DHD 700-012 LB7 Duramax High Pressure Fuel Line Kit

Skip the dealer prices and replace your damaged, rusty high pressure injector lines with this OE supplier replacement from DHD.

Our industry resources provide us excellent opportunities to bring you high quality products at industry leading pricing. These lines will fit like OE, seal like OE and last like OE without the OE price tag.

Unlike the Amazon and Ebay competition, our lines are tested to meet J1958 SAE standards. They must endure 30,000psi without breakage or leakage. The best part is we use the parts we sell! These lines are currently on multiple 1000HP trucks with rail pressures reaching near 30,000psi.
