AEM’s 400LPH High-Flow Fuel Pump is designed for high-performance naturally aspirated and forced-induction EFI vehicles! AEM offers the well-regarded high flow and reliable performance at a very competitive price. Each pump is individually flow-tested and guaranteed to flow 400+ LPH (106 GPH) at 40 PSI (13.5V), supporting over 1,000 horsepower when using gasoline!* The pump maintains high flow rates even as system pressure increases, flowing 330+ LPH at 70 PSI (13.5V) and supporting approximately 870 horsepower* when using gasoline! Please see the flow curve and current vs. fuel pressure graphs in the specifications tab for details. Featuring a compact 39mm body (the same size as the Walbro 255), low current draw, and an 11mm inlet and 9mm barbed outlet, these fuel pumps are designed to replace factory fuel pumps in many applications. The 50-1230 features a dual-barb outlet ideal for 3/8" ID hoses, while the 50-1235 features a smooth barb outlet compatible with 5/16" ID hoses. Each pump includes a wiring harness, pre-filter, end cap, and rubber buffer sleeve.


Before Ordering

〇Regarding Import Consumption Tax
At Shaft-ya Shopping Site, we pay the import consumption tax incurred at the time of import on your behalf, so there are no additional charges beyond the total amount paid at checkout.

Compatibility Check
As our entire product database is based on North American (USDM) vehicles, please confirm compatibility with Japanese (JDM) vehicles before ordering. (If you are unsure whether a listed product is compatible with your vehicle, please feel free to contact us. Our support team will be happy to look into it for you.)
If you place an order without confirming compatibility, we cannot accept returns due to incompatibility.
Please note that even if products are sorted by selecting the year, manufacturer, and vehicle model using the tabs on our top page, this does not necessarily mean they will fit Japanese model vehicles without modification.
All product information has been translated into Japanese using translation software. As there may be confusing expressions, please contact us before ordering if you have any questions.

○Regarding Shipping
Shipping costs are paid at the time of checkout. Shipping estimates are calculated automatically on the checkout page when you enter your shipping address. For large items such as body parts, there may occasionally be a significant discrepancy between the automatically calculated shipping cost and the actual shipping cost. In such cases, we will contact you individually via email.

In principle, all products are shipped internationally from our US warehouse. Unlike domestic shipping in Japan, international shipping takes approximately 7 to 14 days, so please allow sufficient time when ordering. If you are in a hurry, please contact us in advance to confirm delivery times. Note that all products are transported by air. We do not ship by sea freight.

○Regarding Compliance with Japanese Vehicle Inspection (Shaken)
Basically, all products we handle are designed and manufactured outside of Japan. Please note that they are not compliant with the "Japanese Vehicle Inspection System," and we are unable to provide strength study documents or similar for that purpose. Therefore, all parts are sold for the purpose of "use on circuits, private land, or off-road," and installation and use are at your own risk.

○Regarding Warranty
Please check the contents of your order immediately upon arrival. As all products are shipped internationally from outside Japan, there is a possibility that the shipping box or the product may sustain damage during transit. Please understand that for products with shipping damage, defective products, or items different from what was ordered, we will only provide returns, refunds, or replacement exchanges if you contact us within 7 days of receipt. Please note that for products sold through our company, all warranty-related matters will be handled "only through us." We do not provide support through other companies or distributors located within Japan.
