mines...tank, pump, filter, h/e, tih, heads. My purge is b4 the filter. Dont wanna push that crap back into pump/tank, but you do want to flush the h/e.
I'm run'n the raw power pump from wvodesigns...(75psi pump). Ya, theres bad blood amongst a crowd, but the pump works great and a 5yr warranty. Also got my h/e from them, i beleive...20plate h/e.
