changed fuel pump, now no brakes and high idle
Changed my fuel pump and in the process I took the air cleaner assembly etc. off so I could dump a little fuel in the carb. Well I got the truck running again but it idles really high and the brakes arent working so I assume I knocked a vacuum line off somewhere but I cant see anything not hooked up? Any idea where to look? Picture would be great if you have them

Re: changed fuel pump, now no brakes and high idle
maybe you split a vacuum line? is it possible you have the air cleaner on wrong so the linkage is hanging up?

Re: changed fuel pump, now no brakes and high idle
The brake booster line should come from the rear of the carb at the base or a port on the intake also at the rear of the carb . I would look there . Just follow the Vac line from the booster to the vac source . Frank

Re: changed fuel pump, now no brakes and high idle
Frank has the answer. The vacuum line that feeds the brake booster is of or split as Bob suggested. That's killing the brakes and causing it to go lean as well.

Re: changed fuel pump, now no brakes and high idle
Maybe this could help you.. this is the vacuum line and goes to the brake booster

Re: changed fuel pump, now no brakes and high idle
Thanks for the help everyone, I R DuM ha ha. Turns out the cruise control module got stuck and was keeping the throttle cable pulled, the brakes worked ok the motor was just trying to push through the brakes ha ha.
