SF's fuel management, need some install help
i'm getting ready to install my kit real soon, i know how everything goes except the fuel system. i read the instructions, re-read the DIY, and searched but couldnt find anything to help me out. my main questions are what lines go where from the fuel pump? heres a pic
and what wires are supposed to connect to the other end of it? ^^^
i read there are 3 wires that i'm supposed to connect but all i have was this but it has 4 wires, 1 blue, 1 black and 2 reds. so red is for the power source, black is for the ground, i'm guessing blue is to the pump, but whats the other red for?
and if these connect to the pump, i read there was supposed to be a green wire that connects to the ignition, could that be the other red wire? cuz these were all the wires i got with my kit.
my last question is what exactly connects to this 3 way split? the pic in the DIY was a little fuzzy and all i could make out was the vaccum line goes in one side.
these are probably easy questions with simple answers but like i said, these are the only things that make me scratch my head when installing the kit, and the only way i'll understand it better is if i install it myself instead of a shop, plus i dont want to keep forking out cash if something should go wrong. so if you guys could sort these things out for me so i can understand it better, i'd appreciate it. and if you have any pics of what all this stuff looks like installed so i (and maybe someone else who might need to know) can tell where the lines go and what they connect to, that would also be greatly appreciated. thanks for the help!!

I don't even have the SF fuel system and I can tell you how it connects - very top of FMU is the tubing for the vaccum line. This is what controls the pressure of the diaphragm in the FMU.
The two points on the very right of the pump are for the power and ground wire. Not sure where they hook up with relation to the pump, but that's what they are for.
The two points on the very left, towards the bottom of the picture are your fuel inlet (from the tank), and your fuel outlet (to the fuel rail). Again, as I don't have an SF kit I'm not sure which is which.....Why don't you call SF and ask them? (not trying to be an @ss) Or, do they not answer their phone?

he is right...fuel in is the top fittin all the way to the left of the setup, and fuel out on the bottom...use your existin lines to connect is to the fuel setup...just cut the existin line in the middel and stick the piece off of the firewall in the fuel in, and the piece that is still attached to the fuel rail to the fuel out....as for the fmu...you attach a vaccume line to it...and the line will come off of that littlw white fitting that has all the nipples on it(the vaccume t)....it will connect to the vaccume line right behind the throttle body...you have to look for it...there is a good pic of it in the instructions in this forum....as for the fuse...the blue wire is your signal wire...connect that to any fuse that will come on when you turn your key one click..in the accessorie position...the black is your ground...one of the red wires with run to the fuel pump, and the other will run to a constant power.....it is also explained in the instuctions pretty good...let me know if you need any other help

t fitting should be ... VAC OUT , FUEL, BOV, BOOST GAUGE, VAC IN. If u dont have a boost gauge.. well get ONE. U need it.

so a line off the T fitting goes back to the fuel system? i thought the line on the side of the T fitting went to the fuel system?

i dont understand what u just said so im gonna repeat what i said. U HAVE 5 HOLES ON THE T FITTING.
ONE IS VAC LINE IN.
TWO IS TO THE TOP OF THE PFM (FUEL) ,
THREE IS TO THE BLOW OFF VALVE,
FOUR IS BOOST GAUGE
AND THE LAST IS THE OTHER SIDE OF THE VAC LINE YOU JUST TAPPED TO MAKE THIS ALL HAPPEN.
they dont need to be in this order, but IMO alteast the vac in and out need to be on the sides.
lol just hit me up on aim for ne thing else

Rep Power: 401 lol, ok this is my last dumb question, i swear! where does the vacumme in and vaccum out connect to? am i cutting into a existing line or is it the line that came with my kit attached to the T fitting?
cutting into an existing line from the back of the intake manifold to the sensor next to the throttle cable, if u look u can actually see it going under the throttle wire... cut into it after that.
ONE SIDE IS IN
ONE side is out
if u want ill take a pic tomorrow of mine and point it out installed.-
