Hi Norm and Mf
I can't even get the clear silicone to seal oil ,when I look up the specs it says the clear silicone resists oil but it's not oil resistant,
The black silicone works fine for me for sealing oil and the specs are it's oil resistant .Both don't mention being fuel resistant.
Silicone can .work very short term for sealing fuel but when I see clear silastic on parts that are in contact with fuel or on sumps and rocker covers it never lasts well.
When removing silicone ,I always wash the silicone in fuel and it orange peels and breaks up.
What about when you need to open it again? Do you have to remove all the old silicone and reapply?
I don't think there would be a problem removing the silastic it should fall off in a fuel / oil environment.
A good test although a little dangerous would be to put silicone on a leaking fuel tank ,it won't take long for the tank
to be leaking again.
Cheers
Max.
