I'm asking for a friend - literally.
One of our club's planes is an old workhorse used a lot for training. She's got a fuel drain handle in the inspection hatch where one checks the oil. I've never had a problem to place an inspection cup under the cowling and, although looking awkward, to then reach to the inspection hatch and pull the handle. My friend is a lot shorter than me and doesn't reach. Do you have any suggestion of how to go about it? Since I don't have that problem I'm not sure how to go about a solution.
The handbook suggests to let it drain for I believe 4 seconds - which is a lot of fuel, color additive and lead. Although it evaporates quickly it'd be a shame.
