Pete regarding parts to re-route PCV's-
My Subaru has large PCV and breather nipple fittings, think they are in the range of 5/8" or 3/4". I look for various tee's and assorted fittings at O'reilly Auto Parts, NAPA, other parts houses AND various hardware stores.Auto parts stores- look for the Help! brand section. Home Depot, Lowes, etc. carry a selection in the Irrigation/Plumbing dept's. To be a Gadgetman also means being resourceful, I've learned to cast a wide search. Hoses are easy just look at heater and fuel hoses at any auto parts store, and hardware stores will also have some plastic and vinyl kinds in irrigation, though be mindful of heat compatibility. The clear/translucent and loose weave fabric reinforced vinyl kinds can be good to be able to see what's going thru the hoses, even just a short section properly placed. Another type supplier is Hydraulic supply houses for tractors big rigs, well drilling mining etc. Farm/ranch supply stores are likely places too. Any such store that cariies Parker brand stuff is a good source for fittings and hoses, very high quality though spendy.
With high quality fittings and hoses we can consider innovative approaches. Think of any trade that plumbs liquids w/ flexible lines, then look for their suppliers.
I've been experimenting w/ another approach to supplemental fuel vaporization, and use of parts from these kind of suppliers has been vital. A different method from Dan's supplemental injector type- that of deserved and growing fame-, a method useful for those with carburetors as I have. But that's another story, I will tell of it soon.
hope this helps Pete!
