    I am looking for an air shut off valve for my engine; it is a CAT 3406b.

    I just want to be safe and be able to shut it down should I ever have a run away diesel.

    My preference is something manually activated.

    Has anyone got experience with this or fabricated one?

    Positive air shutoff. Just Google it, tons of companies out there make them.

    Ehh, you got soft hands.

    3406's don't run away unless you F-up overfueling 'em

    Running away was always Detroit's Claim to Flames...
