I will check connections on the pump assy. In the tank
OK...some legitimate logic here... IF there is (as you indicated) 6+A with both fuses in place, we can assume that both relays (w/ ignition OFF) are not the issue: To have 6+A w/ FP1 and FP2 inserted, the relays are in series, i.e., current in series is common to all circuit components in series.

Next, I would "divide and eliminate": see what you have at the fuel pump connector. Note: Before going further, do NOT expose fuel vapors to the potential of electrical sparks - especially when making voltage measurements with an open fuel tank!! (Course you know that, but you might not be the only one on the internet reading this!)

If it is good there, then check resistance of both pumps, measured between the input power and the ground. Also, inspect both halves of the connector.
