The 6.5 flows 80gph the 8.5 psi flows 120gph. My car wanted the extra volume.
The 4845 has a 120gph max 6.5 psi rating. Bob K (Mr. Sixpack) told me that anything over 7 psi would blow past the needles and seats on the 440-6's. If you are not worried about concours judging, I would get the 4845 if you have a 5/16" fuel line because you can get the fittings for either 3/8" or 5/16" inlet. The OE type #4589 also has a 120gph max 6.5 psi rating but it has a 3/8" inlet. You could slip a 5/16" fuel line over it with a little lubrication if you have a 5/16 fuel line. You may have to get a fresh hose for ease of installation.
