Rewire the fuel pump

Q1 - Can I get away with the stock Fuel Pump, but rewired? I'm trying to avoid fuel cut at 18 - 20 psi.
Q2 - At max 18-20 psi boost, will the stock engine (7 bolt 1G) take it, or am I pushing reliability of the engine? I drive pretty hard.

A1 - For $75 it's not worth going lean and blowing up the engine. Buy a new pump.
A2 - Running lean/knocking will kill your engine before crank walk if you run 18-20psi without a decent tune.
