DP Customs LB7 Fuel Distribution Block

The DP Customs LB7 Fuel Distribution Block is a one of a kind product designed for the LB7 Duramax fuel system. Whether you are pushing high horsepower at a competition level or want to make the most of your stock set up, this fuel block can be beneficial to you!   Until now, LB7s with aftermarket 3" y bridges could not fit a factory or aftermarket LB7 relief valves. Aftermarket 3" y bridge necks interfere with the banjo style reliefs forcing the end user to use a plug in the port instead. Running a plug instead of a relief can potentially damage the motor and injectors during rail pressure spikes. The DP Customs LB7 Fuel Distribution Block relocates the relief port to a vertical position and converts the system to utilize the 04.5-10 LLY/LBZ/LMM style instead. The 04.5-10 LLY/LBZ/LMM relief/plug is more compact, more affordable, and more readily available. When the relief valve pops off, the bleed off fuel flows through a -4 ORB style hole and can be routed back into the return line p
