Yeager Hi Performance finishing up their own custom stainless steel direct port methanol injection system on a 2015-2018 Ford F-150 2.7L EcoBoost. We supplied them with everything needed to run a separate check valve on top of every nozzle holder preventing fluid from siphoning past the valve and keeping the system ultra responsive. No delay as others have with single check valve/solenoid direct port systems. Need help setting up a direct port methanol injection system. Call ProMeth 801-447-2559 and do it right the first time.
