In my opinion (a decade of service and warranty) modification increases your potential for failure, in very few cases does it prevent problem's
There is a very small percentage of failure of the fuel pump, certainly no worse than the failure rate of an aftermarket pump
Not to mention all the PITA of locating a good spot for an external pump, fabrication of the plug, spigot, fuel pressure regulator and return hose etc etc
Frankly, I think you are causing more hassle than you would ever fix
Just ride it, you got worse thing's to worry about in life
