As long as your fuel system is sound and you dont have any lines sucking air you should not loose prime, but should that happen you will not have very good luck getting it primed. I run an autometer electric guage for my fuel pressure, the T600s we had did not have pressure gauges in them, the had fuel restriction gauges.

That is strange I've got a 1988 t600 with a four and a quarter b model in it and it has a fuel pressure gauge and it has a the gauge for your fuel filter
