How Much Is a Fuel Pump for a BMW 335i?

A replacement fuel pump for a BMW 335i typically costs between $250 and $900 for the part alone, with total installed cost at most repair shops ranging from about $600 to $1,600, depending on model year, whether it’s a high‑pressure or in‑tank pump, OEM vs aftermarket, and local labor rates. This article breaks down what you’re actually paying for, why prices vary so dramatically, and how to estimate a realistic budget for your specific 335i.

Why Fuel Pump Prices for the BMW 335i Vary So Much

The BMW 335i, especially the turbocharged models (E90/E92/E93 and later F30), uses a complex fuel system that can include both a low‑pressure in‑tank pump and a high‑pressure fuel pump (HPFP) on the engine. Each has a different price range, and BMW’s move from the early N54 engine to the N55 and then later updates also affects availability and cost.

High-Pressure vs. In-Tank Fuel Pumps: Knowing Which One You Need

High-Pressure Fuel Pump (HPFP)

The HPFP is the component mounted on the engine that pressurizes fuel for the direct‑injection system. On many 335i models, especially early N54 engines (around 2007–2010), the HPFP is a known weak point and is significantly more expensive than the in‑tank pump.

The following list outlines typical cost ranges for high‑pressure fuel pumps on a BMW 335i.

• OEM BMW HPFP (Dealer or Genuine Part Suppliers): Roughly $550 to $1,000 for the part alone, depending on model year and supplier.
• OEM-equivalent / reputable aftermarket HPFP: Approximately $350 to $700 for a quality non‑BMW‑branded pump.
• Remanufactured HPFPs: Often in the $250 to $500 range, but availability and reliability vary widely by rebuilder.
• Labor to replace HPFP: Typically 2–4 hours at independent shops, so around $250 to $600 in labor at common U.S. rates ($125–$150/hr in many metro areas).

Putting these figures together, the total installed cost for an HPFP replacement on a BMW 335i usually lands between roughly $700 and $1,600, depending on whether you choose OEM or aftermarket and whether you use a dealer or an independent shop.

Low-Pressure In-Tank Fuel Pump (Lift Pump)

The in‑tank pump (often called the low‑pressure or lift pump) is located in the fuel tank and supplies fuel to the HPFP. When people casually say “fuel pump,” they sometimes mean this component, which is usually less expensive than the HPFP.

The following list covers typical cost ranges for the in‑tank fuel pump on a BMW 335i.

• OEM BMW in-tank pump assembly: Commonly $300 to $550 for the full assembly, depending on the exact part number and chassis generation.
• Aftermarket in-tank pump (quality brands): Often in the $200 to $350 range for an assembly that meets or exceeds OEM specs.
• Budget or no‑name aftermarket pumps: Can be as low as $120 to $220, but quality and longevity are more uncertain.
• Labor to replace in-tank pump: Usually 1.5 to 3 hours, translating to about $180 to $450 at typical labor rates.

In practice, a complete in‑tank fuel pump replacement on a BMW 335i usually costs between about $450 and $1,000 installed, depending on parts selection and where the work is done.

Price Differences by Generation and Engine Type

Not every 335i uses the same pump, and model year can influence both price and availability. The main split is between the E‑series 335i (N54/N55 engines) and the later F30 335i (N55), with subtle changes in part numbers and supplier pricing.

The following list summarizes how model generation impacts fuel pump pricing.

• E90/E92/E93 335i (2007–2013, N54 and early N55):
  

  • HPFPs for early N54 cars are often on the higher end of the price range thanks to demand and their reputation for failure.
  • In‑tank pumps are widely available, including aftermarket options, which can keep part prices modest.

• F30 335i (2012–2015, N55):
  

  • HPFP issues are generally less common than on early N54s but part prices tend to be similar or slightly higher due to newer design and fewer cheap reman options.
  • In‑tank pumps remain moderately priced with good OEM‑equivalent offerings.

• Performance / tuned cars:
  

  • Owners running big turbo upgrades or ethanol blends sometimes step up to high‑flow or performance pumps, which can push parts cost above the typical ranges—often $800 to $1,500+ just for performance fuel system components.

These generational differences mean that two BMW 335i owners can see significantly different quotes, even if both are simply told they need a “fuel pump.”

Dealer vs. Independent Shop vs. DIY

Where you have the work done is almost as important as which pump you buy. Labor rates and parts markup can dramatically change your final bill.

The following list explains how different repair options affect fuel pump costs for a BMW 335i.

• BMW dealer service:
  

  • Most expensive option, but uses genuine BMW parts and factory procedures.
  • Labor rates often range from $180 to $250+ per hour in many markets.
  • Total HPFP replacement at a dealer can easily be in the $1,200 to $1,800 range, while in‑tank pump jobs might run $700 to $1,200.

• Independent BMW or European specialist:
  

  • Typically lower hourly rates (often $120 to $170/hr) and more flexible on parts choices.
  • Can install OEM, OEM‑equivalent, or customer‑supplied parts, within shop policy.
  • Common total ranges: $700 to $1,500 for HPFP; $450 to $900 for in‑tank pumps.

• DIY at home:
  

  • Pay only for parts and any special tools—no labor cost.
  • Realistic parts‑only cost: $250 to $900 depending on pump type and brand.
  • Requires good mechanical skills, safety precautions, and access to repair information or guides.

Choosing between these options usually comes down to budget, your comfort level with car repairs, and how much you value a dealer service history versus saving on both labor and parts.

How to Get an Accurate Quote for Your Specific 335i

Because there are multiple pump types, engine codes, and part revisions, the most accurate way to know what you’ll pay is to tie the quote to your exact vehicle and problem diagnosis rather than general averages.

The following list outlines the steps to obtain a precise fuel pump estimate for your BMW 335i.

1. Confirm your exact model details: Have your VIN, model year, body style (E90/E92/E93/F30), and engine (N54 or N55) ready.
2. Clarify which pump is failing: Ask your mechanic (or diagnostic report) whether the issue is with the HPFP, the in‑tank pump, or another part of the fuel system like pressure sensors or injectors.
3. Get multiple parts quotes:
   

   • Check with a BMW dealer parts counter for an OEM price.
   • Compare with reputable online BMW parts retailers for genuine and OEM‑equivalent options.
   • Review customer feedback on any aftermarket or reman pumps you consider.

4. Request itemized labor estimates:
   

   • Ask at least one dealer and one independent shop for a written quote that separates parts, labor hours, and shop fees.
   • Compare estimates for both pumps if there is any uncertainty about which one you’ll need.

5. Factor in related components:
   

   • In some cases, shops recommend replacing seals, gaskets, or filters at the same time.
   • For HPFP issues, additional diagnosis of injectors or fuel lines may add modest cost.

By following these steps, you can narrow the broad price ranges down to a realistic, shop‑specific figure for your exact 335i and avoid unpleasant surprises at checkout.

Typical Price Ranges at a Glance

While exact numbers depend on your car’s details and repair choices, it helps to have ballpark ranges in mind before talking to shops or ordering parts.

The list below summarizes the most common price bands for BMW 335i fuel pump replacement.

• High-Pressure Fuel Pump (HPFP):
  

  • Parts: typically $350 to $1,000
  • Installed (parts + labor): about $700 to $1,600

• Low-Pressure In-Tank Fuel Pump:
  

  • Parts: typically $200 to $550
  • Installed (parts + labor): about $450 to $1,000

• Performance or high-flow setups (tuned cars):
  

  • Parts alone can easily reach $800 to $1,500+ depending on the system.

Keeping these ranges in mind can help you quickly spot quotes that are unusually low (which may indicate questionable parts) or excessively high without clear justification.

Summary

For a BMW 335i, a replacement fuel pump generally costs $250 to $900 for the part and $600 to $1,600 installed, with the higher figures usually tied to the engine‑mounted high‑pressure pump rather than the in‑tank pump. Model year, engine type, OEM versus aftermarket parts, and whether you use a dealer or an independent shop all influence the final bill. To get a precise number for your car, confirm whether you need the HPFP or the in‑tank pump, gather VIN‑specific part prices, and obtain itemized quotes from at least one dealer and one independent BMW specialist.
