SBC-iD controller keeping car from starting??

[.jrmyrmx]

hello, i have a Blitz SBC-iD boost controller, recently its been cutting the fuel to my car somewhat randomly. if i jiggle the metal T that connects the throttle body pressure hose to the boost controller something clicks and the fuel will either quit circulating or will start circulating. why is it that nudging the vacuum hose cuts the power to the fuel pump? is it leaking? if so where can i get another little 3 splitter?

thanks.

That hose may be touching something else, I have the same boost controller and the car will start with it disconnected, even left one side of the 'T' of and it started fine, idle like shit but started.

i checked, if i wiggle the T thing carefully without moving anything else its still trips whatever is making the clicking noise. also i checked all the wires near the hose and theyre all solid. sometimes ill be driving and it will just stall and i can lean over and pull on the hose under the dash a bit and it will start up again. im not a very good mechanic but i have no idea why wiggling a rubber hose would trip an electrical switch.

can anyone at least tell me what is turning off and on? is there a switch that turns the fuel pump on and off that could somehow be triggered? i am trying to fix this problem fast since the car is my only source of transportation and i have to drive to school every morning.
