seems it can hold over 120+psi since there have been people using a 12:1 fmu on stock injectors and rails and have no prolems

I have never ever in my entire life heard of someone actually blowing a fuel rail up due to high fuel pressure. Its really not something you need to worry about at all.

the BD rail doesnt use the stock injectors. they offer it as stage II i believe using 52# injectors which elimnates the need for the fmu

I just did some quick research on fuel lines... standard steel braided line has a burst pressure between 175 and 200 psi. You should never be that high anyways. Assuming all your fittings are quality and in good shape, there should be no reason to worry about your system actually bursting from too much pressure. If you have to jack the pressure up that high anyways, you're doing something wrong... just get bigger injectors.
