On our DA20 with wheel pants installed, I use the following tools to make the bi-weekly tire inflation check quick & easy:
1. 3/8 nut driver to remove & install the the valve cap. Careful not to cross-thread!
2. A 5.5-inch straight aircraft tire air chuck (see photo). Cost is $15 on eBay. http://ebay.to/1OGaZGn
3. Accu-Gauge from Aircraft Spruce
Until I found this straight chuck, inflating the tires through the wheel pants was drudgery. Now the only unpleasant aspect is feeling around for the valve stem. Will probably paint a red stripe on the tire to fix this.
