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.

No, my fuel system is completely different than the factory system and is built for volume.

Sounds like the pump is starting to get a little weak, or your lines are degrading.

Its not meant to gain you pressure, opening up tose holes with only let more volume thru and actually drop pressure, and if I remeber right the fuel pressure port on the filter base is before the jack pump so any increase in flow after that port will lower pressure.

I didn't think long enough about it, I forgot that the fuel flows into the front of the base as it sits on the engine.
