2011-2014 LML DURAMAX FASS 165 GALLON PER HOUR LIFT PUMP
MODERATE TO EXTREME HP (600-900HP)
A FASS Fuel Systems can be a beneficial upgrade for your GM Duramax LML diesel engine, this is because your Duramax doesn’t come with a factory lift pump like other diesels. This requires your CP3 injection pump to pull your fuel under a vacuum, adding additional stress to your CP3 Pump and risk introduce additional air into your fuel. This is where a Titanium FASS Fuel Pump comes in to help.
