The Burger Motorsports custom billet Water/Methanol Injection (WMI) cap includes an integrated heavy-duty check valve to let much-needed air in and prevent dangerous WMI vapor/fumes and liquid from getting out!
Each cap is CNC machined in the USA from a solid block of billet aluminum, engraved with the BMS logo, and anodized blue or red for protection.
⚠️ ATTENTION: Check valve piston must be lightly lubricated if tank shows signs of vacuum. One drop of penetrating oil or motor oil in the top will keep the check valve operational. Remove dirt with compressed air before oiling.
