KEMSO 13501 Intank Fuel Pump 35mm UC-T35 - High Flow Upgrade

In this review of the KEMSO 13501 OEM replace intank fuel pump the bottom line is simple: it is for drivers who need a clear upgrade in flow and a lifetime-backed replacement option. The pump's ability to support up to 200LPH-compared with many originals rated at 60-80LPH-makes it an obvious choice for higher-demand engines or modernized fuel systems, and the serialized body with a lifetime warranty provides peace of mind for those prioritizing long-term support.

Key Features

• High flow capacity: The pump supports up to 200LPH, delivering substantially more flow for higher-performance or modified engines that need consistent fuel delivery.
• Compatibility with fuels: Designed for gasoline or ethanol, the pump can be used in vehicles running common motor fuels without immediate compatibility concerns.
• Improved bypass setting: The internal bypass valve is set at 125.8 psi, which is higher than many original units and helps maintain pressure under load for improved engine response.
• US-based support: Kemso provides customer support staffed by USA technicians, which simplifies troubleshooting and warranty interactions for buyers in the region.
• Serialized lifetime warranty: Each fuel pump body is serialized and covered by Kemso's lifetime warranty, offering long-term assurance against many failures.

Who It's For

The KEMSO 13501 is best for vehicle owners upgrading from a worn or low-flow in-tank pump, motorists who have added performance modifications that demand higher fuel volume, and anyone who values a lifetime warranty backed by US-based technical support. Mechanics doing routine replacements on compatible 35mm body pumps will also appreciate the straightforward swap if fitment aligns.

It is less well suited for those who need a guaranteed perfect fit for a very specific factory housing without modification; some buyers report mixed fitment results and may need minor adjustments. Buyers primarily concerned about long-term durability should weigh the warranty and support against reported early failures when deciding.

Pros & Cons

Pros

• Substantially higher flow than many stock pumps, supporting up to 200LPH for improved fueling.
• Designed to run on gasoline or ethanol, providing flexible fuel compatibility.
