Jaguar S Type Fuel Pump Module Assemblys

Jaguar S Type Fuel pump module assemblys

Starting at low prices, AutoBuffy stocks multiple fuel pump module assemblies from top OE-quality brands. The fuel pump module assembly sits inside your fuel tank and delivers pressurized fuel to the engine while housing the fuel level sender. When it fails, your Jaguar S Type may not start or run reliably — ignoring it risks being stranded.

Signs your Jaguar S Type needs a new fuel pump module assembly

  • Engine cranks but won't start, or takes several attempts before firing
  • Engine stalls unexpectedly at highway speed or under hard acceleration
  • Noticeable loss of power or hesitation when merging or climbing grades
  • Whining or high-pitched humming noise from the fuel tank area
  • Fuel gauge reads incorrectly or swings erratically regardless of fuel level
  • Check engine light on with fuel pressure or fuel level sensor fault codes stored

Which fuel pump module assembly should you buy for your Jaguar S Type?

The most important decision is whether to buy an OE-equivalent direct-fit assembly or a universal-fit unit that requires transferring your existing sender float. Direct-fit assemblies include the pump, housing, float arm, fuel level sender, strainer, and wiring harness connector as a matched set, which simplifies installation and helps ensure accurate gauge readings. Grade and brand determine pressure output consistency and long-term durability.

OE-Equivalent Direct-Fit
Best for
Most drivers who want a straightforward swap with no fabrication
What you get
Complete matched assembly — pump, sender, float, strainer, and connector — calibrated to factory fuel pressure specs for your Jaguar S Type
Premium / OEM-Grade
Best for
High-mileage vehicles, tow rigs, or owners who want the closest-to-factory longevity
What you get
Higher-grade turbine pump internals, reinforced housing, extended warranty; often sourced from OEM-adjacent suppliers
Value / Economy Grade
Best for
Budget-conscious owners on vehicles with lower miles remaining or short-term fixes
What you get
Lower upfront cost; functional replacement that meets baseline pressure requirements, shorter typical warranty period
In-Tank High-Flow Upgrade
Best for
Modified engines, flex-fuel conversions, or forced-induction builds needing higher fuel volume
What you get
Pump rated for higher flow and pressure capacity; may require calibration of fuel pressure regulator or ECU tuning

Replacing the fuel pump module assembly on a Jaguar S Type

Replacing a fuel pump module assembly requires relieving fuel system pressure, disconnecting the battery, and either lowering the fuel tank or accessing the module through an in-cabin access panel if your Jaguar S Type has one. The locking ring securing the module to the tank must be turned with a specialty spanner tool to avoid damaging the tank or ring. Once the new module is seated and the ring is tightened to the manufacturer's recommended range — snug and secure without cracking the tank flange — reconnect the fuel lines, wiring harness, and battery before pressurizing the system and checking for leaks before starting the engine.

Frequently asked questions

How much does it cost to replace fuel pump module assemblies on a Jaguar S Type?
Parts start at low prices at AutoBuffy. The total cost depends on the grade you choose and whether you install it yourself or pay a shop. Professional labor typically adds one to three hours of shop time on top of the part cost, since the fuel tank must usually be lowered or dropped to access the module.
Can I drive my Jaguar S Type with a failing fuel pump module assembly?
You should not drive on a confirmed failing fuel pump module. A weakening pump delivers inconsistent fuel pressure, which can cause stalling in traffic or at highway speed — a serious safety risk. Continuing to drive can also overheat the pump by running it in a low-fuel tank, accelerating its failure.
How long does a fuel pump module assembly last on a Jaguar S Type?
Most fuel pump module assemblies last somewhere between 80,000 and 150,000 miles under normal conditions. Longevity is shortened by frequently running the tank near empty, using fuel with high ethanol content not rated for your pump, or contaminated fuel. Keeping at least a quarter tank helps the pump stay cooled by surrounding fuel.
Do I need to replace the whole module assembly or just the pump on my Jaguar S Type?
Replacing the complete module assembly is almost always the better choice. The sender, float arm, strainer, and pump wear at similar rates. Replacing only the bare pump inside an aging housing risks a second repair soon after, and the labor cost to access the tank is the same either way, making the full assembly the better value.
Will a bad fuel pump module assembly throw a check engine light on my Jaguar S Type?
Yes, it often will. A failing fuel pump can trigger low fuel pressure fault codes, and a failed fuel level sender inside the module commonly sets a sender circuit fault code. However, a mechanically weak pump does not always trigger a light early on — pressure drop symptoms may appear before any code is stored.
Is it safe to replace a fuel pump module assembly myself on a Jaguar S Type?
A DIY replacement is achievable for a mechanically experienced owner but requires strict safety precautions. Fuel vapor is highly flammable — work outdoors or in a well-ventilated area, disconnect the battery, relieve fuel system pressure before opening any lines, and have an appropriate fire extinguisher nearby. Incorrect reinstallation of the locking ring can cause fuel leaks.
