I replaced 4 fuel pumps and a sending unit and found out it was simply the wire connector at the gas tank. This is the connector that splits to the fuel pump and gas gauge. I simply cut it out and direct wired to the tank. No problems for 5 years.

99 rhd jdm had no signal to fuel relays so i bypassed the system. From battery straight to fuel pump with a toggle switch on steering column.
Been working fine for 2 years and gives me a hidden fuel cutoff switch as well.
