Vacuum ?

[old rat 49]

The brake booster I used for my disc brake conversion (firewall mounted GM) has a large vacuum line and the line off the stock intake is quite small. If I pull that pipe reducer that is stock on the manifold and increase the size to match the booster line and then "T" off that to reduce to the wiper size line will that give me the vacuum for the booster and the wiper motor ?

It should work okay that way, but you might want to consider getting a vacuum reservoir so that your brake booster can take a big gulp with being limited by the small connection. Many of us have them for the wiper motors, and I found a nice place to hide mine at the back right corner of the engine compartment behind the body brace; it's actually under the passenger toe board.

Replaced reducer fitting on intake and went to 1/2 inch line from there to booster. Will have to make my own "T" to pull off the 1/4 inch wiper hose. Noboy seems to have one that size. Will check out scrap yard for a resrvoir next time I go. Booster and pedal assy done today. Even used the old pedal. Still want to replace all the old steel lines before I hit the road.
