Thanks Charlie, yes checked the Spruce website myself and can see the 20 Amp marking on their pump image.  Will visually check my pumps  -   if they are stamped “20 Amps”,  I’ll order two of the Tyco parts in 20 Amp.  I have been fine so far but double-fine is better.

Image of the Walbro attached. Around the curve is the word 'required'. 

 

If you download the data sheet (available on the Spruce product page), it'll show that a 200% load (20 amps, in this case) takes anywhere from 6 to 22 seconds to trip the breaker. So you're fine. In contrast, Littlefuse brand ATC blade fuses are rated to blow in 0.75 to 1.8 seconds at a 135% (13.5 amps) load.
