Yes i ran one when i had my old stealth pumps before i had to remove it when i installed the gen3. Something about too much gear backlash if you tried to use it with the Gen3 LOL
However i have another set of dual pumps to improve some efficiency out of my little 250/80s, and i got another dieselsite adapter sitting waiting to be installed with the pumps. I feel its the only proper way to feed the rear pump, from the lowest possible area on the reservoir to prevent cavitating the rear pump by running the reservoir dry(enough) on startup. I am using the block also to dump my IPR return back (where-ever it goes, not back to the crankcase behind the cam gear, the other port). I have all the fittings and such just lacking motivation to install them because it's going to be a cluster*** of hoses to deal with.
