Navman Fuel Flow Sensor - is it fire rated?

[Dusky 2015]

During a recent BSS check the examiner spotted an in-line Fuel Flow Sensor in each fuel line within the engine bay (twin Volvo Pentas). The item was new to his experience and looked plastic and he therefore queried if it was fire-rated. I have now discovered it is one part of a Navman Fuel Flow Sensor and Transducer kit (petrol) linked to the Navman Tracker 5600 - I think the item no is FS15. As this product line was discontinued many years ago I am having difficulty in establishing it is fire rated. Can anyone help please? - either with information or with ideas on where I might get a definitive answer, or a specification data sheet. I can't imagine they would have been fitted 10 years ago without being correctly rated, but there are no markings on the casing to indicate this.
Thank for your help, Dusky 2015

They came with an in line blank. Take it out for the BSS and refit when you refit your glass filter bowl.

Mine passed the BSS with it fitted though.

Some BSS inspectors are more pernickety than others with this kind of thing. My old Sunline failed initially due to the water in fuel sensors in the fuel filters (diesel), and Cummins eventually made some metal covers for the filters. Now there are hundreds of boats on the rivers with the Merc Isuzu Diesel engine, and mine was the first that CMD had come across to fail the inspection. The chances of diesel catching fire in the engine bay are pretty remote, unlike petrol. I personally would want any part of the petrol fuel system to be certified, as this stuff certainly ignites easily, and you are looking for the fuel system to retain integrity for a good period of time with a fire in the engine bay.

Update: Problem Solved: Thanks to rafiki and Elessar for their replies and advice. I have now found the answer! - which is that these items "comply with all relevant ABYC, NMMA, and ISO standards relevant to fuel transducers". I found this information in a Navman Marine catalogue which include descriptions of their fuel management systems. I have since been in touch with the BSS examiner and emailed him a copy of the relevant page and he is happy to accept this as OK, and suggested I keep a copy of the information with the boat's papers for future reference. In case anyone else has a similar problem the brochure can be found on-line at http://www.navmanmarine.net/upload/Marine/catalogs/plastimo_07_eng.pdf (- it is a largish file at 8.2mb), and Page 42 is the relevant page. Hope this helps others! - it has certainly re-assured me!
