well, theres really 2 questions.

1, did you hook up that little plastic hose that goes next to the fuel line? what is it for? I figured its some sort of vent or something

2, when you get on it hard, does your pres. go down, or up? my bud's car stays at 60 most of the time, but when you get on it hard, it will go down to 50. He has a 9psi blower setup that makes 480 rwhp so this eng. may be reaching the limit of this pump as far as volume goes. any ideas or coments would be greatly appreciated.
