first off,

DID the search! sooooo, this is what I'm gathering from my research

I'm running the a greddy kit at 7-8 psi, blue box isn't working for me

I have Greddy 310 injectors (not RC)
I currently have a vortech 12:1 fmu

Soo my questions are, Is an inline fuel pump necessary for this amount of boost?

and

8:1 seems to be the preferred disks while others argue that 10:1 and 6:1 are better for (insert reasoning) can anybody enlighten me on this?

like always, TIA

BTW, I will be posting a pic of my pump, I have no damn clue what goes where, if you guys could let me know that would be cool also

Yes, you need an inline pump with an FMU setup, and 12:1 seems pretty high for 310s.

 

yea go with 8:1 because 12:1 fmu disk is too high. Im running 8:1 with intank fuel pump and vafc. If you go 12:1 use an inline pump, otherwise if you go 8:1 its ok to use an intank cause fuel pressure will not be as high

are you running the blue box AND the 12:1 FMU? if so that could be the source of your problems

what's in or out? how do i wire it up?

 

No, I'm sorry,

I meant to say, I use to run the blue box but I took it out for the FMU,

so it's ok to use an INTANK fuel pump with 310's and 8:1???

 

NO! you need an inline fuel pump to be able to feed the FMU the pressure it needs to properly function.

INLINE WITH AN FMU

am using a 255 intank!
280 prelude injectors
12:1 vortec FMU

no problems whatsoever...

did i mention 9-10 psi on a stock LS!!!

How do you know that you are not detonating? Had your a/f ratio measured with a bideband o2 sensor NO! I promise you that if you get it measured you will be lean. YOU NEED high pressure to operate the FMU corectly. end of story. A intank 255 lph pump is not enough.

Ok Ok OK,

Think i'm going to run the bosch inline

Anybody want to let me know about this pump, it's minehttp://hometown.aol.com/pir8168/mickpic.JPG

what's inlet, what's outlet?

I need a relay huh?

Where am I suppose to find the fuel pump wire? the green and yellow one

 

run it throught the stock relay, for the stock pump.

Rob

 

I'm sorry if I sound like a noob, but

How do I run it through the stock relay?

 

also, would a 6:1 disk be pushing it??

 

Do the math and tell me what your max fuel pressure is, and what are the output ratings are for the 255lph pump?

Running Greddy Kit (no blue box) with Vortech FMU and Bosch inline pump on a B16a1. 6 psi for now..........
