DHD 700-125 Standard Fuel Block Upgrade Kit LLY LBZ LMM Duramax Diesel
DHD's standard fuel block upgrade kit eliminates the restrictive factory fuel test-port/fuel block located just rear of the alternator and replaces it with our high flow billet aluminum block. This standard kit will utilize the OEM low pressure fuel line hose (5/16) and come with everything to reroute the return and low pressure fuel supply hoses. Recommended on all high flow intake manifold upgrades.
This kit is a must for customers installing aftermarket Y-bridges and intake combinations.
