KEMSO 38mm Intank Fuel Pump 200LPH Upgrade - Lifetime Warranty

In this review the KEMSO 38mm intank fuel pump is examined for riders and DIY mechanics who need a reliable high-flow replacement. The bottom line: this pump is for anyone upgrading an OEM unit that only delivered about 60-80LPH and needs consistent higher flow and USA-based support. The reviewer found the pump delivers significantly more flow, retains OEM fitment for the 38mm body diameter application, and offers a serialized housing tied to a lifetime warranty, making it an attractive long-term replacement rather than a temporary fix.

Key Features

• High flow capacity: Supports up to 200LPH, providing stable fuel delivery for modified engines or accessories that demand more than the original 60-80LPH flow.
• OEM fitment: Designed to match the 38mm body diameter and install into the factory intank assembly without modification.
• Fuel compatibility: Built to run on gasoline or ethanol blends so it fits modern fuel choices and small engine needs.
• Bypass valve: The bypass valve is set at 125.8psi, higher than many originals, which helps maintain pressure under load and supports consistent performance.
• USA-based support: Technical and warranty support is provided by USA technicians, easing troubleshooting and returns for domestic buyers.
• Serialized lifetime warranty: Each pump body is serialized and covered by KEMSO's lifetime warranty, giving long-term peace of mind.

Who It's For

This pump is best for owners of ATVs, motorcycles, or other small vehicles who are replacing an underperforming OEM intank pump or upgrading to support tuning and higher power demands. It is especially useful where the original pump delivered only 60-80LPH and the vehicle experienced fuel starvation or surging under load.

Those who should look elsewhere include users who need a different body diameter or a pump rated for diesel applications, since this unit is specified for gasoline and ethanol. Also, if in-tank space or connector types differ from the 38mm OEM assembly, confirm fitment before purchase.

Pros & Cons

Pros

• Notable increase in flow versus typical OEM pumps, improving throttle response during high demand.
• OEM-style fitment for 38mm intank housings makes installation straightforward for many users.
• Lifetime warranty tied to a serialized body plus USA-based technical support simplifies service and replacements.
• Works with both gasoline and ethanol, providing fuel flexibility.

Cons

• Some users report mixed opinions on the included filter quality, so expect to inspect or replace the filter if you prefer a different element.
• The higher bypass setting at 125.8psi may not match every factory pressure spec, so verify system compatibility for very sensitive fuel systems.
