The pump has an internal valve that will try to keep the pressure. The aftermarket pumps don't seem to work as good as the original GM pumps in my opinion. Miner bleeds off too on my Walbro. The main thing is that your fuel pressure doeant climb past what you want .
Did you ever make any progress on this? Can you post your tune and a log, I might have some time to look at it tonight.
