Fuel-Proof Thread Sealant... Suggestions?

[Double12]

I need some good fuel proof thread sealant made for parts constantly immersed in gasoline (such as the threads for the o-ring fitting on the AFPR). I'm hesitant to use high tack, though it claims to be resistant to gasoline. Any suggestions would be greatly appreciated.

TIA,

Dan

That fitting should not need thread sealant. Something else is wrong.

I use a little silicone grease on the o-ring. That's it.

I'm speaking of the o-ring fitting to the fuel rail which I had to remove and machine due to some clearance issues... I would assume you are talking about the return line fitting?

The return and supply side both have o-rings and should not need thread sealant. NPT fittings should have sealant, and the teflon paste resists gasoline. Extreme care should be taken with any sealant used with the fuel system to prevent contaminating the injectors.

HTH,
