Why We Sump Fuel - SPC Day 4

[@janklitzke2624]

Another great way to tell if you have Jet A mixed in with your 100LL is to pour a little bit out on a paper towel. If it’s pure 100LL it will dry within a few minutes and there will be no residue, but if there’s Jet A mixed in it will leave an oily residue on the paper towel which will not evaporate. Saw this in an AOPA ASI video the other day :)

[@WX4CB]

another way i beleive is rub it on your hand and you'll get that oily feeling on your fingers if there's jet-a in there

[@JustPlaneSilly]

Drink it!!! Only way to be sure.

[@priyeshkumarmistry]

Loving the series... Its teaching me a lot as a student getting his ppl.

[@MzeroAFlightTraining]

Glad you are enjoying the series!

[@grantmcasey4134]

Ok now I’m going to properly look at my fuel when I drain! Love this series so much!! Thank you Jason!

[@MzeroAFlightTraining]

No problem! Glad you enjoyed the video!

[@JudsonCc514]

"How are you enjoying the 31-day safer pilot challenge?" Well, Jason, it was fine until you did the side-by-side with the 100LL/Jet-A mixture. I had no idea how similar they were! Off to live in a constant state of paranoia now...

[@MzeroAFlightTraining]

hahahah sorry my friend!

[@reccecs4]

They're not similar if you smell. Or do a paper towel test. The nozzles are different between the fuel types. It would take a combination of a fueler who was very determined to make a mistake, a pilot who didn't ensure the correct refueling of their A/C, plus failing to detect it on the preflight. A fairly unlikely set of compounding errors compared to the real killers...

[@Pip2andahalf]

Could you elaborate on the paper towel test please?

[@reccecs4]

Soak a corner of a paper towel in the fuel. Jet A will leave a visible ring when the avgas evaporates.

These are super great short videos!!! Thank you 😊

[@SmittySmithsonite]

My 1st time ever seeing Jet A fuel. A very light straw color compared to regular pump motor fuel at the local gas station. Jet A and 100LL mix like gasoline and diesel, only it's the diesel that has a bluish green tint to it. Back before MA mandated a percentage of biofuel in kerosene and dying it red, it had a very light straw color just like Jet A, maybe even lighter. Interesting stuff nonetheless. As a mechanic, I'm constantly elbow deep in regular automotive pump gas. I get many, many examples of water settling to the bottom, thanks to the mandated ethanol content these days. It soaks up moisture like a sponge. Here in MA, we can't get any ethanol-free fuel at any pump anywhere in the state. God forbid they let our outdoor power equipment run correctly, and make it through storage without a carb clean. But I digress! Great vid, Jason - much appreciated.

[@davidpinon2070]

I feel for you, spilling some on 23MZ, but THANK YOU for this video!!! Have a blessed day.

[@CSTNKTAP]

Really nice series! For a moment there I thought that you would ask us to taste it haha!

[@MzeroAFlightTraining]

Thanks for the feedback! I'm not sure we have the palate for that haha

[@andyk295]

Thanks Jason ! I'll keep an eye out since KVNY has both Jet A and 100LL fuel trucks.

[@AkPacerPilot]

Something that happened to me that you should be looking for. Debris. I fueld up once, right after another plane left the fuel pit. I fueled up, shot a sample into my test bottle and there was a bunch of tiny gravel. Out of concern I called the service number on the fuel pump and the owner told me it happens often. Guys will push off spin the plane, fire up and blast gravel. Causing gravel to blow into the open nozzle. At that point I was glad I was taught to sample fuel prior to putting it in the tanks. I could only imagine that it wouldn’t take much to plug up a carb jet, if the sump screen didn’t catch it.

[@SmittySmithsonite]

I've seen barely visible particles cause motorcycles, and all kinds of outdoor power equipment to become a no-start. The idle passage is the smallest of them all, and is needed for starting. Very easily choked off.

[@moonshiner5412]

I've always said, "Nothing like the spell of Jet-A in the morning!" Worked flight line with F-111's at Mountain Home AFB in early 70's. Spent my career as software engineer on AFB with ability to catch a quick smell from the planes on nearby runway. Actually, it had not been pointed out to me that it would always be blue! I have been looking mainly for water. I will now put against the white of the plane. Thanks!

[@MzeroAFlightTraining]

Thanks for sharing! Glad you enjoyed the video!

[@kurtreber9813]

JetA isnt blue

[@fdcap9835]

The 172R I fly has 13 sumps! I carry a towel and some "wet ones" with me because it's not possible (for me anyway) to sump all these ports and not splash something on myself!

[@flygirl6048]

Goodness sakes! 13?! Are you supposed to sump the tank dry??

[@wmayo1492]

Love the videos-topics explained concisely, but clearly. Videos always well composed and edited. Ordered the book, too.

[@MzeroAFlightTraining]

Awesome, thank you!

[@drcode4]

I totally thought mixing the Jet A and 100LL was supposed to cancel the blue color of 100LL. Thank you for that demonstration. I will be much more careful while sumping now and will use the smell test. Thanks again!

[@jerrywong2091]

Keep those safety tips coming. I learned something today. Thank you

[@paulamunoz6796]

Thank you Jason!, your videos are always so helpful😊

[@hughtillman9521]

Sniff test!! Perfect. The mix of Jet A and 100LL is unlikely but if it happens I’m not sure I’d catch it. Thanks Jason.

[@flyboy7981]

I love the series 😍 can't wait to watch the next episodes. Great idea you came up with, Jason!

[@MzeroAFlightTraining]

Glad you enjoy them! Next one coming tomorrow :)

[@JoseRivera-lt2cc]

Good stuff. Wasn't aware of mixed JetA-100LL distinctions. Learned something new today.

[@PiperPilot1976]

4 for 4! This was a good experiment for the beginners! i may play with this as well at my local airport.

[@markfacer2296]

Great series! I had to drain water from the fuel before flying a 172 to Houston from Kissimmee a few months back! Not a comforting feeling! Sump sump sump, drain drain drain...repeat until there's not even the smallest trace of water at the bottom!

[@John170B]

[@MzeroAFlightTraining]

Thanks! Will do!

[@ChrisSmith105]

Don't worry about the messes too much! Worth teaching all of us the differences.

[@t0eknee959]

This is actually one of my favorite things to show non-pilots when I fly them. Sans the jet A. But we always have a water bottle around to show them the fluid separation and why it’s dangerous.

[@MzeroAFlightTraining]

I agree, it is a great demonstration!

[@SmittySmithsonite]

Yep, water goes straight to the bottom - right where the fuel line pickup is, sending it direct to the metering device (carburetor or FI).

[@jameswebb2912]

Got it. Question: What do you think about using a sump bowl that has a filtered orfice for returning the check fuel back into the tank?

[@skesno309]

What happened to Ashley?

[@stratalysjeff]

Uh that was exactly what I was wondering. Doesn't Jason have 3 kids with her?? I also got the sense he was an evangelical. Not saying there's never been a religious dude that got divorced, but I'm a little surprised here.

[@skesno309]

@@stratalysjeff Me too but. I quit following the channel for several years so i'm out of the loop. Just recently started watching them again.

Jason’s personal life has been quiet for several years to allow healing and respect from a long divorce. Several years have passed and both have restarted their personal lives with wonderful people, independent from each other. We are thrilled to share with you Jason’s growth, both personally and in aviation. Thank you for your support and love for aviation.

[@Neilazbiker]

Good example. Thank you

[@HiddenWindshield]

At 1:19, I would have said that the cup on the right was the 100-LL, because it's a lot bluer than the other two. Was that deliberate? Were you trying to illustrate how much the background matters? Or did you just not think about the background when you planned your camera angles?

[@pilotrussell1755]

Series is awesome!

[@MzeroAFlightTraining]

Thanks Russel!

[@mikezaq1]

If you look at the color of light coming through each glass straight 100LL vs 100LL mixed with JETA there is a clear difference in color visible in the light coming through the glass and shining on the elevator. The light from the 100LL mixed with JET A looks yellow while the straight 100LL looks blue. While you should know by heart the color of 100LL looking at the color of light passing through it is another way to tell if you might have a fuel mix-up.

[@mondodrum1]

awesome..........I fly drones but this stuff is fun.........Happy New Year

[@MzeroAFlightTraining]

Happy New Year! Thanks for watching!

[@roberthblanchard]

Interesting! Density difference between the fuel and water makes it separate. Two fuels must be very similar density or haven't allowed enough time for it to separate. Smell test!! Haha love it

[@solgoode1]

You guys are great!

[@golfbravowhiskey8669]

I was waiting for it, the sniff test. I was hoping you were going to do it. About 15 years ago I smelled it on all of my 152s. The ramp guy finally admitted to putting in 4 gallons of it before he realized what he had done. And he did not say anything, when I sumped The tank smell like diesel and I knew what had happened.

[@richardburton6182]

Blindfold taste test, like the old Coke v. Pepsi commercials. 9/10 people prefer Jet A!

[@joro18d93]

Love this vid. Easy to distinguish each cup. Jason, I'm curious. You always wear 2 watches. Tell why in a new video please. Just curious.

[@MzeroAFlightTraining]

Hi! Jason wears two watches because one is in local time and one is in Zulu time! Thanks for watching!

[@salty2561]

You didn't say in the video but is the mix bad for the engine? Should you just leave the plane and get a A&P to drain the tank and fuel system?

[@christophers5664]

I like the new intro music.

[@ytoal]

gravity test also with an Avgas hydrometer

[@EricCullum]

The Specific Gravities are: 7.4 lbs/gal for water, 6.02 lbs/gal for Jet A and 100LL fuels. Of course this is for Standard Temp and Pressure. That's why the water settles and gives you an idea on how Shooter drinks and Black and Tans are made. 😉

[@sebastiangoddard4518]

Scary how similar the mix looks!

[@MzeroAFlightTraining]

You got that right, thanks for watching!

[@rafborrero]

Lol, Magda looked so excited to show us the sumped fuel...but he panned the camera away!

[@MzeroAFlightTraining]

hahahah my bad

[@robertlafnear4865]

One would hope that the fuel suppliers make no mistakes when THEY load or transfer the fuel,... 'cause it says 100LL might not be true or JET A......I found a regular gas station that loaded some Premium gas into the Diesel ground tank............ and I bought a full load of Diesel on an early morning fuel up......... just glad I was not in the air when I switched tanks........Always thought that the producers should have an additive that when cross mixed would turn a really odd color...... like the red + green make's yellow........ just my view. Always good to have a heads up reminder video,... Thank You.

[@salty2561]

I delivered fuel before; that happens more often than you would think. Co-driver put 1000 gallons of diesel in a premium tank once. Cost the company over $10K to fix it.

[@CarlosRodrigue183]

[@karson8292]

after you fuel how long should you wait to sump?

[@christiannoble5140]

After 22 years as an ABF (Aviation Boatswains Mate Fuels) in the Navy I can say without a doubt I like the smell of 100LL better than JP-5 which is the same color and smell as Jet-A with a higher flash point. That smell is difficult to get out of your clothes.

[@PaweUrban]

Would be good to show to people how does the MOGAS look with water in it and why it's not as safe as AVGAS.

[@publicmail2]

I was under the assumption if AV gases where mixed it was engineered to turn clear, maybe JetA not included?

[@SmittySmithsonite]

I don't think they're engineered to do that as far as I know. It will happen naturally with enough of either mixed in. Same with gasoline and diesel. Diesel has more of a greenish tint mixed with the blue.

[@2flyAustria]

Why do you wear 2 watches?

[@MzeroAFlightTraining]

One watch is for local time and one is for UTC (Zulu). Thanks for watching!

[@jeshua04]

The only way to know the difference is by, of course, drinking it!

[@ErelasInglor]

This is why my instructor always said to give it a whiff and make sure it smelled the same...huh. Then again, I've never smelled jetA fuel to compare.

[@lucky_one2]

Nice intro!

[@louisemateos2443]

Also, either refuel yourself or monitor the person/people who do! Jet A nozzle is different than 100LL.
