They have been known to seep air , especially in older designs like 2004 or so , where the line goes into the fitting . Sometimes they leak when filled to 70-80# and only leak down to 40-50# and then stop leaking. The line might not be seated just right .
You could try to fill them up to 80-90# then spray the fittings with a soapy water solution and look for bubbles. That might find a leak.
As mentioned using an on board compressor is the easiest way to handle it.
Installing the fill valves at a location where it's easy to fill certainly makes life easier.
Some people install the valves inside the fuel fill door.
