Drilling the regulator and venturi jet is a separate issue IMHO. While not drilling them will cause a fuel pressure spike at idle; 20-25psi in a line that small is relatively low pressure and should not be pushing the hose off a barb. That type of pressure deviation is a big deal in the way that it effects tuning, but it should be insignificant to the physical construction of the parts. If that is all it takes, I would still be looking for a different pump.
