Should be able to use the acc pump and watch for fuel squirting out while you operate it by hand, might not be perfect but will show when the fuel level in the bowl is so low the pump cant pick any up which will be basically when the bowl is dry or very close to it.

5 seconds of cranking isnt all that much but could be longer than some like... if thats the case just break it up some, do 2 or 3 2-3 second cranks, thats what I do when mine goes dry after about 4-5 days of sitting in hot 80-90 degree summer temps, takes longer to go dry in cooler temps. Thats for my 2 cars with 1978 q-jets... my 81 with a CCC q-jet can sit for over a week if not 2-3 & it will start up in about 3-4 seconds of cranking, not sure why but the 81 is noticeable different.

Im considering a full intank pump set up like tanks inc, but until then & for the last ~10 years Ive just dealt with it by doing a couple 2-3 second cranks when needed, not really a big deal.
