Jon:
1. The RamFlo's are a great filter. I do a few car shows and like the look of stacks alone. The Ramflos are mounted securely and take some time to remove and remount. Not a quick process when arriving at a show. I am going to try K&Ns made for Roush fuel injection stacks. Slip on and off. I will post pictures when they arrive. The issue will be secure fit and hood clearance.The RamFlos are available.
The RamFlo's actually filter incoming air and do not seem restrict airflow as the screens do.
2. Tough time with fuel pressure gauges. 0 -15 pound gauges. Never read the same it seems. They are accurate at start up and then fade. Have tried Summit's brand which is liquid filled and Barry Grant's which is dry. I am on my second set and using one each.
