Anybody use a floscan type of monitors to check the fuel usage for their engines. Thought about only buying one and maybe bring fuel line together to monitor both engines at the same time. Maybe not doable . Not sure what items need to be hooked ujp. Last time I researched the price, it was pricey and could not afford it. Running botrh engines I have been fairly accurate on using 1.5 miles per gallon. I have twin tamd 41's. Not sure were my best fuel usage is. Found a chart opn line and I thought it was about 1200 rpms and then again upwards of about 2000. Just trying to pick some brains out there. Al
