the polarity is easy
the pin that goes to pink is Plus
easy to see that. and that may go to rack wiring that is RED.
keep and open mind the rack there can be non suzuki rack and have any color wires in and on the rack.
use the main harness colors as the guide, those are stock. and unchanged.
if done right , no need to repeat 4 hours lost out and back in.
keep in mind pumps have many failure modes.
all leaks bad.
lost of 12 DC power, bad.
bearings bad.
commutator bad
brushes bad.
impeller bad. seals on Impeller bad makes it useless.
hoses inside cracked , leaking where no one can see.
the motor can be bad other ways, (wires in it failed)
The SOCK can be packed. (or fell off, and pump sucks AIR with lower fuel levels.
The check ball jammed. (this magic ball keeps the fuel line changed up under pressure)
end short list.
a pump can in fact be intermittent for lots of reasons. (both by vibration or thermal expansion or contraction of materials)
I had jeep that sucked air,(pump) any time left turns fast, and 1/4tank of fuel. (or less) and a huge racket from back aft.
by bad design it did that. (tank lacked proper baffles) Jeeps first 4L (i6)did that. all did then.
But dang, ran for 250,000 miles , no failures. (related)
