If you want to test the current for the fuel pump, install the in-line fuse at the pump itself and power it directly from the battery (after disconnecting it from the harness). If it blows then, it's definately the pump, and you've ruled out any possible wiring or other issues that could cause the fuse to pop at the relay point.

Don't get me wrong, it's probably the pump, but it would be a shame to spend all that money and time and still have the same problem.
