i borrowed MoreThanCobra's pic, one of the best donor engines out there.
what is the ridged plastic hose collar for? it that to keep the hose from saggging, or is it just to keep heat off of it? if it helps keep it from sagging, i want to use it on my hose setup - as you can see from the photo, my hose is sagging just a little.
here in california ANYTHING sagging is "not allowed" hahahha
