KEMSO 340LPH High Performance Fuel Pump - Supports 600 BHP

In this review the KEMSO 340LPH High Performance Fuel Pump is examined for drivers who need reliable high-flow fuel delivery for modified engines. It is aimed at owners running naturally aspirated, turbocharged, or supercharged setups who want a pump that supports up to 600 BHP and is tuned for gasoline or E85. The single biggest reason to consider this pump is the combination of high flow capacity and a serialized body with a lifetime warranty backed by USA-based technical support, which makes it appealing to hobbyists and weekend racers who value support and long-term coverage.

Key Features

• High flow capacity: Supports up to 340 LPH and is specified to handle applications up to 600 BHP, giving headroom for many performance builds.
• Fuel compatibility: Designed for both gasoline and E85 so it suits owners converting to ethanol blends without needing a different unit.
• Bypass valve setting: The bypass valve is set at 125.8 psi which is higher than many comparable 255LPH and 400/450LPH pumps, helping maintain stable pressure under demanding conditions.
• Serialized lifetime warranty: Each pump has a serialized body that guarantees a lifetime warranty, offering long-term assurance for buyers.
• USA-based support: Technical support is provided by USA technicians, useful when troubleshooting installation or performance questions.

Who It's For

This pump is best for automotive enthusiasts upgrading fuel systems on street/strip cars, or for drivers running forced induction who need a reliable mid-high flow pump. It is also suitable for daily drivers converted to E85 that require dependable fuel delivery and want manufacturer support and warranty coverage.

Those who should look elsewhere include owners of low-power stock engines who do not need 340 LPH flow, or anyone prioritizing class-leading longevity over a lower entry price; some customers have reported durability concerns, so buyers seeking a decades-old proven OEM design may prefer an alternative.

Pros & Cons
