906 p pump info?

[PSD0389]

Ive had this pump on my truck for a long time and never really looked into getting any info on it. Ive never been very impressed with this pump and I have been thinking about switching to a dodge pump. So I was just seeing if anyone could give me more info on this pump and if its good for anything other than a paperweight.

Its a 402 736 906 pump

12mm plungers

Ive searched but couldnt really find anything on this pump as far as performance.

Thanks in advance
