FBaggshorses 3 #1 Posted May 20, 2021 In an attempt to remove the fuel line from the petcock on the bottom of my gas tank on a C-120 I inadvertently pulled the entire grommet out of the bottom of the tank spewing gas everywhere. Yes, in hindsight I should've emptied the tank but figured closing the petcock would be suffice... Wrong! What a mess.. had gasoline everywhere. Anyhow my question is: Is it necessary to use a sealant on the grommet prior to re-installing it back into the bottom of the gas tank? Oh and advise very appreciated thanks in advance.

bc.gold 3,399 #2 Posted May 20, 2021 (edited) No sealant required., Install the grommet first then the petcock, liquid soap helps. Edited May 20, 2021 by bc.gold 5 Share this post Link to post Share on other sites
roadapples 6,981 #3 Posted May 20, 2021 Don't use a grommet over. You can get a new grommet and shut off for 10 to 15 dollars... 7 Share this post Link to post Share on other sites

One thing, did the grommet come out in one piece, or did it break, there may still be part of it inside the tank. I have always found gas a good lube for rubber suspension bushes etc, it evaporates quickly, grease doesn’t. 1 1 Share this post Link to post Share on other sites

Maxwell-8 4,270 #8 Posted May 20, 2021 Like Dino mentioned in my topic, always use a lubricant when installing.It's easier to install but mainly easier on the grommet. 2 Share this post Link to post Share on other sites

clueless 2,898 #15 Posted May 20, 2021 (edited) If it's the original grommet that make it at least 44 years old, buy a new one with the valve, cheap fix, might make it another 40+years. Since the tank is empty remove it, simple, and rinse it out with a little soap and warm water, lay it upside down in the sun for awhile, with both holes open it won't take long to dry and the sun will help soften up the tank. Take the valve and put a little lubricant on it, preferably petroleum based, I use a little 3in1 oil, I use the s**t on everything #OLDSCHOOL, now push the valve half way into the grommet now put a small amount of the lubricant on the end of the grommet. Start the grommet in to the tank, once it's started push the valve in and it all slides in, easy peesy. Old Wheel horse mechanic show me this, works every time.
