5613 Vacuum/Pressure Gauge Kit with Storage Case | Test Vacuum Lines, Low Pressure Fuel Systems & More - Quickly Diagnose Problems like Bad Rings, Valves & Leaking Head Gaskets

The large gauge is easy to read and it's accurate. OTC makes great tools that are used throughout the automotive industry from dealerships to gas stations. I've never had a problem with OTC tools in my thirty years in the field. Highly recommended.

Good tools. Works great.

This is a must-have for any mechanic's tool chest. Whether you are tuning up an old Mustang or troubleshooting a new Honda, a vacuum gauge is indispensable. My kit included: -One 3/1/2" Vacuum gauge encased in rubber--this thing is heavy duty -One 24" hose -One in-line barbed connector -One Fuel Line Universal Adapter -One "T" barbed connector -One conical nozzle adapter The gauge also reads both vacuum and pressure Scale reads from 0-30 inHg, 0-70 cmHq, 0-15psi, and 0-100kPa How does it work. By getting a good vacuum reading (generally off of your vehicle's intake manifold), you can tell a lot about your engine's health. there are some great YouTube videos on how vacuum/vacuum gauges work, but here are some basics (engine idling and warm): -Most engines read between 16-22 inHg. This should be a steady reading once the engine is warmed up -A reading of 8-14 inHg that is steady could indicate a small vacuum leak, a slight timing issue, or poor compression -A reading of >22 inHG that is steady is most likely a timing issue -Small intermittent drops are caused by a problem with the valve spring or a sticky valve This list isn't even close to being all inclusive and doesn't even go into non-idling vacuum diagnostics. There are plenty of online resources for more information. Bottom line is if you have the skills to at least change your own oil, you can benefit from using a vacuum gauge. This gauge kit is durable, comes in a great sturdy case, and has a large easy-to-read gauge face with a handy. I would recommend this to anyone with a rough running engine or a home hobbyist who likes to keep their car in top condition.

Good quality a must have when setting carbonated engines.

The first gauge I ordered from Amazon came reading 4" of vacuum out of the box. I hooked it up to my MityVac pump and confirmed it stayed at 4" off throughout it's entire range. I was disappointed. So I returned it for a replacement. Amazon handled the exchange quickly and with zero hassle. The 2nd gauge to arrive read 0 at rest, and stayed right on track with the MityVac pump through it's entire range. Ahh, much better. So far I have only used this on 2 cars, and they have both had excellent readings with very steady needles on the gauge, so I cannot say it has actually helped me diagnose anything other than properly tuned vehicles, but I am certain it will come in handy one day and I like having it in my tool collection. My only minor complaint about this gauge (other than the questionable quality control on the first one I received) is that I would have liked the case to have been molded a bit differently. While it is plenty large overall, the way the recesses are formed for the gauge and hose means you need to disconnect the hose from the gauge to really get it to set in the case properly. It would have been nice if there was more clearance molded in to allow the hose to stay connected to the gauge and allow for nice gradual bends instead of sharp creasing bends. As I said it is a minor complaint, overall this is a nice gauge.

Great vac and fuel pressure gauge. Works well, OTC make great tools, good price and good quality and good delivery with no problems, honest dealer thank you

YAY, mine didn't come out of calibration amd reads perfect at zero when not inuse. I needed to replace the one I had after letting it drop into my radiator fan (different brand/from parts store)! Cool that it does fuel pressure but I already one of those, so this is only for vacuum. Which is a must for a 72 C10 Chev Quadrajet idle mixture tuning! It is also larger than my replacement and best of all it has a bracket for hanging it up - perhaps now I'll not let it drop into my radiator fan! With it bigger and able to easily hang from my hood - it is so much easier to read. The storage box is a plus too, though I guess it is just one more box I have to figure out where to store. 1st world problem that is ha!

The OTC 5613 Vacuum/Pressure Gauge Kit is an indispensable tool for accurate engine diagnostics. Whether you're troubleshooting vacuum leaks, fuel pressure issues, or HVAC performance, this kit delivers professional-grade results without the shop price tag.

Box and Black plastic Case Damaged Zero keeps changing its place. Zero cannot be adjusted having wrong reading. I purchased because it is an OTC product Not satisfied.

The OTC gauge measures approximately 100mm in diameter including its protective hard outer plastic shroud which I’d like to see a little wider to absorb any real world knocks..It has a clip attached at the rear for hanging the gauge and with the clever use of a Blue colored face and White markings and dial, it makes this combination ideal for reading both Vacuum and Fuel Pressure on the one convenient gauge..It comes neatly arranged in a suitably compact plastic carry case to protect your investment. Inside It also contains a 600mm rubber hose and a plasticTee piece, a hose to hose joining piece,a plastic adapter and a metal fitting to make connecting the Vacuum gauge easier.Whether these fittings are suitable for fuel,I have not tested that yet.The Vacuum and Pressure gauge reads primarily in Imperial on the outside and Metric on the inside, just the way I like it! Vacuum reads 0-30 inches of Mercury in 5 inch increments and one inch finer markings in between for precise measurements and O-70cm of Hg in a similar incremental layout. Pressure primarily reads from 0-15psi in 5 psi increments then more precise 0.5psi markings in between and 0-100kPa reading in increments of 20kPa and finer 5kPa increments for more precise readings.The pressure scale could be used to read fuel pressure on older vehicles with a mechanical /diaphragm fuel pumps.The only thing a little annoying is the gauge rattles a little but easily fixed with a small daub of plasticine between the gauge lens and the shroud .Overall ,OTC makes a reliable and accurate gauge that any professional mechanic or technician would want to own and at an affordable price.

Works good, seems to be of good quality materials. My only complaint is that once the hose is attached it's very difficult to remove (that part is not my complaint!), and the only place to put the hose is in a small cutout underneath where the gauge lies, meaning you have to precariously coil up the hose, place it in it's spot, run the remaining hose in it's little groove, and place the gauge back on top without upsetting any of the hose (it's a challenge!!!). Not a huge deal, just a minor annoyance.

Muy bueno, para revisar vacío, buena calidad

Gauge is massive very easy to read! At half the cost as the exact same mac tools model. The case is very rigid. Cant go wrong with otc quailty
