1995 vacuum diagram

I know the engine vacuum is Very simple, but when I bought my truck, all the heater air control vacuum lines have been bypassed.

Does anyone have a vacuum diagram for the HVAC system and where everything gets hooked up?

Don't just have the time to tear into the truck and trial and error the system.

There's actually no engine vacuum. Here's a scan of the HVAC vacuum from the 1995 EVTM, assuming you have A/C. A bit fuzzy, sorry.

I guess I didn't phrase it right. What I shouled have said was the vacuum system in the engine compartment is very simple. I do know there is minimal vacuum on diesels and that is why we have the vacuum pumps. I guess I better be more careful with my phrasing in the future.

The diagram is exactly what I was looking for.Is that out of a Ford service manual? I know it's not in my Chilton.

Many thanks. I'll work on it this week.

That is out of the Electrical and Vacuum Troubleshooting Manual (EVTM, which is one of the factory manuals). It is available from Helm Inc for about $22 to $30 in paper version, which I recommend (much easier to read and flip around in). The EVTM is probably one of the most useful manuals you can have for these trucks. I have 94 and 97 in paper and 95 and 96 on CDROM. Both paper versions are beat up and dog-eared! Cheers!

It's from the Ford EVTM - Electrical and Vacuum Troubleshooting Manual. Part of the Factory Service Manual set; it's a separate book from the Powertrain and Chassis/Body manuals. Indispensable for nailing down electrical issue, or doing mods with the electrical system. Don't get much chance to use the vacuum diagrams, unlike with the gassers.

I have a 95 f350 w/ 7.3 powerstroke. My vacuum pump failed (bearings went) my question is while checking the problem i notice i have an additional pump mounted on the lower left side of the motor with its hose coming around and T into the line off the pump at the top right of the engine( the one that broke) i cant find any pics, diagrams,etc showing this second pump. Is this factory or did someone add one ( no idea why they would) both run off the serpitine belt.

The (factory) vacuum pump is on the left side of the engine, below the A/C compressor and above the P/S pump. It has a smooth pulley, and the back of the belt rides on it. Is that the one you replaced?

Can you post a pic of this second pump?

So it's on the RIGHT, between the crank and the grooved idler? Yeah, that's definitely aftermarket. Is it smooth or grooved pulley?
