While im saving for my ppg dogbox i figured Id add an inline pump as im close to maxing out my fuel system. I am currently running a walbro 450 rewired with 6an lines front to back. The injectors are fic high z 1650s. At 36 psi im almost at 100% duty cycle on e85. My question is with the inline pump do I basically cut the line downstream and splice in the pump inline? Then I would need to run a separate relay to the pump? Could I technically have the pump turn on when the ignition is on or should it be spliced in to the factory system so that it turns on when the cas is spinning?
