I was told this was varible and i dont want to use this for my power booster. the other port is behind the carb on the manifold between the distributer and carb. the rear port is hooked into my th350.
what is the proper way to hook both the transmission and the booster up and which ports? should i t off the rear port for both?
thanks in advance | | | | | Joined: Mar 2004 Posts: 3,068 'Bolter | | 'Bolter Joined: Mar 2004 Posts: 3,068 | What kind of carb do you have?
Scott | | | | | Joined: Jun 2005 Posts: 887 Shop Shark | | Shop Shark Joined: Jun 2005 Posts: 887 | You should check the vacuum from both sources-
One is the manifold and the other is the carb. One is ported and the other isn't. For the Booster you'll probably want it from the manifold directly. If there is something else connected using a Tee, that shouldn't be a problem.
Whereever you get the vacuum to the booster from don't forget to put a filter in the line to prevent unburned fuel and crankcase gases from getting to the booster 'cause they'll ruin the diaphragm.
Autozone has those filters in their HELP product line with the other red blister pack things. Napa has them too.
