Yes I did it, tank was in the front of car pushing back, 800 hp. Learned this from two guys running dragsters, running 600+ cu in chevys. That old test of how fast a fuel pump can fill a gallon can relates for rear tanks (overcoming g forces and selling high dollar fuel pumps). (Gas is heavy) where does all the junk in your car go when you nail it?
