A while back I replaced the fuel sending unit and gasket. Now it seeps fuel when the tank is full. Is there some sealant that I can use that is safe with gas. I thought that I had heard somewhere that silicone would not work with gas. Any suggestions would be helpful.
By the way, it had the same leak before I replaced the sending unit. The tank does not appear to be bent or tweaked in any way. I think its coming from around the screw holes, and yes they are tight.
thanks

Just my 2 pennies, I have used most all of permatex's products an I find that ya just cant beat the Black #16B, I prefer it over there Blue Glue an other products for its durabilty and Durometer it achives when it cures.
You can pick it up at any NAPA, just make sure to REALLY clean all your mating surfaces with laquer thinner or acetone..so THEY ARE CLEAN!..an let the Black cure very well at least a good day before puttin the gas to it an you will end up with a NO LEAK SITUATION!

Make sure its for use with gas lines, water, steam ect. I've had the best results using this type product for these kind of repairs. A little bit of it goes a long way. | | | | | Joined: Oct 2008 Posts: 88 Wrench Fetcher | | Wrench Fetcher Joined: Oct 2008 Posts: 88 | thanks for all the help guys | | |
