Walmart [walmart.com] has Equus 3620 Innova Vacuum Gauge for $9.97 w/free store pickup. YMMV

I had to call in to walmart support to get the price honored. If you search "innova 3620" it will show like $20.97. My link will show $9.97. When added to cart, it will change to $20.97. So call/echat or get it honored in store if your local store has it in stock. Just learned my store honors their online price now. My order was a ship to store as they don't carry it in store for me.

Again. YMMV.

Simple device used to diagnose engine issues. See DIY videos below.

You can diagnose: Restricted intake, Exhaust obstruction, Vacuum leaks, Incorrect valve timing, Sticking or leaking valves, Worn valve guides, Weak valve springs, Head gasket leak, Worn piston rings, Improper idle mixture

IIRC, Amazon had this for like $23 last nite. Now its thru 3rd party for about $28. And is rated 4 1/2 stars. [amazon.com]

Sears [sears.com]has it for $29.90 in the "paper towels" section. lol

This gauge is ONLY marginally useful if you have an ANTIQUE car.

The first fuel injected cars in the ~80's had higher fuel pressure 15 psi than this gauge reads which is 10 psi. Cars in the 90's have 50 psi and the latest cars with direct injection are over 2000 psi. So this gauge is worthless, I can't believe they still make a tool that was last used in the 1970's, it might be great if you live in Cuba!!!

Wow. So not only are you a troll, you don't know anything about cars also.

That's interesting given I've been racing since my preteen go-karting days and at one point was 2/10's off the national record in NHRA modified production with engines I built.

Here's what you should do. Check stock on this item, there will be plenty available at whatever WM you choose. Think about that. Buy this, and if you are at a WM that does oil changes, walk over to that department and ask anyone in that area what it is that you just bought.

Make sure to tell them that you have been racing since you were a pre-teen and have built many engines. Prepare to be laughed at by a WM employee. If you want to skip the part about being laughed at, look at the video links posted by the OP. For more advanced techniques, ask anyone at your local Jiffy Lube.

I guess you missed this part of the description: "Accurately checks system fuel pressure on vehicles equipped with carburetors"

So it doesn't work to check fuel pressures on modern fuel injected cars, but on the flip side, modern vehicles use vaccuum pressure to control various engine functions much more than older cars did, so having a gauge to check this can be very useful in engine diagnostics and getting rid of the cause of many of those engine trouble codes.
