Larry, Thank you for the info on the tiny tach. I am going to order
one. Do you know if the transducer size (1/4" or 6mm) is found by
measuring fuel line? Paul

3 transducers to suit a 6mm or 7mm or 1/4 in (= 6.35mm) diam fuel
line. Measuring the line diameter is the way to go.

That's 0.236 in, 0.276 in and 0.250 in.
