Is water pressure too high?
If I up grade to a new 3 gpm pump vs 2.5 gpm water pump the new pump shuts off at 55 psi vs 45, will my water lines hold up ? I also just installed a new domestic 320 toilet.

The lines are probably PEX or an equivalent and they are good to 65 psi at least. Some of the plastic elbows and fittings are not of the best quality but they should hold 55, which is what your pressure regulator for street water should be set at.
