If it's leaking out the back of the master cylinder and thru the booster, they're both bad.

84yota4x4

yea thats pretty much whats goin on. i just gotta get it to stop runnin so damn rich first

so is there anything i should know before i put in a new aap? or is it pretty cut and dry? id appreciate any advice..

at the end of the last school year, my truck was runnin real rich, wouldnt even get 100miles to a full tank(stock gearing, 28's) and would puff black smoke like crazy.

The easiest way to really get that aap replaced is take the carb off. i did it w/o taking the carb off, but it was the biggest PITA. its a little rubber diaphragm thats the cause of it runnin rich. when i pulled my old one out, it looked brand new, no tears, nothin(mustve been a pinhole or something, cuz i didnt see anything wrong with it)

I put the new one, and it ran much better, back to normal.

where did you order it from? all i can find is the rebuild kits no one sells them separately.was it hard to do it w/o taking the carb off because im not to familiar with them?
