It won't pump at its rated flow. The simplest thing to do is to put
in the three valves that are necessary to bypass the pump. You can
then bypass the pump for transfer purposes and put it back when you
are running your engine.

While you are at it, it would be good to put in an extra Racor and the
necessary plumbing to switch between two while you are underway.

My polishing system is totally separate from the engine system.

I have 2 Raycors (MAX System) switchable for the engine system. The
polishing system is
totally separate with its own filter and pump.

I used a general purpose replacement truck fuel pump, that pumps at
around 60GPH according to the label, but probably really at around 30gph.
It is a free-flow pump, in that the engine can draw fuel through it while
it is sitting idle. The pump draws fuel through either a single Racor
10Micron filter, or the Racor and a Fram 1 Micron, and it can be setup to
return the fuel to the thank via the fuel return line, or to the engine,
priming it. This pump is available from Car Parts Stores for around $65.
