Great product, however one must be careful not to over tighten the screw on lid. I must have done that because mine split down the side of the cap.

Works as one would expect. Easy to see water and contaminants. Great for those states where pouring 100LL on the ground is a crime.

GATS JAR FUEL TESTER 16OZ

Fuel jar allows for taking large samples which is good for removing debris from tanks. Easy to clean out if there is contamination, such as water or paint chips. Other testers are difficult to wipe out.

This hands down amazing! I was dealing with drips from my sample ports and I noticed some contamination in the old non-GATS sampler and figured I should try GATS to catch and remove the contamination. Sure enough, GATS caught a bunch of crap! I choose not to throw out samples and this tool makes it easy! Excellent product!

Thumbs down. Only 5 star reviews go on top so beware - 1 star review here - these are such poor quality Compared to the older ones. A year of use and the o-ring has failed, the thin walls have buckled and its so sad that they no longer have the “spout” indent in the rim. Fuel does go everywhere unlike the original. I’m not bothering with trying to replace the o-ring, I’m going to find something better.

I am really happy with the gats fuel tester. Its nice to take a large sample especially when you do have contamination. It also feels good not wasting fuel and making a mess by dumping avgas on the ground. Yes the older one sounds nicer with thicker plastic and a pour spout, but this one works fine. Dont let that scare you away, this is the best tester I have used when fuel quality is concerned.

Great but I got the large jar and would get the smaller one next time.

A great product - easy to use and you dont get fuel on your hands!

By far the best Fuel sampler I’ve ever owned or used.

Great product

Exactly what I needed. Great product.

These fuel-testers work really well and save you throwing the sample away. Good for the environment, good for your wallet too! Highly recommended!

Awesome product: no fuel on hands, easy to collect large sample, and great filter. I purchased another for the hangar as a spare!

Very fast delivery from Spruce Aircraft for the Gats fuel sampler. Well made, easy to use and pleased to no longer be pouring avgas on the ground.

I decided to try this gats jar so I could reduce my fuel wastage and I am happy to say that I works just as advertized with straining the fuel. I havent had any water in my fuel to try that part out but am confident that will work as well.

Keep on in each plane that I fly regularly. RV6, C421 & C441

No mess, and allows you to easily see fuel color and contamination, if it is present.

Love my gats. Works as advertised. Mine disappeared so am ordering another today.

Well designed & love the features. My only gripe is the plastic jar is a bit flimsy

Im not sure what I expected, but the jar is larger than I thought it would be. I am so used to a tiny fuel sampler that it just seemed overly big. However, it is crystal clear and makes the visual inspection for water and contaminants so much easier than my old, cloudy fuel sampler. The screen is easy to clear out after returning fuel to the tanks. The jar came with a crimp/crease in it, no leaks, just a blemish on a brand new device.

Container is light weight plastic but unit does what its supposed to do. I would buy again.

O-ring wore out, I contacted the company and theyre sending me a replacement under warranty. No questions asked.

Does the trick, but the quality of the product has gone down significantly in comparison to former years. The clear plastic part is pretty flimsy...

The GATS jar is great and works good. Bought two for our flying club as replacements for old dirty damaged ones. The plastic used for jars feels thinner and cheaper. I am a little disappointed by this.

Container is a bit flimsy, thought I was going to warp or tear it when uncapping it. The rim isnt designed for pouring, i.e. doesnt have a lip that has a pour spout.

I tried to replace a lost Gats with identical unit. It is just like many others said -- the clear jar is now much thinner than before. I did not realize how thin the walls are until today when I used it for the second time. When I reached into the cabin, I found that the jar is deformed from just sitting just one afternoon in the cabin on the ramp. The jar was on the floor -- not up in the glare shield. Now the jar leans to side when sitting. I dont expect this purchase will last long.

This new version of the Gats jar is awful. They got rid of the indented spout in the upper ring, so now when you go to pour fuel back into the tank it goes everywhere. Additionally, the jar itself is now made with much thinner plastic. It feels like you could break it just by squeezing. I highly recommend finding one of the older Gats jars. Do not give this company your money for such a terrible regression in product quality.

Just got the new GATs Jar and it feels like a plastic water bottle its so thin now unlike the last 2 or 3 that I have bought for different airplanes. Like everything, they figured out a way to make it cheaper and less durable. I compared it to one I have had for years and what a difference.

The strainer assembly is cheap plastic that cracks easily. Mine has a crack running through the side from normal use. Now fuel can spill out the side. The clear cup is ok but others have mentioned it is flimsy. I would avoid this product since the quality is just not there for the price.

Im not happy with this jar. The length of the pin allows too much fuel to splatter out onto my hand. And when I go to put the inspected fuel back into there is no spout to direct the fuel and invariably some of it gets on the wing. The best thing about it is the filter screen. That does seem to do its job. But I am moving to another fuel sampler.
