Do I need new software for the APR High Pressure Fuel Pump for EA839?

Yes. APR states that the ECU must be updated with compatible software for the High Pressure Fuel Pump for EA839 to work properly. The pump adds fuel volume, and the calibration must be set up to use that extra supply safely.

How much power does the APR 2.9T fuel pump add?

On a B9 2.9T running E85, APR measured 37 wheel horsepower and 50 lb-ft of wheel torque by adding the pump and moving from Stage 1 to Stage 1+ software. The gain depends on the fuel and calibration, since the pump supplies fuel rather than making power by itself.

Does the APR 3.0T HPFP raise fuel rail pressure?

Not as its main job. Despite the name, the upgrade raises the volume of fuel the pump can deliver at every engine speed by 37 percent. That extra volume keeps rail pressure from dropping when a larger turbo or ethanol blend asks for more fuel than the factory pump supplies.

Is the APR EA839 pump new or rebuilt?

Each unit starts from a new OEM pump with genuine Hitachi components. APR machines and fits its own bearing grade stainless plunger and barrel, a DLC coated plunger, a weight matched spring and a titanium retainer, then tests and breaks in every pump on a rig before shipping.

Which cars use the APR 2.9T and 3.0T fuel pump?

APR lists EA839 powered Audi S4, S5, SQ5, RS5, S6, S7, A6, A7, A8, Q7 and Q8 models, the Bentley Bentayga and Flying Spur, and the Porsche Cayenne, Macan and Panamera. Years vary by model, so check the full list or contact us with your VIN.

Description

APR High Pressure Fuel Pump for EA839 2.9T and 3.0T V6

The APR High Pressure Fuel Pump for EA839 engines raises the maximum volume of fuel the direct injection pump can deliver by 37 percent, for the 2.9T and 3.0T V6 in Audi, Porsche and Bentley models. Larger turbochargers and ethanol blends can outrun the factory pump, especially in the low and mid range, and the APR pump keeps rail pressure steady when fuel demand peaks. On a B9 2.9T running E85, APR measured 37 wheel horsepower and 50 lb-ft of wheel torque over Stage 1 by adding the pump with Stage 1+ software.

How APR Builds the Pump

APR bores out the pump to increase its displacement, using a plunger and barrel in heat treated, bearing grade stainless steel with a diamond like carbon coated plunger. Dimensional tolerances are held to 0.00004 inch and geometric tolerances to 0.00005 inch, a weight matched spring prevents float, and every pump is assembled in house, then tested and broken in on a rig before it ships. Each unit starts from a new OEM pump with genuine Hitachi components and uses a titanium retainer.

Additional Information

The Bulletproof Automotive website contains many thousands of products purchased in multiple different currencies. All of the prices are entered manually and accurately at the time of entry. Due to the consistently fluctuating international exchange rates, at times prices may not be able to be honored at their original intended rate. We apologize for any inconvenience this may cause, unfortunately our website is unable to compensate dynamically for what can at times be volatile changes in the cost of items due to currency values fluctuating, changes in prices from suppliers, changes in shipping and import duties, and other factors. Rest assured that any order you place on line will be at zero risk to you in this area. If in the event your order cannot be fulfilled at the original intended website price we will offer you a 100% refund, no questions asked. We will continue to do our best to maintain updated prices and we will always continue to offer our price match guarantees as well to ensure our prices are always the best for you. In short, prices may change without notice. It is always advised to give us a call prior to placing your order online to confirm availability and to confirm current pricing.

Shipping Policy

Items that are in stock in the US, either at Bulletproof’s warehouse or at a supplier’s warehouse, are generally delivered within 7-10 days. Special order items from overseas take considerably longer. As a courtesy Bulletproof offers delivery estimates to our customers which take into consideration manufacturer availability and shipping schedule. These estimates represent our best guess based on previous orders from the manufacturer and do not in any way imply a guaranteed delivery window. Many manufacturers work in a “just in time” inventory system and often take 2-20+ weeks to produce an item once an order is submitted. All deliverable items are then sent to our Japanese warehouse. Bulletproof ships a minimum of one full ocean freight container every month from Japan, oftentimes more than one a month. Ocean freight takes an average of 4 weeks. Typically it breaks down to one week in Japan for paperwork and customs, two weeks by boat and one week in US customs/clearance. Due to the wide number of variables between manufacturer and shipping schedules, delivery estimates are simply just that – estimates. We attempt to estimate conservatively and we usually deliver faster than our estimates suggest. It is not Bulletproof’s policy to guarantee delivery time of any special order item, this is impossible for us to do. By ordering you acknowledge that there is no required delivery ETA and an order may not be canceled or altered due to manufacturing or shipping delays, all ETA’s are provided as a best guess only. Please review the full Terms & Conditions here.

BP Pricing Difference

We do pricing a little differently on our JDM brands and we believe in making things simple and clear. No hidden fees or surcharges. Every price you see includes the shipping cost to our office in Los Angeles, California and all the associated taxes/duties/fees for bringing the products into the US. The only shipping you ever pay is from our facility in the US to your location. Be wary of resellers that don’t include the cost of international shipping in their pricing on JDM parts. While we believe we’ll always have the lowest all-in price on JDM products, we offer a price match guarantee for all authentic parts purchased from authorized dealers as well. For many international customers, it’s much more affordable to ship from the USA than from Japan directly, as the air freight and ocean freight costs are typically much less. However, for customers looking to ship directly from Japan outside of North America, or domestically in Japan, we can provide pricing specifically for that scenario. Please do not hesitate to contact us with any pricing questions or concerns. Please email us at sales@bulletproofautomotive.com with any inquiries.
