Al,
I've looked over the website and see the stuff on fuel flow measuring

(down to 0.1

gph which is the best accuracy I've seen so far).  What I don't see is:

  1. any indication that the fuel flow sensing is differential, or
  2. any prices for fuel flow sensors (on the price list that has all the

probes,

     etc.).

I did find fuel *pressure* sensors, but we all know those aren't the same

things.

Grand Rapids' web page calls the option a "FloScan flow sending unit."

Al, where did you get your information?

I called them directly.  The differential flow option is apparently not yet
on the website.

I might point out that this is kind of academic as a computerized fuel

injection

system like Tracy's knows exactly how much fuel is actually being injected.

Tracy's

entire EFI system cost little more than most flow meter based measuring

systems.

This is true; but Tracy says it will be some (undefined) time yet before
that option is available on his ECU.  How long do I put off plumbing my fuel
system.  Maybe I can find someone to help him with that.

I have some of it done. But it dropped in priority when I started overhauling
this engine. If anybody wants to take on this project let me know.
