Source for replacement boost sensor?

[Streetfighterkz]

A guy that owned a kz1000 I worked on previously, recently picked up a Turbo. He told me “the boost gauge doesn’t work and the vacuum line by the gauge cluster is unhooked.” I told him it sounds like the boost sensor may be bad and someone ran a mechanical boost gauge but I don’t know. I would think the bike would not run properly with a non-working sensor. Anyways, if the sensor is faulty, is there a compatible sensor offered from someone else ie Napa or the like? I’m most likely going to go over the bike for him at some point, but would like to know beforehand. I looked in the New Parts Resource but Lorcan’s posts about 3 and 5-bar MAP sensors were 19yrs old.
