Huge increase in fuel PSI! is that a problem??

I installed my new tank, 3/8" sending unit, fuel pump, and bigger 3/8" fuel line.

I have now incressed the PSI from what was 7 - 7 1/2, to 9 - 10 PSI!
I was told to keep it at no more the 7 1/2, so the fuel pump I purchused for that PSI for that reason (Carter). Well now I'm pushing 10 PSI. Is that going to be bad?

I was driving it awhile ago and everything seemed fine. It ran real good (better then before really).

If this is dangerous, should I put the stock fuel pump back on... that was the one at 7 1/2 PSI.

Thanks!
