FC3S owners using Holley Red pumps.
Don't do it. Holley reds and blues are noisy and leak.
If its a fc3s second gen rx7 just use the in tank pump with a aeromotive bypass regulator part #13301
Your stock N/A pump is far better than a holley red. This regulator also comes with a EFI spring if you decide to upgrade or need it for another build. This will also work with blow through turbo unlike the holley.
