340LPH High Performance Fuel Pump for 600 BHP Applications - Kemso

In this review the Kemso 340LPH high performance fuel pump is judged as a budget-friendly upgrade for drivers who need reliable flow for boosted or naturally aspirated engines; the single biggest reason to buy is its ability to support up to 600 BHP while keeping compatibility with gasoline or E85. The reviewer found the serialized body and lifetime warranty reassuring, and notes that Kemso offers USA-based technical support, which matters if you plan to run this pump in a spirited street car or a light track build.

Key Features

• High flow capacity: Supports up to 600 BHP in N/A, turbocharged, and supercharged applications, making it suitable for many performance builds.
• Fuel compatibility: Designed for gasoline or E85 so users can switch fuels without worrying about pump materials.
• Bypass valve setting: The bypass valve is set at 125.8 psi, higher than many similar 255LPH and 400/450LPH options, which helps maintain pressure under load.
• Serialized body: Each pump is serialized and qualifies for a lifetime warranty, giving long-term assurance to the owner.
• USA-based support: Kemso provides technical support from US technicians, which simplifies troubleshooting and warranty service.

Who It's For

This pump is a good fit for owners of high-output street cars or entry-level race builds who need a durable electric fuel pump that can handle up to 600 BHP and work with either gasoline or E85. It is particularly useful for those who value a manufacturer-backed lifetime warranty and local technical support.

Shoppers who require absolute OEM-level fitment certainty for a specific in-tank housing or who have seen reports of variable fit may want to verify compatibility before purchase; those running extreme, pro-level race engines should consult a fuel system specialist for higher-flow or staged solutions.
