or leaking fuel lines, Faulty fuel pressure sensor, Air in the fuel system or running low on fuel, Worn high-pressure pump (direct injection/diesel). The specific cause varies by vehicle.
How much does it cost to fix P0087 on a Jaguar?
Published repair estimates on Jaguar range from $400 to $1,500 depending on the model and root cause. If an issue mentions a recall or campaign, check your VIN with the manufacturer or NHTSA and confirm eligibility and coverage with a dealer.
