fwiw, when I swapped the XL-7 drivetrain and electronics into my swb, I didn't want to bother dropping the tank to replace the fuel pump. I believe the Tracker's (2.0 liter 4 cyl) pump had an extra wire that the XL-7 harness didn't require, so it was just taped off.
Long story short, I've been running my XL-7 engine with the 4-cyl Track/Vit's fuel pump for almost 60,000 miles, absolutely no problems. Except for one wire you won't need (possibly...I was also swapping between an '02 and an '03), they're completely interchangeable. So, if you should happen to find one pump is cheaper or more available than the other, fear not.
