Air Cleaner Duct Tubing - The 1947 - Present Chevrolet & GMC Truck Message Board Network

SCOTI · 03-04-2019, 06:17 PM

Anyone have a p/n or source info for replacement air cleaner inlet ducting? Since these trucks had the round to oval transitions, I'm curious if there was an aftermarket duct-hose that adapts easy enough.

Please..... No 'wrecking yard' recommendations. 99% of any squarebody in a yard is plucked of useable stuff these days if you can even find a yard w/a square. If you're lucky enough to actually find a square, the heat/elements typically render the same quality plastics under hood that we're trying to repair.

LMC had it for V8 models last time I looked. The 6 is slightly smaller and did not see that size in their catalog.

I got my OEM air cleaner duct for my 83 C20 from a place called Vintage Parts.
They sell some obsolete original car parts and even parts for old appliances.
You must have the GM part number to search for parts on their website. My duct was not cheap (about $35 as I recall) but it was the correct duct for my truck.

The LMC one looks like the pre-TBI air cleaner as it lists 1981-86. Has anyone found the TBI style ducting?

They have both order the right one you need. I got the long straight one. Not the TBI! because I running two tubes to the duel air cleaner to get more air in.
