I have a vacuum leak. I found the leak but can't find the other end. The vac. line is a very small hard line coming from the passanger side of the throttle body, to the front of the motor over the ac, and in a cloth caseing with another line going to the speed control servo thats under the battery. The battery is located on the driver side front. The truck is a 97 dodge ram 1500, 5.2, with 80,000 miles. The motor has a slight mis, so I put a small screw in the vac. line to see if it would go away, it did not but the mis did slow down even more. The vac. line is broken between the battery and the motor, closer to the battery. If you have a dodge ram can you look under your hood to see where it goes. If you know where it goes can you please tell me. Please send me a pic of the engine compartment area, at the bottom of the battery. There is a speed servo there, I need to see if there is two vac. lines on it . I do know that the vac.line is in that location.Thank you Jim

Look at the servo and see if there are 2 places for vacuum lines to hook to. Best way to find these is to open up the areas where lines are hidden and chase the lines. If it is broken, you will find the break in vacuum lines.



Being way2old is why I need help from younger minds

Cool 1- Remove your battery.
2- Under the battery, to the front is the speed servo, remove the three screws holding it in place.
3- Pull out the servo.
4- On the bottom of the speed servo is a L shape hose connector with a hard vacuum hose connected to it
(my hose was not connected). This is because the battery acid drips on it and melts it.
5- If your is connect its still bad (acid did it), cut it between the engine and the battery.
6- Before replacing clean the acid off the battery tray. (I used WD40 and water)
7- Replace the hose with a 3/16 I.D. rubber hose, cut the rubber hose so its about 6" past the servos'
mounting location, at the end of the rubber hose install about 6" of 3/16 O.D. new hard vacuum hose.
8- Remove the L shape connector hose from the back of the servo, clean out the L shape hose connector.
9- Connect the 3/16 hard vacuum hose to the L shape connector, reconnect the L shape connector to the
servo.
10- Reconnect the speed servo and the battery, do not crimp the hose.
