Use of Teflon Tape on fuel fittings
OK, so I have done some more research on the subject. The Product I used, Retorseal T plus 2 is not a good way to go. <sigh>
The diesel rated product for long term exposure is Rectorseal No. 5. Same process for application, it is pressure rated to 350 psi of diesel with no leakdown after 720 hours.
As mentioned by others, the manufacturer sayes the Teflon products will have their carrier desolve over time, and then eventually leak. Not to mention all the teflon particals that will clog your filters.
I will be taking the system apart over the winter and clean and replace all the fitting''s coatings with their diesel rated product.
