Hello, i have B18c1 with darton sleeves, 81mm wiseco, eagle rods. Bosch 1000 injectors.

I am planning to go around 600-700hp. I already have 1 intank walbro with stock fuel lines. What would be the best? To add one bosch inline fuel pump + the 1 walbro in tank and retain stock lines? Add another one walbro in tank and run stock lines or run bigger lines?

 

There is a thread under the Drag Racing section that has a lot of info about fuel setups, you might be able to find some info there.
