Hope it helps. Forgot to mention that if you have an EFIS with built-in engine monitor, most will allow use of a FloScan or the 'red cube' flow transducer, so you may just need the transducer.

Gents, Is anyone aware of a fuel consumption gauge that will give fuel consumption in real time? I can get one that has two flow meters but that makes installation complicated and not really cost effective. I am looking for something that works off the injectors. As usual it has to be "tweaked" with actual fuel usage. Did not Tracy have such a system? Neil.

Just about any fuel flow instrument will work, if you design the fuel architecture to allow it. If you place the regulator & its bypass prior to the flow sensor & injectors, you only need one sensor. The fuel 'dead heads' at the injectors, so it's always at full system pressure, and in the unlikely event that there is vapor in the lines, it's immediately blown through the injectors. It's how virtually every car is set up these days. It's being done in a/c, too. I'm pretty sure that Tracy has this fuel delivery architecture in the RV-8 3-rotor.
If you're patient, you can find Flowscan sensors & various brands of totalizers on Ebay for very good prices.
