Thread: How do I hook up a vac gauge?

Tweet

I'd like to hook a vac gauge up to the carb vac line that powers the vac operated wipers so I can keep track of the vac for the wipers. How do I do it? And can it be done?

If you want to just check the vac. just hook the vac. guage up where the wiper vac hose goes below the carb. . If you want to keep the vac. guage hooked up all the time, put a "T" in that line & run the guage off the "T".

Sure it can be done MATT. All you ned is a t fitting that is the same size as the line.cut the line and insert the two straight sides into it. Then run the t leg side to your hose for the vacuum guage. That should do it for you.

He He He Oldf100fordman .. I musta' hit submit before Ya'.

Looks like we were both answering at the same time PRO Z.

MATT, you could even unhook it where it goes in to the wiper motor, install the T, and that way you'd be using the lest amount of hose for the vacuum guage and not clutter things up.

DOH!!!!!!!!!!

Danged, STREETS, you are probablly right. I remember some makes used that and some used direct manifold vacuum where you could stop the wipers just by hitting the accelerator.

Been exactly 40 years since I've owned a Stovebolt six so my memory is foggy. Heck, it's foggy most the time anyway.

Yeah Matt, YOU could do it that way But, the Wipers originally ran off the Fuelpump on your car.. Hehehehe

I replaced the fuel pump with the exzact replacement from what was there and there wearn't vac lines coming from it and, they still work. are you saying mine was converted?

I looked at the vac line again, it's connected to the intake manifold,

Heres an updated pic of my car

Well, MATT, if it comes off the intake manifold. follow PRO Z'S and my earlier instructions and you've got it hooked up correctly.

Yeah, we retired that old boat and got a new 1 which is at our house in savanah Ny. That old boat had a tree fall on it and we bought it with the cabin crushed in for somthing like 2 grand then we put about 1,000 into it to get it sea worthy, it's a 1973 Starcraft Chieftan Mark 4 and shows it's age. are new 1 is a 1984 Imperial VC 230 that is in very good shape. I used to have a pic of it on my other computer but, it crashed and I haven't gotten around to putting the HD in the freezer to get all the pics off of it, smacking it with a screwdriver may work 2.

Ad in a mag of old time chevvy parts:
We have every Chevrolet fuel pump in stock, ready for immediate shipment. Many applications used “dual action” pumps which have a vacuum booster for the windshield wipers.
1942-51, 6 cyl optional w/ vacuum 9126 $139.50 $25
1952-54, 6 cyl fuel only 9798 $59.95 $5.00
1952, early optional w/ vacuum 9803 $139.50 $25.00
1952, late-54 incl. 1953 Corvette optional w/ vacuum 9797 $139.50 $25.00
1955-57, all 6 cyl fuel only 4149 $59.95 $5.00
1955-57, all 6 cyl w/ optional vacuum 4138 $139.50 $25.00

But, the point is moot as you can use vacuum
from anywhere on the engine, they used the fuel
pump because it was a constant supply regardless
of intake manifold vacuum changes
Suggestion: IF you want a constant vacuum supply
where the wipers don't slow down upon acceleration,
then use a Vacuum cannister setup similiar to a
power brake booster or cruise control unit (Vacuum tight coffee can)...

Thanks Streets, how do I hook the coffe can into the vacume line?

Looks like that boat has been sitting there for a while. Time to retire it to the junk yard or slap a for sale sign on it.

Or are you one of those families? You don't want to be one of those families.

Were going to sell it, it's not staying there forever.
