Do your original LB7 fuel injector lines have rust and corrosion build up where they meet the injector nuts? Are the sealing surfaces showing damage?

 

Replacing the fuel injector lines is highly recommended when changing the LB7 fuel injectors. The original lines can have rust and corrosion build up near the ends of the lines. Or worse, corrosion build up between the nut and line that cannot be seen that can break loose during assembly and fall into the injector inlet. These sources of contamination will cause problems to your new injectors. They can also damage the sealing surfaces which will cause a high pressure fuel leak into the engine oil. Don't risk your new injectors or engine with questionable fuel injector lines and buy a set today! 

 

Note: The line set is the same for each bank. This set comes with 4 high pressure injector lines to complete 1 bank of injectors. For both banks, please order 2 injector line sets.
