Alpha AMG45 Series High Pressure Fuel Pump for 2013-2019 Mercedes-Benz CLA 45, GLA45 and A45 AMG M133 2.0L

Introducing the Mercedes-Benz A45 AMG M133 2.0T Series High Pressure Fuel Pump Kit! This pump is CFD-Optimized, E-85 compatible, all stainless steel, laser welded construction, and is capable of flowing over 36% more fuel than the stock unit! It’s simple, if you want to make more power you are going to need more fuel. Note: An ECU recalibration is necessary for the fuel pump to function correctly. Engine damage can occur if no ECU tuning is done.

This pump features high quality all stainless steel construction. Use of the laser welding process insures that any potential leaks are non existent. The pump comes complete with direct fit hardware kit and plastic flange alignment tool. Like all Alpha products construction and performance are of the highest measure.

The Mercedes-Benz m133 HPFP pumps come ready for a quick bolt-on upgrade, and use all OEM type fuel fittings and electrical connectors.
