Primarily Petroliana Shop Talk Forums Shop Talk Petroliana Forums Showcase and Stories, Petroliana POTM "Pump of the Month" January 2019

Early in the thread I mentioned that I would share the 300/500 series that I sold. The first three of the eleven I sold are 542`s. The 542 is a twin pump. The 542 twin is two single pumps bolted together at the base. The base has a flat spot where they bolt together. The other difference from a 541 is the reset crank is on the hose side.
