KEMSO 13501 Intank Fuel Pump 35mm Body - High Flow Replacement

In this review of the KEMSO 13501 intank fuel pump, the bottom line is simple: this is a high-flow OEM replacement for gasoline or ethanol applications aimed at drivers who need significantly more flow than typical stock units. It stands out because it supports up to 200LPH, well above the original 60-80LPH range, making it useful for vehicles with upgraded fuel demands or to restore pressure in older systems. The review focuses on fit, flow, and the practical value of a US-based support line and lifetime warranty for concerned installers.

Key Features

• High flow capacity: Supports up to 200LPH for stronger fuel delivery to upgraded engines or high-demand conditions.
• Compatibility: Designed for use with gasoline or ethanol so it fits a range of typical pump applications without fuel-type worries.
• Improved bypass valve: Bypass valve set at 125.8 psi, higher than original standards to help maintain pressure under load.
• Lifetime warranty: Serialized fuel pump body guarantees a lifetime warranty, offering long-term assurance for buyers.
• US-based support: Technical support is provided by USA technicians, which can speed troubleshooting and replacement decisions.

Who It's For

This pump is well suited to mechanics, performance hobbyists, and vehicle owners who need a robust replacement that exceeds stock flow rates. If a vehicle has upgraded injectors, turbo or supercharger modifications, or suffers low fuel pressure from an aging original pump, the KEMSO 13501 offers a straightforward swap to restore or increase flow.

It is less appropriate for people who require an exact OEM-spec, low-flow unit for stock-only restoration projects or for those who cannot confirm fitment with a 35mm body diameter intank assembly. Buyers who lack installation experience should consider professional fitting, since some customers noted fit and installation can be finicky.

Pros & Cons

Pros

• High output up to 200LPH provides a significant performance uplift over the original 60-80LPH range.
• Lifetime warranty with serialized body gives strong post-purchase protection and confidence.
• US-based technical support makes troubleshooting and warranty service more accessible.
• Works with gasoline and ethanol, giving flexibility for common fuel types.

Cons

• Some users reported mixed experiences with installation and fit, so careful verification of the 35mm body fitment is needed.
• The filter quality and longevity drew mixed feedback, suggesting filter inspection during installation.
