AEM's 400LPH high flow fuel pumps were designed with high performance naturally aspirated and forced induction EFI vehicles in mind! They deliver the same high flow and reliable performance that AEM has become known for at very competitive price. Each pump is individually flow tested and guaranteed to flow 400+ LPH (106 GPH) at 40 PSI (13.5V), which on gasoline will support 1000+ horsepower!* The pumps also maintain their high flowrate even as system pressure increases flowing 330+ LPH at 70 PSI (13.5V) which will support approx. 870 HP* on gasoline! Please see the flow curves and current draw vs. fuel pressure graphs on the specs tab for more information. With their compact 39mm body (same size as Walbro 255), low amperage draw, 11mm inlets and 9mm barbed outlet's these fuel pumps were designed to replace the OEM fuel pump in many applications. The 50-1230 features a double barbed outlet that is ideal for 3/8-inch ID hose where the 50-1235 features a smooth barbed outlet that is compatible with 5/16-inch ID hose. Each pump includes a wiring harness, pre filter, end cap and rubber buffer sleeve.

  • Highest flow 39mm body fuel pump on the market. Each pump individually flowed and guaranteed to deliver 400+ LPH (40 PSI, 13.5V)
  • 100% Compatible with most fuels including: pump/race gasoline, ethanol (up to E100), methanol (up to M100)
  • Maintains very high flow even at boosted fuel pressures; 330+ LPH (70 PSI, 13.5V) (30 psi boost)
  • Both models feature a 9mm outlet barb with an 11mm inlet in-line with the outlet

Why Drivers Choose FAST of West Chester

  • I can't recommend this place enough. Being able to trust a shop in the performance world is big. The 2hr drive to get there, is worth knowing the job will be done right. Very happy to have found this shop, to
    support my builds going forward.

    Donald Wojnar

  • I recently had the pleasure of working with FAST of West Chester for some performance upgrades on my 2022 WRX, and the experience was nothing short of exceptional. I opted for a Borla S-Type exhaust and Cygnus Coilovers, and the team at FAST nailed the installation, fitment, and setup to a T.

    Adam Cranston

  • The team at FAST are excellence in every way. First, I consulted with Dave on mods for my HPDE track car. He listened and advised me on the best parts & mods to achieve my goals. He was patient & gave me space to research the options presented & worked with me through several changes before we built. Second, the build execution was flawless, proper heat shielding, bracing and poly everywhere. All components worked as advertised.

    Bryce Budd

  • This place has been my go to shop for all things Subaru. From simple service to performance parts and tuning, they have been top notch.

    William Brunell

  • Excellent shop. They installed a Cobb Stage 2 DP and Whiteline Sway bars and end links on my 2013 WRX. The work was done right and clean. The estimate was accurate. They were very knowledgeable, friendly and gave me the straight scoop on exactly what I was getting for the money
    and what I needed to get where I want to be with it. I'd recommend them
    to any car enthusiast.
