Gary Lewis Posted December 27, 2018 Share Posted December 27, 2018 I can't find that one in the catalog, but it does look to be the right one. Link to comment Share on other sites More sharing options...
1986F150Six Posted December 27, 2018 Author Share Posted December 27, 2018 I can't find that one in the catalog, but it does look to be the right one. It is the same as the one I found for Jonathan, except the original one [not replacement] is finished more smoothly, especially where the vacuum hose connects.

Isn't that cool. I know where there is one on a parts truck that I'm going to grab one of these days. I wonder what dictated the installation of one of these? I have only seen two of them in the flesh, and they were both on 1985-1986 trucks. I've looked at several 1980-1983 trucks, and they all had EGR valves.

I've seen 1980-1981 300/6 engines with EGR valves under the carbs, and I've seen two different 1986 F150's with 300/6 engines with these same EGR delete plates installed. That's in reverse order...chronologically. Link to comment Share on other sites More sharing options...

I wonder if that made a difference? Link to comment Share on other sites More sharing options...

I don’t have a lot of input regarding what trucks got this EGR delete... except that the junkyard one that I got the sill plate with the emissions tag (without EGR) was a 1986 F250 from Canada. It was a light duty 6300 gvwr with a semi floating rear axle. (Only 200 lbs more than my ‘81 F150! 🤷♂️) Regarding the spacer itself, the one David sent me is slightly different. The engineering number prefix is D3, not D7, and mine does NOT have the vacuum port for the crank case vent hose, which I presume is the function of the large port that you can see on the eBay one.
