|DHD 700-155 Super High Flow 1/2" Fuel Block Upgrade Kit LLY LBZ LMM Duramax Diesel|
The DHD 700-155 Super High Flow Fuel Block Upgrade kit eliminates the restrictive factory fuel test-port/fuel block and replaces it with our high flow billet aluminum block. This kit is identical to our standard kit except the low pressure fuel supply hose is a larger diameter. This kit utilizes a fuel supply hose and also comes with our DHD stainless steel high flow CP3 fitting. Recommended on all high flow intake manifold upgrades or when running a modified stroker CP3 pump.
