@ lovemyrangie, yes i have thought about putting in a second filter.plumbing wouldn't be a problem.again if i was get good fuel i would have done that however we don't.the filter that i have on now was to be the secondary fuel filter, but if the ome is clog and that one is new,flow rate would be affected again.in my mind it is best to have one filter.the one that is on has a 2 micron rating.
