I didn't know what that was either and since the old carb had nothing like it I just capped it.
'84 CJ-7: Yota axles (spartan locked front, e-locked rear) 4" BDS, 1" Daystar & 3/8" shackle lifts, 35" X-Terrains on steelies, YJ Tub & family roll bar, heater blower upgrade, 4.2L w/MC2100 & Team Rush, Warn 8274. Rebuilt 4.2/4.0 hybrid, AX15 and twin sticks/clocking ring waiting to go in.
The advertised position for a topless, dirty jeep girl has been filled......by my wife. Thanks to all that applied.
<------------and yes, that is her. :-D
On my 78 that attaches to the hot end of a small heat exchanger (not sure what AMC or MC called it) that fishes down into the intake. It provides hot air to the choke to open it up as the engine warms. The other (cold) end of the heat exchanger attaches to the 45* elbow hanging from the bottom of the filter base (shown in your pic)
One more question: is there a good part number for the air filter assembly?
Any generic Holley four barrel FILTER will work.
I used a stock ford FILTER HOUSING on mine from a F150, I did not like the idea of a wide open air filter on something that might be waist deep in the mud of creek crossing one day.
