Hi all, replaced FP 05' 996tts, for low fuel pressure; <20 psi with OEM from Sunset also replaced Venturi pump lines and FF.
Car runs great, but fuel pressure is now 75-80 psi at idle. FPR is 3.8 bar I think. Should I worry?

Also, what is the purpose of the 3rd fuel line that connects to the sender bonnet. It broke off trying to remove the quick connect.
Nothing comes out of that line. Is it a tank canister vent or what.
