I have# 12 suction line to pump about 15 inchs long and # 10 line to front. I'm seeing a 11 lb drop at the hit and then some bouncing. 21 to 10. 0n my data logger. Is this normal.

No

Where is your pressure transducer located? It does not sound like it's between the regulator and carb with numbers that high. Unless you are monitoring both sides of the regulator, meaning the high and low side, the critical side to monitor is the low side (carb side). As the regulator modulates open or closed the high side (pump side) will change noticeably. As long as the pump has a higher pressure than the regulated pressure give or take pressure drop due to fittings and the regulator orifice, the regulated pressure should remain stable. Also pressure does not equate to fluid volume.

Thanks for info. Checking high pressure at regulator and low side at carb inlet. It drops 1.5 lbs at trans brake release. Only one 45 sweep on high pressure
Is pump tired ? Anybody ever of laying pump on its side . Instead of bypass up.
