I ditched the mechanical fuel pump and am just using the Holley Blue now.I also made a ghetto sealed scoop pan for the air horn on the Demon.It can draw nothing but outside air now .I hope this stuff helps my Dart in Missouri in a few weeks.Its a 1/4 mile track and maybe some pressurised cooler air will help me into 11.70's .The scoop is a bit shorter than i would think is ideal ,but it looks cool and fits the 60's theme on this dart .More changes are coming ,and thanks again for the good advise ...
