[QUOTE="westgl, post: 99320, member: 2025"] Yes on the other site they talk about drilling. But that is [u]Not[/u] what I am talking about. I am talking about using the Vacuum hole on each side of the plenum, getting two brass fittings, and copper/brass tubing. Going into one of those threaded vacuum holes, with the copper/Brass tubing, using the fitting to seal the thread, and against the brass tubing, Those fittings would be your vacuum seal, the tubing would lay across the raised plenum floor to heat the fuel spray & the Plenum floor, heat transfer should heat the whole plenum. Why drill a few New holes when you can maybe use the ones that are already threaded for a pipe thread. Instead of sealing them, use them for heated coolant. That is why I was trying to see some pictures of the vacuum holes and thew inside of the plenum. I was hoping that the vacuum ports were just at the right height so a tube would go in and lay right on top of the high point of the plenum floor and go straight accross, to the other side. But I dont remember how it looks in there, and relationship between the vacuum ports and plenum floor. This could be a very good way to heat with No mods to the plenum other than two fittings and a piece of brass tubing. [/QUOTE]
