Some pics of the fuel rail and regulator installed....
I think I need to redo the lines, but I'm not quite sure how I should do it. The ports on the regulator are AN-6, but the fuel lines are 7.5mm, and the only fittings I could get are for 3/8 line (9.5mm) and trying to fit 7.5mm hose on a 3/8 barbed fitting is not fun.

Can you reduce it to a AN-4 barbed fitting ? AN-6 to AN-4 reducing union > AN-4 barbed hose
fitting?<ul><li><a href="http://www.stockcarproducts.com/aqpindx.htm">http://www.stockcarproducts.com/aqpindx.htm</a</li></ul>

Where do you have your regulator mounted?
In hindsight, I don't like that short braided section, I don't think it will offer enough flex to allow for engine movement.

It is mounted in almost the same spot as yours.
The shop ended up cutting some of the hard fuel line to put the fittings on, IIRC they cut them back to where the 2 lines are mounted to the wall. This also allowed them to mount the regulator much higher on a metal mount so that the lines run staight to it. Once I get some pics of the setup I will have them posted, I will be going to the shop again tomorrow since today and tomorrow are my only days off.
BTW you might want to think about having the fuel feed line come in from the front and the closed end near the regulator, this way you will have more room for movement with the motor.

I was thinking about having the line do a right angle out of the fuel rail....
and then loop back to the regulator. This would allow for movement, and let me move the regulator.
I didn't want to cut the stock plastic lines until I knew it worked correctly. Now that it's working, I'll consider cutting the lines, but I'd rather not if I don't have to.

Hey John- If you dont mind..can u post how u put he ford maf in..cause i have one too that needs to
be put in. And as for the S-afc by apexi i have everything wired up except for the throttle position sensor. I can figure out what pin/wirecolor i should connect it too. The wiring diagram is confusing me a lil bit 
If you can please help me out i would greatly appreciate it. TIA

Just a Starting Point?
This calibration just duplicates the old curve, which maxed the 440 injectors by 5000 rpm and 18 psi?
Did you get any wide band data from that dyno run?
The blue curve is based on a package that included chip, 440's, and 3" tube with A4 maf core. Hopefully chip made some changes to the load tables.
For the ss table, seems like you would want to now create a new target curve, mabe 25% more flow per volt vs the blue curve, and use 25% larger injectors. This would give 5.5V to ecu, based on 4.5V from Ford MAF at 1200 flow. This would be about 400 hp. New FPR could be trimmed for quick global changes.
Since load tables will be depressed scaled down MAF output, should not make inj's any bigger than needed.

Yep...
No sense in making changes if I can't get the Ford MAF to act like the stock MAF.
I wasn't able to get any wideband readings on the dyno, but I have a LM-1 wideband unit arriving today.
I'm thinking I can slowly raise the fuel pressure, maybe 5%, then 10% and see how it runs. If there aren't any problems, then I'll look for larger injectors, and lower the pressure and start at 10%, 15%, etc...
