You asked: "Also, if I switch to the double ended pump, do both ends work
at the same time or is one end a backup for the other end? If one end
failed would the other end provide fuel in the normal manner and save me?"
Since these pumps were not original to Healeys there is no correct way to
wire them and the answer to your question would depend entirely upon how
you wired the power/switch. You can choose between a SPDT ("On-Off-On")
switch where only one motor runs at a time or a SPST ("Off-On") switch (or
no switch at all) where both motors run simultaneously. In the first setup
the "backup plan" would only happen were you to switch from a non-operative
motor to an operative one. In the second/third arrangement the pumping
load is theoretically shared all the time by both motors and if one craps
out the other simply does all the work.
FWIW I have the SPDT version mounted inconspicuously through the rear
bulkhead behind the driver;s seat so it can be reached while driving.
