Audi FSI Upgrade Your New Pump





Send us your "new" Audi high pressure fuel pump 
We will install internals, run it on the fuel pump tester, and return it to you. in a 24 to 48 hour turnaround time.

The HPFP Upgrade high pressure fuel pump increases the volume of fuel from stock by over 40%. To achieve this we modifying some key internal parts within the pump. Changing these components requires precision machining, enlargement of the pump and piston, and precision measuring components. Using inferior components on this critical part can lead to many problems. We only use certified H13 tool steel for our pumps, the final finish of the sleeve to piston surface is measured in RA then a final check is done in RZ (mirror like finish). This process allows for final fitment that goes to the .000005 of an inch. All our pump internals are nitride treated then cooled in a nitrogen vacuum chamber. This has been proven to give the best material treatment available for the H13 tool steel and the process is certified to meet the specifications for the high pressure pump internals. All parts are then hand fit (with protective gloves) and measured with air gauges to verify you are getting "matched" sets with every pump or pump internal.

Gen X seal, (patent pending) our fuel pumps have a second seal that keeps fuel from entering into the oil.  This is a common problem when you install  "internals" into your fuel pump.  Fuel contaimination in the oiling system can cause engine damage or ruin the cam pump lobe (loss of lubricity).  We are the only company that utilizes the OEM seal then installs another seal for oil control/fuel control.  This is an exclusive design that is a must have for high RPM operation or higher commanded fuel pressures (over 140 bar) in custom tunes.  It is the first control seal that works in conjunction with the OEM seal and is designed to work on stock or highly modified fuel systems/engines.

The HPFP Upgrade fuel pump tester is a key element in pump production process. With this fuel pump tester we can perform several tests to verify pump operational parameters:

  • Peak Flow vs RPM
  • Peak Pressure vs RPM
  • Chart RPM and pressure curves
  • Chart RPM and flow curves
  • Minimum operational pressure
  • Pump solenoid operation
  • Pump seals are good
  • Fuel temperature at high pressure discharge point
  • Low pressure feed pump psi

 

 

 

The tester allows for critical break in of the new pump, performance test to be ran and ensures a lifetime of worry free miles for any HPFP Upgrade pump that we offer. We are the only company that offers all the above items with every pump assembly. Some applications will need to be tuned for the higher output of the HPFP Upgrade, talk with your tuner about what will best meet the needs of your build. HPFP Upgrade has been building and testing high pressure pumps since 2008, we have accumulated 100's of thousands of miles on the road and 1000's of hours on the pump tester verifying that you are getting the quality and products that our customers demand. Take a look at the options we have for your vehicle application and buy with confidence in knowing that you are getting the best and tested high pressure pump on the market! All pumps come with a five year warranty after the date of purchase, or lifetime of the original owner.

Stage 1:

Audi 2.0T FSI High Pressure Fuel Pumps are brand new OEM stock, we replace the piston and sleeve in a clean room, run them on the HPFP Upgrade pump test stand, send out run sheet verifying proper pump operation.

Stage 2:

Audi 2.0T FSI High Pressure Fuel Pumps are brand new OEM stock, we replace the piston and sleeve, modify the factory feed supply, and machine the discharge check valve, assemble in a clean room, run them on the HPFP Upgrade pump test stand, send out run sheet verifying proper pump operation. The S2 pumps support an additional 18 to 22% flow over the standard high pressure pump upgrade.

This option is for new pumps only, we cannot upgrade used or low mileage pumps at this time.
