I bought a bunch of misc turbo mopar parts last year and one of the items was a Walbro 255 in line fuel pump. I am wanting run a fuel tank up front like Gary Donovan did in the K car and I have 2 questions. #1 The pump is suppose to be knew and when I shake it, it sounds like it has a small rattle. Is this normal? And #2, if it is normal will the pump be enough to run by itself without the intank pump and push 40% larger injectors.
