Ok, so now a update.
I believe I have all the parts needed to get the car started with exception of a battery.
Tanks Inc ~ 1967-69 Plymouth Barracuda EFI Fuel Tank
Tanks Inc ~ GPA-2 Fuel Pump 58psi / 190 Liters Per Hour
Tanks Inc ~ Fuel Sending Unit
Tanks Inc ~ Fuel Line and AN fittings
Tanks Inc ~ Fuel Tank Straps
Tanks Inc ~ Fuel Tank strap rubber liner
American Powertrain ~ HydroMax Clutch master cyl and brackets
Summit Racing ~ Crown Clutch and Internal Slave Cyl
Summit Racing ~ Starter
Summit Racing ~ Distributor
Quadratec ~ Crank Position Sensor
Quadratec ~ Spark Plug Wires
As these parts start showing up in the next 2 weeks, I will get a order from Napa Auto Parts for the O2 Sensor and Spark Plugs.
I have already bought the correct flywheel, I will need to confirm I own the Bolts. I keep a new set on hand as my 1992 Wrangler has a AX-15 5 sp. If not, I will be buying bolts as well.
The fuel pressure issue has been resolved. The pump is a 58psi pump, and the fuel managment is looking for 48psi. I bought the above tank and pump so I knew I had a return line option which would work. In 1999, the fuel system pressure is controlled by the ECU which tells the Pump. There is no return line. In my setup, the fuel pump is ON or OFF by a relay. The earlier HO fuel rail such as found on my 1992 Jeep Wrangler has a vacuum operated return regulator. Best yet, the Jeep uses standard 3/8 quick disconnect fittings. Which came with the Tanks Inc kit. This will keep the pump running and cooled as fuel flows thru it.
I can not wait to get the exhaust installed. FlowMaster dual chamber 2.5in single in / 2.25in dual out and FlowMaster 2.5in Hi-Flow Cat Converter.
I will have something very similiar to stock Jeep pipe sizes. 2in or 2.25in head pipe into the Cat Converter, 2.5in between Cat Converter and Muffler, and in this case, probably dual 2in out to rear. Normally it would be a single 2.25in tail pipe. My Cherokee and Wrangler are stock head pipe, and 2.5in cat back which is pretty normal Aftermarket install on jeeps of my era which sound really nice. What I am doing should sound good and give me the tone I am looking for.
