A LOOK INSIDE A NON SERVICEABLE VENTED FUEL CAP

[chrisssmallengines]

Great video, love to do things like that myself . You never stop learning, or thinking .

Good stuff, thanks for showing the internals of the gas caps and how they actually work.

Good sound effects. I'll never forget what a duck valve is from now on...lol
Loved the video!!!

My fuel cap story...Late December 96...Bosnia (NATO not UN). I had a 10K GenSet (DED) that kept running out of fuel. Kicked my butt for weeks (no support no parts). I couldn't figure out why or how until I was holding/fiddling with the fuel cap cussing and carrying on trying to figure out why...I noticed the center pin wasn't 'springy''...I replaced the cap and BOOM goes the Dynomite! Victory! Crazy how we can't see the forest b/c all the trees are in the way. My fuel cap story

Cool, I just ran into the "non-venting" gas cap and was wondering about these type caps, no pinholes. I have never had this issue before I took apart my carburetor three times. Then finally, I figured out it was the gas cap. And to add insult to injury, this is a new tank, I replaced it this season. The old one had a leak. And I was doing my normal spring maintenance stuff. Started right up sounded good, started mowing and it did the sputtering thing. Of course, the first thing I thought was I did something wrong with my carb cleaning. After the 3rd time, I searched the internet and of course all it said was carb stuff. After a day or so of searching, I finally ran into the mention of the gas cap. I said no way, it's freaking brand new. After doing the simple fuel flow test, low and behold, it's the damn gas cap. Luckily, I didn't throw out the old tank, yet. I put the old cap on it (15+yrs old) and no more venting issues. But the old one is beat to hell on the inside & the new is...well new. It's for a Briggs & Stratton engine. That's what I get for buying a generic replacement $36 vs. $56. But damn $56 for this gas tank...SHEESHED. LOL

Good to know. I wonder if putting a non functional cap into an ultrasonic cleaner would be helpful.

TY just this past week, I was wondering what the caps look like on the inside & how they work.

I have a Crapsman Lt1000 riding mower. After running it 10 minutes it shut off. Ill restart it and it will fire up for 2 seconds then die. I can do this till the battery dies. Ive tried 2 different carbs from Scamazon but the same result as mentioned above. I ordered a new gas cap, hoping this will fix the problem

I am sure that this video helped some people. Thanks.

Great video. Correct me if I'm wrong, but isn't that vent system not so much a tank vent but to maintain that tanks fuel pressure to those levels. Wouldn't a tank vent have the duck bill the other way around?

[MonitorOpsandExotics]

How do you know the gas cap is bad? I have a bad boy mower and it’s not pulling fuel from the side with the blade controls and ignition but it pulls from the opposite side. This just started happening.

@THEMOWERMEDIC1, This is unrelated but where did you train to be Stihl Certified or let me ask do you know if they offer courses in West Virginia, I'm working at Greater Huntington Park & Recreation. They chose to go all Stihl. Just asking.
Thank you. JD

From my own experience that check valve ( Vinton or neoprene) will get chewy and soft from fumes over the years and will almost glue itself so it won't open or aloud air coming in. You clean it and only will solve it temporarily. Better replace it.... good job #mowermedic1

I received my new tank today and I remove the duckbill. I all drill extra 1/8 hole. I need to always breath as auxiliary tank.

[marshallborder]

I probably would buy a new one also, they don't make that plastic too take apart most the time .

[timjones]

Hey mm1, any chance of a sticker for my collection?

[ncrdisabled]

i think they should make them all severable.
