When upgrading fuel injectors or in-tank fuel pumps, an upgraded fuel pressure regulator (FPR) is often required. An FPR maintains a stable 1:1 pressure between the fuel pump and the fuel rail itself, supplied by the fuel pump, so that the fuel injectors can pulse accurately during each cycle of the combustion process. Fine-tuning fuel rail pressure is critical for high-horsepower engines, so a quality FPR is a must if you are planning an extreme build. Turbosmart offers four capacity options in its line of high-performance adjustable fuel pressure regulators for fuel systems designed to support up to 3,000 horsepower. All Turbosmart adjustable fuel pressure regulators feature common AN or NPT inlet and outlet fitting sizes, provision for an integrated fuel pressure gauge, and compatibility with many vehicle-specific mounting kits.

Before Ordering
〇 Regarding Import Consumption Tax
At Shaftoya 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.
〇 Compatibility Confirmation
Our entire product database is based on North American vehicles (USDM), so please confirm whether the product can be installed on Japanese vehicles (JDM) before ordering. (If you are unsure whether the listed product is compatible with your vehicle, please feel free to contact us. Our support team will check for you.)
If you order without verifying 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, it 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 automatically calculated when you enter your shipping address on the checkout page. For large items such as body parts, the actual shipping cost may occasionally differ significantly from the amount automatically calculated. In such cases, we will contact you individually by email.
Basically, all products are shipped internationally from our US warehouse. Unlike domestic shipping in Japan, international shipping takes about 7 to 14 days, so please order with time to spare. If you are in a hurry, please contact us in advance to confirm delivery times. All products are transported by air. They are not shipped by sea freight.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
Basically, all products we handle are designed and manufactured outside of Japan. Please note that they are not adapted to the "Japanese vehicle inspection system," and we cannot provide strength evaluation documents or similar paperwork for the Japanese vehicle inspection system. Therefore, all parts are sold for the purpose of "use on circuits, private property, or off-public roads," and installation and use are at your own risk.
○ Regarding Warranty
Please check the contents immediately upon arrival. As all products are shipped internationally from outside Japan, there may be shipping damage to the packaging box or the product itself. Please understand that we will only provide returns, refunds, or replacement exchanges for items with shipping damage, defective products, or incorrect items if you contact us within 7 days of receipt. Furthermore, for products sold through us, warranty support will be provided "only through us." Please note that we do not provide support through other companies or distributors located in Japan.
