Do you check fuel before every flight? (POLL)

I open the tanks before every flight (unless it is a short stopover and the airplane is secure). I also sump the fuel every day before the first flight and after fueling. I store the bird in a hanger so I never have found any water in the fuel in the 3 years I have owned it. I did have some right after purchase, but a fuel line change and a few flights and it was gone...

 

I dump the sumped fuel on the weeds that grow in the ramp cracks. It is fairly de-green, but then, I don't like weeds

Yes, I dip my tanks for every flight. The only exceptions are when I am making a short flight [~30 minutes or so], when I may only dip one tank if it has 15 gals or more. I do not re-dip for my return short flight if all I've done is go inside and eat. Each tank holds 26 gals; after resealing them, the FBO filled them to the caps with 52.2 gals, so the labels are pretty accurate.

 

I used to fill up on return every time, now I skip that step on short burger runs or if I'm in a hurry. But I do try not to sit very long with just a few gallons in a tank.

Every flight, no matter how short. Open the caps and look inside for a visual check.  What is it...like ten seconds to check or something?  My thinking is if i don't do something on the checklist for one reason or another, then i'll eventually miss something and it will end up being something big.

I look and sump before the first flight of each day and after fueling.  Unless I'm intentionally reducing GW I keep the tanks topped off.  Since I know my fuel burn (within 5%), I use my watch to track fuel quantity.
