Skip,

I see you are using A type of plummers tape Teflon. I hope this will withstand being exposed to the fuel and have you had any trouble with it leaking?

Nope, should I worry? Been using the same roll of tape for ~5 years on various fuel systems (and plumbing ). You must start with nice dry surfaces or it doesn't work so well. I've tried to find something more suitable locally, in vain. What do you recommend?

From my experinces working with teflon tape at a propane company, if you dont do a very careful job applying the tape, pieces can come off and work their way into the system. I would recommend that you look into the liquid version of the teflon thread sealer. Just my thoughts on the subject. We use both the liquid and the tape and the only reason we dont go over to the liquid exclusively is cost related.

Thanks for the info. I'm concerned about the actual material and any cause for alarm by using this in a fuel system. I am always careful not to leave dangling bits and never cover the very ends of the threads... and always get a dry application. I have heard stories of injectors getting clogged with teflon, but that can be avoided with proper application. The few references I have found from fuel rail manufacturers say to use Teflon tape, liquid, or medium loctite... but to keep it off the first thread or two (due to the cutting action when installing the nut). When looking at liquid Teflon laced products, I do see a distinction for fuels like gasoline or kerosene... but no such thing for the tape. I have seen a few references for it not to be used in Diesel systems.
