I was just wondering if anyone can tell me what that smaller port on this fuel system is for? I thought it might be for a type of fuel pressure, but I am not sure. It it smaller that the 2 fuel lines? My instructions are not very clear.

Thanks

That where you should place a boost signal.......

What sort of boost signal are you referring to?

Does that mean when it senses boost, it will up the fuel pressure?

hook into a vaccum line that connects to the stock vaccum line from your map sensor.


Your boost gauge, fmu and bov should be connected to this.

did you do the chex your fuel pressure before you took every thing off yet? you need to do that and then when its on the screw no the top alllows you to basicly tune the pump to your level of elivation i guess.


cutting the fuel line sucks blah lol

No, but I can do that in a few days perhaps...I can cut my fuel line & install a fuel pressure gauge to see what fuel pressure I am getting before installing this SF fuel system, then after installing it. With these two numbers, what should I be doing with it?

I assume that my fuel pressure gauge gets installed after the fuel pump, so it will be reading the higher pressure, so how do I go about tuning the pump for my elevation (and coldness of -20DegC)?

Another note is that I installed RSX injectors, should I put back in the stock ones before putting this turbo on? I asked Mike when he was making this fuel system to use a different compression ratio for these larger injectors, but I do not know if he did that or not? If not, there might be way too much fuel pressure for these larger injectore & spray too much fuel! But if he did & I put the stock ones back in, there might be too little fuel pressure! What fuel pressure should I expect?

Thanks for the help.

to be honest that drawing is really helpfull then a lot of instructions rofl.

you have to make sure when it idols the new fuel pump keeps the same presure as stock i guess.
