hey i need a little help figureing out what line goes to my BOV and what line goes to my FPR im not using an FMU im using bigger injectors...and the 7afte bible onli shows u the lines to use if ur using an FMU so help i need to kno what line goes to the BOV and what line goes to the FMU?

Any good vacuum source will do. I'm not sure about the 7afe, but you should be bale to tap from lines that go to the intake manifold. I thought you said you weren't running the FMU?

im not using an FMU im using bigger injectors so wait i can use any line from the intake manifold to connect it to the BOV?? i thought i needed the line from the fuel rail.

You need a line from a vacuum source. Why would you want fuel in your BOV? You can use any vacuum source really.

ok so i can use any line from my intake manifold on my BOV? cuz thts not what the 7afte bible saids.

this what it saids(For the FMU, install the line coming off the fuel rail on the passenger side. Remove that line, then install one new line from the FPR on the rail to the inlet part of your FMU then from the FMU to the outlet line for the gas. On top of the FMU is a little hose you'll "T" that in the manifold and onto the BOV. (Look at the picture for reference)

Dude the lines they are refering to for the FMU is for feeding it with fuel. The fmu is used for raising fuel pressure by the what ever pounds of boost your pushing. When they said tee off the BOV and FMU from the manifold, thats for vacuum. The FMU has three nipples. One on top for vac. One on the side for fuel and opne on the bottom for fuel. I forgot which one was in and out. The top is for vac just like the BOV the top nipple is for vac.

oh ok thankxs i was i little confuse thier so i can just take any line from the intake header and put it on the BOV....thanxs for the help.

dont take just any line i made that mistake and my ac didnt work right till i fixed it ok the source you want to tap into is on the back side of the intake manifold and its the second vaccum line from the right...the one all the way to the right is your idle up selinoid DO NOT USE THAT ONE

the second one from the passenger side or the second one from the drive side?

second from the drivers side
