Construction & Design

The AEM 320LPH fuel pump features a black plated steel exterior with laser etching for durability and corrosion resistance. Its compact 65mm diameter allows it to fit most in-tank applications without requiring extensive modifications. The offset inlet fitting (7.7mm ID, 11.0mm OD) and 8mm outlet hose clamp connection are designed for ease of installation and secure fuel line attachment.

Internally, the pump utilizes a single scroll ceramic turbine impeller, which provides efficient fuel flow while resisting wear from ethanol’s lower lubricity. The pump’s pressure relief valve activates at 80 PSI, protecting the fuel system from overpressure conditions. Electrical connectors use 6mm spade terminals for reliable power delivery and ease of wiring.

Installation & Fitment

This fuel pump kit is designed for universal in-tank mounting on high-performance vehicles, including both naturally aspirated and forced induction setups. Its 65mm diameter and offset inlet facilitate straightforward installation in most factory or aftermarket fuel tanks. The included wiring harness and pre-filter simplify the upgrade process, reducing installation time and ensuring proper fuel filtration.

While no specific vehicle fitment is required, it is essential to verify compatibility with your fuel tank dimensions and electrical system. Proper fuel hose diameter and system voltage will influence the pump’s flow capability and overall performance.
