Mark, for anyone who drives their car long distances frequently, as I do,
having a backup fuel pump installed is a great comfort. A failed or balky fuel
pump is one of the few items that can stop you on the side of the road or cause
you great inconvenience. I preferred not to have to deal with installing a
spare pump at night, in the rain, in the middle of nowhere, so I installed the
second pump in series (for simplicity of installation) with the first.
On two occasions during the last 10 years, I have had occasion to reach under
the dash and switch to the other pump when my SU pump was apparently not going
to start the car. The backup pump got the engine going right away. Switching
back to the first pump still allowed the engine to run. No idea what the
problem was, but as I said, it's a comfort to have the option of another pump.
I usually use the SU pump on the outbound leg of a trip (as I did on Thursday),
and switch to the backup pump for the return trip home (as I will do on Sunday).
Since I can turn both pumps off, I have inadvertently verified the "security"
feature by forgetting to turn the pumps back on the next morning at the hotel.
The car started fine, but ran out of gas before I got out of the parking lot.
My engine will run for only 1 minute and 20 seconds at idle starting from full
float bowls with both pumps off.
