I did the Hengst. The original I removed was identical to to Mahle and Mann. The Hengst is slightly different but no fitment issues.
Obvious if you compare them on ECS or FCP.
My only recommendation is to have some vacuum tubing. The connection for the regulator was rotted. Started crumbling as I removed it. Just need 2” of it.
