Thank you for the compliments Lee. Let's back up, why wouldn't the hose in the kit work with the inlets you have? Do you have the inlets with holes above the main suction hole? Does that inlet cover come off, exposing the backing plate with 1-5/8" diameter intake? You never need to replace the backing plate. Take a look at the blown up photo of the Vacuflo Adaptor, it shows the typical Vacuflo backing plate that it connects to https://builtinvacuum.com/retail/shopretail.php?part_no=517VA
, and yes the 653HW, and all the Basic Inlets, fit into the adaptor. Give us your thoughts.... Also, send us a link to the Honeywell Kit you plan on using, thanks.
