RPM 1,190 Report post Posted April 23, 2015 Any ideas what this might be? My wag is that it slipped into the exhaust manifold then traveled upward. The o.d. is 1/4" and about 15" overall length. I looked thru some manuals and catalogs without luck. Thanks guys. Quote Share this post Link to post Share on other sites
Rsanter 152 Report post Posted April 23, 2015 Choke heat riser tube It goes into a boss on the side of the stock exhaust manifold and transmits heat to the mechanical automatic choke Bob Quote Share this post Link to post Share on other sites
RPM 1,190 Report post Posted April 23, 2015 Thanks Bob. I suppose I do have a few active brain cells. Guess I won't be using it with headers. Quote Share this post Link to post Share on other sites
Ridge Runner 1,113 Report post Posted April 24, 2015 Yep that is what it be ,but it looks like the nut is missing that attaches it at the choke . Quote Share this post Link to post Share on other sites
RPM 1,190 Report post Posted April 24, 2015 Thanks RR, but with headers I won't be using the tube. Hmm, wouldn't the nut be captive? I wonder how it came off. Quote Share this post Link to post Share on other sites

RPM 1,190 Report post Posted April 24, 2015 Much too small and bent for a dipstick. It's the heat tube to open the vent like Rsanter confirmed. 1 Footcutter11 reacted to this Quote Share this post Link to post Share on other sites
