foothilltom 33 Report post Posted June 18, 2019 Hi guys, quick background: 302 to 351W swap. Going reasonably well. I managed to sell my old intake manifold along with all the fittings. Need a vacuum fitting for my 351W intake with at least two ports (photo of original included). Thing is, I am not sure how to search for these. Are they called a "vacuum tree" or "vacuum fitting" or something else? Anybody have a suggestion where one could get one relatively cheap? Thanks!

MN69Grande 203 Report post Posted June 19, 2019 I think foothilltom is looking for the tree/port in the back of the engine bay behind the carb on the drivers side. The parts mike65 is showing are a tempurater switch that changes the vacuum advance on the distributor from manifold to port vacuum based on engine temp. It goes in the front just behind the thermostat housing. I blocked this off with a brass plug and run the ported vacuum from my holley to the distributor. Not sure where to get the part foothilltom is looking for but you could try somengood salvage yards. West coast cougars seem to always a ton of weird ford and mercury parts. Here is what I found on their site: https://secure.cougarpartscatalog.com/vacuum-fitting-brass-intake-manifold-used-1968-1969-mercury-cougar-/-1968-1969-ford-mustang.html?attribs=88 Also if you search 'Vacuum Fitting' on Summit some generic ones popup. A final option is a standard brass fitting from the hardware store that screws into the manifold with a large out, hose clamp, and finally a series of plastic tees from the auto store.

I got my intake back from media blasting without it. Expensive part to go missing. Quote Share this post Link to post Share on other sites
