I have changed my fuel lines to -8 and am now looking at the best way to control the fp at the rail.
I have seen a few after market ones but nothing has jumped out yet, most being -6 though. Any BTDT?
The best i found is this

Ideal for race cars with up to 2000hp fuel systems.
• Special internals to handle all types of race fuels
• 2 x AN -8 inlet ports
• 1 x AN -8 outlet port
• 1 x AN -3 vacuum source adapter
• 30-70 PSI base pressure adjustments
• 1:1 ratio
• Aerospace-grade billet aluminium construction• Supplied with a mounting bracket and a gauge port blank
And use a blank fitting on the second inlet
