[QUOTE="SEABEE08FX4, post: 323026, member: 56"] You don't want to go beyond 10 psi on the lift pump, anything beyond that will cause issues ( it even states in the Ford manual to not exceed 10 psi of feed pressure to the HPFP ). If anything you can get a bigger GPH pump if needed like a FASS 220 or similar. [/QUOTE]
