Hello! 86 Bronco XLT 5.0 efi. I need the fitting that screws into the intake that the heater hoses and sensor screws into. It has two threaded ports and a nipple. The nipple is rusted almost off. Any idea where to find one? Anything I can use to make it work some other way? Thanks in advance for any input!
I dont think you will find it other than a junk yard or dealer.
I would thing the JY would have something as you can also look at cars not just rucks.
Wish I knew the name Ford called that to look on Ebay.
Being EFI it needs them other sensors I bet
If the JY dose not pan out you might try cutting that nipple off flush and tap the hole for NPT (pipe thread) and thread a nipple in the hose will fit on.
If you use brass nipple it will never rust again, but steel would work also.
If you find it leaks then use steel and weld it to the part with the holes in it.

Actually, the small nipple can be tapped out to 1/4" NPT. Do what needs to be done to clean it out. Chase / re-tap threads. I deleted the coolant to the throttle body on my 1986 truck so I just plugged the hole with an ordinary pipe plug.
Why does the coolant go to the throttle body anyway? I've always been curious about that.
Depends on what you want to believe. Some argue it's to prevent freezing of condensation on cold morning starts. I'm in the camp that thinks it is to buffer heat transfer to throttle body from the EGR Plate.
For those that don't know the 302EFI, I went out and took some photo's. DOn't mind the dampness, it's been cold, except for this morning it rained, and now it's 60F with more rain coming. The area is hard to get a good shot of.
I seem to recall a while back, someone made up the tree using pipe fittings...
I like the idea of just cutting off the rust and tap for NPT.
Yeah, that sounds like the best route. Are the nipples on the throttle body threaded in?
They are pressed in. They are very hard and the TB is soft. I tried to remove one of the nipples that was leaking on my TB. Subsequently, I discovered a crack in the soft material. Can't be sure if that was the leak or if I caused the crack trying to drill out the nipple. The dimensions of the TB are not conducive to tapping. Nipple OD size is too big for 1/8" NPT and the body is too narrow to tap 1/4". That's one of the reasons I deleted.

Ok. I'll just plug them. Don't want run the chances of cracking the throttle body. I live in Southern Georgia, so I don't foresee the need to keep the throttle plates from freezing, and the fewer places to leak on a 37 year old truck the better!
Looks like yours is not long for this world either.
No kidding! That's bad design using ferrous metal for that tree. The combination of heat and moisture is perfect for corrosion. I'm thinking a new replacement tree made from brass or stainless steel would make sense. At the very least brush on some Fluid-Film and keep it protected with a touch up periodically.
