Accurate fuel flow

[Dale Campbell]

I have a 337H that I installed a Shadin and love it. I always fill tanks myself to the filler neck and plug in 148 gal in the Shadin. My tanks hold 155 gal. I do notice that the right tank always drops first and continues until the 1/2 point. Than the other tank catches up. I never let the tanks get under 35 gal total on Shadin, so I know I have reserve. I also watch old tank gauges when they get to 1/4, so I know they are not off by to much. Some day I might drain all fuel by hand to see if gauges go to empty. My old instructor had a 337F with separate Aux. tanks. We use to fly until the aux. went totally empty and engine sputtered. I was not to fond of that. We always had to jump on fuel pumps to keep engine running while switching tanks. Dale Campbell
