SOLD! This is an all aluminum vacuum reservoir made by CVR Performance. It has a built-in check valve, vacuum gauge, mounting flange etc.. This unit was installed, then removed; used for less than 100 miles. Very nice piece. Worked well. But when you have multiple other vacuum issues, then fix the issues, the vacuum canister seems no longer necessary . Retails for around $115 + shipping. $75 + $10 to ship. Thanks
