I have one of these, I believe this is a 250 HP "Marine" pump. Anyone have any info on this pump and how it compares to the 4911? Anyone running this on their truck? Thanks!

That's one of the good pumps. It's not the 4 plunger DB2 but it will definitely put out more than the 4911. The numbers tell the story.
DB2 - model
8 - cylinders
33 - plunger size .330"

Worth a good bit of money also.

4911 has .310" - plungers

Are the advance curves & max RPM about the same?
