Hi Guys, The carb kit i have recommends the body and the alloy adapter should be 1/16" clear to prevent 'Frothing'.(And keep them from rattling) I'm planning on using a fat O-ring to separate the two. Good idea? Bad idea? I have replaced the rubber connector from radiator hose to an auto gas filler hose- much stiffer and should wear better. Original hose cracked after one year's use. All info welcome
I've never had a problem with rattling, and I just shove 'em together. I think when you tighten the hose clamps, the hose pushes them apart just a bit. Or the hose is so stiff that it prevents any movement.
I figure that little space can't be good for fuel flow - the original couplers (from MAP) were "stepped" on the inside to fill the gap. But, they were way soft and only lasted a couple of months. Yeah maybe an o-ring or a rubber washer, but it better be neoprene or Viton.
