Inboard gas engine -- Vapor detector recommendation?
This is for a 1939 Monk cruiser with an original Chrysler marine gas engine. I would like to add a vapor detector, ideally one with both an alarm and contacts to automatically start the blower. There is no LPG on board.

Any recommendations on product as well as a supplier?

Thanks folks,

As and A4 gasoline sailboat owner there are various products like the fireboy gasoline fume detector line that will do what you want

BUT IMHP with a carburetor 18" from my Quarter Berths if boat builds up any real level of gasoline fumes its broken

I gotta tell you one drop of gasoline will smell up my boat so i just don't tolerate and leaks :)

Re: Inboard gas engine -- Vapor detector recommendation?
Thanks for the feedback. I should have mentioned that I have almost no sense of smell, even for ordorized substances like gas or LPG.

I've used the Xintex line of sensors for LPG in the past, but doing some reading on their gasoline detection products, I came across a review stating that the sensors have a unacceptably high failure rate, but more important, that they do not reliably indicate as failed using the "Test" function. If this is the case (??) I would like to source an alternate make, preferably one that also has the capability to turn on the blower in the event of an alarm.

Looking for experience with these units, recommendations and preferred supplier(s),
