Starting our first 5.3 swap into 98 v6 mustang. Was just wondering how much fuel we need to make say 700 rwhp? Will be going with a TC78 and are trying to decide 60 or 80 lbs injectors. The car currently has a 310 lph Focus pump and are planning to add a second pump. Are the stock fuel lines going to be adequate?

What type of fuel? Pump gas or E85? I would do 80s either way. I dont think stock lines are gonna handle that kind of power in a v6 car.

My thought is the the lines are the same size in 03-04 Cobra. This will be a pump gas setup because there is only one station with E85 within miles. I also have a water/meth kit to add to the mix if needed, but would rather take a "set it and forget it" approach to the tune. I also have no issue with running a 3/8 feed line and using the factory feed for a return if need be.
