What does it do

When increasing power or switching to ethanol, fuel system capacity becomes critical very quickly. The AEM 50-1200 provides increased fuel flow to help maintain safe air-fuel ratios under heavy load, enabling more consistent performance and improved reliability.

The pump body matches the dimensions of Walbro GSS341 and GSS342 pumps, making it suitable for many direct upgrade applications. In many vehicles it can fit directly into the factory pump hanger, keeping the installation clean and cost effective.
