Hmm... the piezo fuel line tach sensor approach is looking better.

You can derive rpm. You can probably also tell how long the pulse was, which is a function of rpm and control sleeve position (effectively stroke). Still need to determine the range but should be able to get a relative reading anyway.

fuel delivered = rpm * pulse duration * k
