A FASS Fuel System will be a very beneficial upgrade for your GM Duramax diesel engine, this is because your Duramax doesn’t come with a factory lift pump like other diesels. This requires your CP3/CP4 injection pump to pull your fuel under a vacuum, adding additional stress to your CP3/CP4 Pump and risk introduce of additional air/vapor into your fuel injection system. This is where a Titanium Signature Series FASS Fuel System comes in to help.
