I am currently testing a marine fuel flow computer. So far it works well on my gravity feed system. It flowed 15 g/hr with the fuel line disconnected at the carb. Takeoff in the Corvair gives me 7.1 g/hr and cruise t 165mph about 5.5 - real close to what I was expecting. The nice thing will be having the fuel totalizer and be able to judge the amount of fuel left easier. The cost was only @150.00 from a marine supplier. It is easy to use and has easy to read numbers and backlighting. Just for your info...
