I have an 85 Ford F350 and need to know the vacuum readings at the pump ?

Is this for the 6.9? Its 20 lbs vacuum,Engine are natural aspiration, and a diesel is considered a open intake,so it cant create vacuum so a pump is installed for the brake booster and whatever else.3_16_2012_6_21_42_am.jpg

I have hard break peddle with little breaking power. I checked the vacum pump a found 13 inches of vacum. the hose removed from the vacum booster will **** your finger to it with motor running. the truck...

Hello, Check other Vacuum lines for leaks. If you have a 4x4, they can have Vacuum operated hubs and a leak anywhere will draw down the Vacuum. I found most pumps running at about 21psi. Check for a Vacuum Reservoir. The older models used one looking like a coffee can and they would rust on the bottom and leak.

If you take off a vacuum line and use a hand vacuum pump, you should easily find a leak on one of the remote lines. Another test idea is to remove the Vacuum pump lines, put in soapy water, and pressurize with about 3 PSI. Any vacuum leaks will blow bubbles and soapy fluid. Its your choice on what to do. I would reserve the soapy water for a line I find to leak with a hand Vacuum pump.

Many of the people wih your problem replaced the vacuum pump and were good to go. But if you can measure the vacuum and find the leak, you may save money on a part you do not need.

What does the vacuum pump on an 91' f350 (7.3l diesel) run?

Good question. On petrol engines there is a throttle plate that governs the amount of air entering the engine. At idle the throttle is almost completely closed and a result is the a vacuum is created in the inlet plenum. This vacuum is used to control ancillary engine related functions: opening the engine's exhaust gas recirculation (EGR) valve; operating the intake manifold runner (IMR) valve; moderating the fuel pressure regulator (FPR) function; and in governing in-gear duration (automatic transmission) and vehicle functions such as central locking, fuel cap door release and brake servo assist. OK so what has this to do with diesels? Diesels do not have throttles, engine speed is governed by fuel injection volumes. Without an air throttle the diesel engine does not have a vacuum to run the ancillary vehicular functions. Since many of the ancillary devices have already been made to operate with petrol engines it is simpler add vacuum pump to the diesel engine and use the same components to do the same jobs.

2001 f350 4wd quit working

Most of the time it’s a Fuse, PVH,(Pulse Vacuum Hublock) ,Vacuum line or Vacuum pump.
ESOF 4WD Trouble shooting It is easier to trouble shoot the system if you have a “Mityvac” vacuum pump. Turn the ignition switch to run (you don’t have to start the truck) and the air controls to vent and the fan control to low. If the truck’s vacuum pump comes on wait until it stops running before each test (open the hood and you’ll hear it better). First you need to remove both lines (left and right vacuum lines) from the hubs. Plug the passenger’s side line and attach the vacuum pump to the driver’s side line. Switch the dash controller to 4WD high. The vacuum gauge should go to 10 in.-Hg. or higher. (It should hold the vacuum at 10 in.-Hg. or higher for 45 seconds on engage and 15 seconds on disengage.) Repeat the test plugging the drivers side and testing the passengers side. If you have the right amount of steady vacuum the problem is probably in the hubs. If you do not have the right amount of vacuum or it is bleeding off, plug the lines back on the hubs and go to the next step. Second remove the vacuum lines from the PVH (Pulse Vacuum Hublock). This is the solenoid located on the passenger side fender well behind the battery and in front of the vacuum pump. Plug the vacuum tester into the lower hose and wait for the vacuum pump to build back up and shut off. The vacuum gauge should read and hold steady at 10 in.-Hg. or more. If it does, the vacuum reservoir should be fine and not leaking, so go on to the next step. Third, plug the bottom line back to the bottom of the solenoid and hook the vacuum gauge to the top barb of the solenoid (not the vacuum line but to the solenoid itself). Try switching between 2WD and 4WD again. The gauge should read 10 in.-Hg. for 45 seconds on engage and for 15 seconds on disengage. If it doesn’t it is probably the solenoid (PVH) on the fender that needs replacing. This was my problem so this was as far as I have gone. If all these things check out, THEN you need to go to the hubs and check them for leaks with the vacuum tester. Most of the time it’s a fuse, PVH, vacuum line or vacuum pump and not the hubs. Does your ac/heater work properly when you switch modes (IE linger before going in?) or sometimes stay on defrost? These trucks have a vacuum pump that controls it and the auto hubs.If the vacuum pump or hose,fails those are easy to see symptoms.

Hi jcallihan. If your truck doesnt have hydraboost then the problem will be a bad vacuum pump. This pump is located to the drivers side of the engine just below the a/c compressor. It looks similar to a mushroom and is belt driven. This may look ok but if the diaphram is busted inside it will not create vacuum for the brakes to work properly.

Heater valve is not getting any vacuum

Try removing the vacuum hose at the back of the vacuum pump start the engine and see if you can feel it pulling a vacuum it should **** you're finger in a bit or if you have a vacuum gage hook that up and see what it readsshould be at least 12-15 in vacuum. Also is the heat stuck in defrost mode ?

1997 Ford F-350 7.3 L Diesel..........brake failure

With no leaks and a little braking action returning by pumping the pedal I would suggest looking into a master cylinder. Low brake fluid level in the master cylinder will cause the brake warning light to illuminate (possibly, also the ABS light).

If the truck has the 7.3L diesel, it will have a vacuum pump which supplies vacuum for all vacuum accessories. I believe if the vacuum level drops below 10 in. of Hg, the brake light will illuminate. If the vacuum pump fails you'll know it as the brake pedal will require quite a bit of effort to effect any braking effort.
