So I bought a 99 v6 mustang and now I am eager to swap everything from my 02 GT to the 99. I am real short on time so it was decided that the swap should be broken down in the several projects.
Phase I I wanted to start out with the fuel pump and fuel tank.
Is it possible to swap the GT pump/tank into the v6 and continue driving the v6 without any incompatibility/rigs issues?

I copied and pasted this from another forum:
K member- It is believed that the K members are interchangable, this is true between 4cyl., 3.8L V6, and the 5.0L V8, but they are conciderably different on the 4.6L. I originally attempted to modify the K Member to work, but it is completely shaped wrong and DOES require hanging. Your old steering rack WILL bolt right up.
Engine, intake, fuel injector system A/C compressor, coil packs and wires, waterpunp, etc.- Well duh!
Computer- This might not be a requirement, you might get away with a chip, dunno. I had a GT comp, so in she went,
Engine harness- This will have to be changed out for obvious reasons.
Headers- I had to change headers beuase the ones that were on the motor (rown Vic police car) were too small in diameter and the flange hit the firewall.
Transmission- I had to change out transmissions bauase her AOD-E will NOT bolt onto a 4.6L. Thankfully, I had three 4R70Ws lying around. Standard (manual) transmissions should interchange though.
Transmission harness- The harness is the same between AOD-E and 4R70W, but the O2 sensor harnesses are different. You probably can modify your old harness to work though.
Which brings us to O2 sensors. I am not sure what the differences are, but the part numbers for the 3.8L and the 4.6L sensors are different, so I changed them out to be safe. Her old O2 sensors did screw right into the GT pipes though. Again, if using the old trans
harness, you can reuse the O2s.
Brake booster- The Modular motors (even the 16 valve GT) will not clear the vacuum booster, so you will need to get a 1996+ GT hydroboost.
Brake booster to steering lines- The booster runs off the power steering pump, therefore you will need to get a set of 1996+ hydroboost and power steering rack lines.
Slight modification of the brake lines will be necessary, as the V6 lines go in from the side, the GT goes into the booster from the bottom.
Transmission tail piece- The ONLY reason why I had to swap these tailpieces out is because the Crown Vic has a larger diameter yoke, therefore the rear seal is too large, and for some reason I cannot get a rear trans
seal for a 1996+ GT 4R70W transmission.
Exhaust- Includes intermediate pipe and mufflers.
Radiator- The hoses are in diferent places and are not the same size.
Overflow tank. To match the radiator.
Modification of the drive shaft- The old drive shaft will work, but you will need to either 1. have the shaft shortened approx. 1", or 2, cut off 1" off the yoke. The splines are the same from the V6 and the autos, but the motor pushes the trans
. back slightly.
Motor mounts- They are not the same as the V6. I piked up a set of solid motor mounts for a GT for $49.00.
The dash wiring harness does NOT need to be removed for a 4.6L swap, but WILL need to be changed to swap out to a 5.0, as the pins are larger for the computer.
Starters- The starter is the same from a 3.8L to a 5.0, but are different for a 4.6L.
Alternator- Not the same as a 4.6, though 3.8 and 5.0 are the same.
A/C lines- As I stated above, the A/C ompressor is different, and the lines are too.
I have been asked this several times, and yes, fuel lines WILL bolt up the the GT rails. These do not need to be changed out.
