The time has come to replace the Winn fuel filter with the Racor system and I need to learn the best thread sealant for use with diesel. Thanks!
The label on the product should tell you if it's resistant to diesel fuel.
I wouldn't use Teflon tape for your application.
Amazon.com: Gasoila Soft-Set Pipe Thread Sealant with PTFE Paste, Non Toxic,... (https://www.amazon.com/gp/product/B00207KC5E/ref=abs_brd_tag_dp?smid=ATVPDKIKX0DER)
Same, Gasoila. I use it all the time at work and it never leaks.
Check shelf life!!
Gasoila, good stuff.

Thanks for the prompt responses. I found Gasoila at my local Tractor Supply Conpany and will use it.
Seems like all the fittings on the racor that replaced the Winn were either o ring boss or flares, no sealant necessary on these.
I recently did the same pre- fuel filter switch and used GASOILA.
Follow up question: I assume the fittings on the Winn system and the Racor system are the same, and I now see that the Racor system uses straight threads and O-rings. Can I assume that the fittings on the Winn system are the same? It appears as if the fittings on the Winn have an adapter between the filter and fuel lines, and that the fittings on the fuel lines are tapered pipe fittings and would require the thread sealant.
