I completed the modification of the Ford fuel pump/sender:

The Ford pump has a crazy little pressure bypass in the line between the pump and bulkhead. Since this pump won't see any real pressure, I got rid of it and used a piece of fuel line. Then I cut the pump bracket and welded it back together at about 6" deep.
Then I cut the pick-up tube from my stock Mopar sender and welded it on to the Ford bracket at a decent angle. I wrapped the sender with a wet rag to protect it from excess heat during welding.
I am using the stock Ford check valve on the return.
When the install is complete I will have an access in the trunk floor to get at this thing. I have full swing on the float arm, but I will have to get used to keeping the fuel level higher, due to the in tank pump and no sump or baffles.

I've been thinking all along that initial startup would be with the big MAF and injectors and starter tune from SCT. The more I think about it though, there is an awful lot to learn by trying the system with a stock 4.9 tune, sensors and injectors. I've got a wide band and odds are this thing will run pretty rich out of the box. I'll get a bunch of fault code, but since I don't have a check engine light or scanner, out of sight out of mind.
So far, this build is dirt cheap, with the real expense on its way ie BA5000 MAF couple hondo, 60# injectors 300.00, tuning pay-cage 800.00 or so, and none of that is necessary to try it ala carte.
Wait, the tuning package is $800!? I'm seriously considering building a $278 Megasquirt II and buying the $67 8' wiring harness.

How much do you have in the ECU and electronics if you don't mind me asking?

SCT tuning packages. I'll use the one in the middle.
http://www.lasotaracing.com/MOPRP.html#anchor
ECU, all sensors, fuel rail 60.00
Fuel pumps, surge tank 35.00
Throttle body. 25.00
VSS. 40.00
Distributor, coil,ICM 20.00

When I first read about the EFI installs being done to slants, the only ones I saw we're MS. I got Intimidated by the idea of building a kit, studying a mega manual or two then adding more to control timing. Anyway I decided that my stubby sausages don't belong anywhere near the thinking parts of a computer.
That's why Reed's post about the Ford was so appealing. Ford seems to take their EEC R&D very seriously and Mustang and F150 guys are driving a chip burning and tuning industry, so I get the benefit of their experimentation, too. That left me looking at tweecer, Quartehorse and SCT. At this point, SCT is still the costliest option, but it writes directly on the Fords innards, provides data logging, and I don't think I'll need to learn binary code, morse code or any other kind of code.
With all that said, I admire all the work the guys here have done with EFI. I don't doubt for a minute that MS is a great system. I just settled on what I thought I would be comfortable with.

I have to put in a plug for the TWEECer here. I have been using it or about two years now to run my 89 Ford van that I swapped from a speed density 302 to a MAF 351. The TWEECER RT runs about $450 new (I got mine used on eBay) and provides real time data display, realtime data logging, realtime rewriting, five different program settings that you can switch on the fly. I haven't really had the time to sit down and learn all the finer points, but even I have been able to figure it out enough to get a decent tune on my motor. The Tweecer has numerous support websites and even a Yahoo group that the inventor of the Tweecer is an active member of. The TWEECER does require you to have a laptop to talk to the Tweecer and datalog and change stuff, but you can pick up a cheap laptop easy.

I am by no means a computer geek, but I have been able to learn how to tune things on my van and I am confident I can get a slant set up pretty quick. I like the Tweecer and will be getting another one (or possibly two) to do the EFI conversions on my brother's Duster and maybe his van.

A Ford 4.6 has bore centers similar to ours, so I took a set of fuel rails and cut the end bung off of each. Then I migged a 1/4" stainless pipe nipple between them in the supply to obtain our 2" spacing and a 1/8" SS nipple into the return. I pressure tested by placing #5 rubber stoppers (HomeDepot) into all the open holes and tie wiring them in place. I pressurized the Shrader valve and held it under water. Good to 75 psi.

Cost 12.00. Stock Ford regulator may work with boost ref and pump gas. Anybody have experience with boost referencing this regulator?

Although the bore centers are slightly off, there is plenty of wiggle room in the injector fitment to begin with. If it doesn't work, I'll do it again.

This is good news! Ill be doing this instead of custom fuel rail with 6 holes drilled and fingers crossed for sealing.

The Ford system was built for many years by Motorola in Seguin TX. Ford had supplier deals with Motorola dating back to the early years of car radios, 1930s. A decade or so ago when Motorola lost the Ford contract for engine controllers Motorola sold the automotive parts division. A German company named Continental owns the Seguin plant today, which still makes engine controllers. Using an OEM engine controller is a good idea as the quality of these systems is excellent and spares are cheap.
