heres some **** i got out of a few things i read... 1 line, to 2 pumps will be almost 1/2 as cheap, but not as efficient. 2 lines, (1 going to each rail) will be very efficient, and if one of the pumps dies, you probably wont blow your motor as opposed to 1 line with both pumps on it. anyone care to add to, or correct me on anything if i am wrong or mistaken?

If you have one line going to each rail, they will still tap into the same FPR (unless you want to spend the cash to double up on FPR's and return lines as well). So the not blowing your motor if you lose a pump scenario isn't quite true. Everything else seems correct though.

If you have a fuel pressure gauge inside the car, you will know when one of your pumps are going bad. The fuel pressure will drop off, I v'e been running 2 denso pump for 2 1/2 years now. I'm also run two -6 line from the pumps, split into one -6 line up two the fuel rail.

i run two pumps with two -6 lines, one for each rail. lost a pump and pretty much knew it right away. i use one pressure guage on each line. i feel it prevented the loss of that motor. there are alot of ways to get the same result.
