Fix for a Leaking Briggs & Stratton Gas Cap 799585

Here is an easy fix for a leaking Briggs and Stratton gas cap (799585)
Instead of replacing the cap which many have said leaks again, my fix was to replace the O-Ring on the existing cap.
I used a Buna-N O-Ring that can be found at your auto parts or hardware store. The size I replaced mine with was an 1.25” ID x 1.50” OD x 1/8 thick. Once the O-Ring was installed, I coated it with a little WD-40, perfect seal no more leak!

I was ready to trash my Toro Timemaster and replacing the gas cap O ring fixed the problem!
I was told to replace the entire gas tank, but, I decided to follow your advice and now I don’t have the gas leak anymore!! 👏👏👏👏👍
Thank you so much Sr.!!

That’s the issue I have and that’s exactly what I thought!
But, you made it easier for me.
Thank you

Thanks for the tip. I found the o ring at a Menards store and it fixed my leaking gas cap.

I actually took mine a step further and bonded a jet ski gas cap inlet with some JB Weld to mine to have a normal screw on gas cap. Just make sure to drill a tiny hole in the cap so it cap ventilate. www.amazon.com/Aftermarket-Kawasaki-Gasket-59231-3734-51049-3714/dp/B08J8F96JB/ref=sr_1_28_sspa?crid=J4GCJ5POBAZN&dchild=1&keywords=jet+ski+gas+cap+kawasaki&qid=1632158552&sprefix=jet+ski+gas%2Caps%2C174&sr=8-28-spons&psc=1&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUFUVEU0Tko1UEdHVkgmZW5jcnlwdGVkSWQ9QTA1ODA1NTZDTzlKU0k2NllPN0ImZW5jcnlwdGVkQWRJZD1BMDU3NTk5N0I0UFVFUjFEMklVMyZ3aWRnZXROYW1lPXNwX210ZiZhY3Rpb249Y2xpY2tSZWRpcmVjdCZkb05vdExvZ0NsaWNrPXRydWU=

Your welcome...I took this a step further. I took a jet ski filler neck and cap, cut off the existing filler neck on the mower and epoxied it to my tank. Now I have a "real" screw on cap. Thing to note, you need to drill a tiny hole in the cap so the tank gets vented. I'll take a video at some point and post it. Been running this was for a few seasons item I purchased is here www.ebay.com/itm/254698467094

Here's my latest video czcams.com/video/cyvqfzXkgxU/video.html

Leaking gasoline, gasoline vapors or both? I can smell gasoline in my garage. It's not coming from the carb (mower starts on first pull) or the fuel line (which I replaced anyway). I can find no visible fuel drops on the mower deck. Just ordered another cap to see if it solves my issue.

Brilliant tip. Thanks heaps 👏👏🌈😀👏👏

Where did you buy the seal?

[@zipstuff]

Home depot in the plumbing Aisle. Look at my other video as well for putting in a totally different cap

The reason that your cap leaks is so that it can breathe, very poor engineering Toro.
