Part ID please.

Someone probably would recognize it but if there's a part number on it it would be a good idea to post part number or better yet a picture of it,,,

[Alan H. Tast]

That doesn't look like a factory-installed part. I suspect previous owner add-on "gimmick" item. What is it connected to and/or its function?

[Jim Wulf]

Part id please. Dave

My guess is an aftermarket windshield washer pump.

[Alan H. Tast]

Jim, that was my first thought seeing the hose nipple. Another photo showing more of the engine bay for context would be helpful, too - it looks to be mounted against the driver's side inner fender, but where does the wire attached to it come from or go to?

[Ducksface]

I've not seen one shaped exactly like that.

[aa010175]

Alan, it is bolted to the driver side fender. It has a factory bracket. The one hose runs from the unit to the intake manifold for vacuum. My car has a vacuum tank over by the battery. Is that normal? No wire run to the unit. I’m trying to fix the wrong that the restoration did. I have all the books and manuals but some are reprints and difficult to read. Dave

[Alan H. Tast]

OK, now I'm even more confused. The part appears to be from a much-later Ford and certainly isn't original to the car. Likewise, the other photo shows that the original brake booster and master cylinder have been replaced with something newer, and the brake light switch relocated. The photo of the part has some numbers on it - the bottom row doesn't appear to be a Ford part number from the '80s or '90s. There appears to be a part number across the top of the part above the Ford oval trademark (another tell-tale sign it's from a newer era) - post what that number is. Chances are it begins with an E or an F indicating the 1980s or 1990s for decade of manufacture, with the second character being the year in the decade, then a letter to indicate model line, then followed by a fourth letter. The number that follows it will help narrow down the basic part number and what it is. Chances are if the vacuum line is connected back to the brake booster it's going to be part of the braking system.

I don't think we're getting the whole story here - the car's definitely been modified in more ways than a couple. Again, photos of the engine bay can answer some questions like whether the vacuum reservoir over by the battery is the factory one used with the A/C system (or not). I really want to see what else has been changed may help to provide some additional context here. You're not dealing with a car restored back to OEM specs.

Alan,
It's a vacuum boost motor from a modern diesel engined Ford truck based vehicle.
Diesels(generally)do not make vacuum so a pump is needed to operate vacuum actuated items.
I used versions commonly on wildly cammed cars.

OP
You're plenty of 1,000's of dollars from reversing that brake system back to stock, whatever it is.

So, if it's a vacuum boost motor (pump?), that makes me wonder if the cam that's in this car is a little more 'radical' than stock and translates into less vacuum developed when running? Again, another reason to evaluate what else has been done under the hood.

[aa010175]

The engine is stock as far as I know. I removed the vacuum pump. I see no wire running to it and don’t understand why someone would attempt to install it. I suspect someone was thinking it would help the disks brakes. I am trying to straighten out the poor workmanship. Here is some more photos. Dave

This makes one think what else has been changed on the car.

[Ducksface]

Since that pump causes nothing to be modified except a splice in a vacuum line and a spade for power, I'd keep it handy until you find out what that power brake unit/diaphragm is.

It Could be that two brake pumps and you're out of brakes for a moment without that vacuum enhancement.

[ICON 1956]

Good point Ducksface ! Did you drive the car after you removed the pump? If so was there any difference in driving or stopping.

[aa010175]

The pump has no electricity to it so it didn’t work. No wires around the area to be used on it. I removed it with no change in car. Dave
