are they essentialy the same? whats the difference between one for an LT1, vs. a mustang. vs. any other car?

as far as I know a 12:1 FMU is a 12:1 FMU. They have 1 in, 2 outs, and a vacuum port. They rise 12psi fuel per pound of positive pressure.

What differences can there be?

Don't get a 12:1. I think star runs 8:1 and people still run incredibly rich. If you want injectors bigger then stock then you pretty much have to buy another FMU or else do it right and get the fricken S-FMU the first time around :)

nope, star runs 12:1.

Yep, STAR kit uses a 12:1 disk, you would use the 8:1 if you had 30lb injectors.

can anyone help with what parts i need for the sfmu all i have is the unit itself no other hardware
tia:thumbsup

Hmm..Ok, what exactly do you have? What internal pieces? Do you have the internal diaphram, spring, spring keepers, any disk/rings? Are than any screws or anything in the 3 ports on the SFMU lid?? If you look into each port hole on the lid, you should see a adjustment screw or allen head screw in the "vacuum" and "boost" ports. The SFMU ships from the factory with the "boost" port plugged with a screw.

i just have the sfmu no parts came with it, yes it has the 2 allen keys in both the boost and vac ports and a screw in the bleed port. the disc that in it is blue from what i can see from the outside if that helps.... no other hardware was included. do i need to open this up too see what's inside. tia for any help

The blue you see is the diaphram. I would open it up to see whats inside. Once you open it up, it should include in order, from the SFMU lid top,down : Spring keeper, short dark spring OR longer silver spring, second spring keeper, diaphram, then disk, then the ring around the disk. If you got the largest disk in it (3.72"), then that disk uses NO ring around it. If you have all of this, then you can get the extra disks/rings from Vortech directly. I believe the whole disk kit is around 35 bucks. I also recomend to get the optional bleed valve too. This valve will go into the "bleed" port on the SFMU lid top. You just take out the screw, and then screw in the bleed valve.

do you get that bleed valve from vorteh too...
tia for the info bro

Yes, you can get it from Vortech, OR you can get it from HRC, as they both use the exact same bleed valve on their FPR's. I'm not sure who is cheaper, i think HRC is.

yeh I got a star kit and I'm running airtex inline pump and I'm running pig rich here.
