It may sound like a daft question, but until I started to cut the cowl for my new Renegade I thought nothing of it.
I use a 3 pipe system, carb, fill & exhaust pressure, and when I filled up my Stik ( exposed engine ) I would pump fuel in until it just started to come out of the disconnected pressure pipe off the exhaust.
Now, with the Renegade the exhaust including the pressure nipple is mostly covered by the cowl. There will not be a problem with the fill pipe because I can drill a small hole at the bottom of the cowl for this to exit, but how do I know when the tank is full?
How do you guys usually work around this?

one method I have seen used is to fill it without the cowl counting the nuber of turns a hand pump needs to fill it. (or nuber of seconds for an electric pump). But this only works if the tank is empty (you can drain the tank before a re fuel.

my Yak has the same problem, i just watch the pipe connected to the silencer pressure nipple and as soon as i see fuel coming up pipe i briefly hit the pump in reverse and then stop it ! i peek at the pipe on the silencer by looking through the cut out for the cylinder head

I fill cowled models through a fueling valve using the pump in a Ripmax Power Panel. I find that there is very slight change in the pump "note" just as the tank is full. So I wait, hear the note change and then turn off. This is 99% effective. On the rare occassion I miss the note change the fuel over flows into the exhaust. Other than being a slight waste of fuel this has not proved to be any other problem.

I use a hand pump and you can easily feel the difference when the fuel hits the vent pipe.

My Acro Wot is fueled with fire and brimstone filtered through a virgins hair then dripped in to the fuel tank off her toe
 
 
 
or I use a hand pump and watch the clear breather pipe to the exhaust, when fuel gets there i stop pumping.

On a model in which the exhaust pressure pipe was hidden. I put a fuel filler valve in the pressure pipe so that with the "filler" insert connected to a small bottle, this took the over flow and showed when the tank was full. I may be tight but the fuel saved gave another flight each day. Remove the insert and the pressure goes to the tank.

If you can see the fuel level inthe tank you are filling from, a ruler on outside would tell you haove much has gone in.

I hope he hasn't got a battery of jokes like that
 
Mind you there is always one bright spark trying to do the hard s(c)ell for electric flight.

I think the new Dyson handheld does, Phil - but the battery only lasts about six minutes!
