From the creators of the world’s first B58 direct-injection fueling upgrades, comes our next generation of pumps. Our widely successful “Dorch Stage 1” (DS1) has been replaced with our latest and greatest creation; the DS15! This new pump is our “Stage 1.5” which has been completely redesigned and optimized from the ground up. Externally we’ve updated the pump packaging to provide improved hose routing. There’s no cutting, no bending, no crimping, etc. This kit drops right in with full control from the DME, just like factory. Internally, we’ve re-worked the pressure chamber, spring rates, plunger depth, and completely optimized the volumetric efficiency of the pump. 

 

Software changes are required to run this pump. If using Bootmod3MHD, or MG Flasher, simply check the box for our pump upgrade when flashing. Otherwise, please send your .BIN file to [email protected] for the appropriate software changes via WinOLS.

 

Beyond the pump performance, why choose Dorch?

Great replacements, works with eufy.
Color: X10 Parts-14Pcs
Compatible and works great with my eufy! I like having extra mop pads so I can swap out and deep wash them every few days. The dust bag replacements are good quality and have held up to 3 weeks of cleaning after 3 dogs with all of their dirt and fur.

Roller brush isn’t exact fit
Color: X10 Parts-14Pcs
Roller isn’t a perfect fit and makes a loud noise when in use. Other accessories work well.
