The Turbosmart FPR800 is a motorsport-proven fuel pressure regulator capable of supporting fuel systems up to 800HP. Featuring a stainless steel valve and seat, a MILSPEC diaphragm, and industry-leading 1:1 fuel ratio control, the FPR800 is built to excel in the most demanding environments. The FPR800 is available in black, blue, red, or purple, allowing it to easily complement race builds or modified street cars.
It features two 1/8" NPT inlet ports, one 1/8" NPT return port and a 1/8" gauge port, base pressure adjustment from 30 to 90 PSI, a 1:1 ratio, and a premium MILSPEC diaphragm with a stainless steel valve and seat to support all fuel types, including E85, for engines with fuel systems up to 800 horsepower. The Turbosmart FPR features a non-directional bias toward the regulation, so regardless of where the fuel enters, it is regulated equally.

Before Ordering
〇 Regarding Import Consumption Tax
At the Shaftoya shopping site, we cover the import consumption tax incurred at the time of import, so there are no additional charges beyond the total amount paid at checkout.
〇Confirmation of Compatibility
Since our entire product database is based on North American vehicles (USDM), please confirm compatibility with Japanese vehicles (JDM) before placing an order. (Please feel free to contact us if you are unsure if a listed product is compatible with your vehicle. Our support team will investigate for you.)
If you place an order without confirming compatibility, we cannot accept returns due to incompatibility.
Please note that even if items are sorted by selecting the year, manufacturer, and model via the tabs on our top page, it does not necessarily guarantee that they will fit Japanese model vehicles without modification.
All products have 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 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 automated calculation. In such cases, we will contact you individually via email.
All products are generally shipped internationally from our US warehouse. Unlike domestic Japanese shipping, international shipping takes approximately 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. Please note that all products are transported by air freight; we do not use sea freight.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
The products we handle are basically all 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 calculation documents or similar paperwork for the Japanese inspection system. Therefore, all parts are sold for the purpose of "use on circuits, private property, or off-road," and installation and use are at your own risk.
○ Regarding Warranty
Please check the contents immediately upon arrival. Since all products are shipped internationally from outside Japan, there may be shipping damage to the packaging or the product itself. Please understand that we will only provide returns, refunds, or replacements for products with shipping damage, defective goods, or incorrect items if notified within 7 days of receipt. Furthermore, for products sold through us, all warranty-related support will be handled "exclusively through us." Please note that we do not provide support through other companies or distributors located within Japan.
