Dumb Question

[JMIV]

So dumb question, I broke the OEM plastic fuel filter cap on the top side filter so i got new billet alluminum caps for both the fuel and oil filter. My question is that they come with an 1/8 outlet on the top side, should I teflon tape these or is that too much heat for tape? Pipe dope w a teflon additive? Any help is appreciated. Thanks Guys.

There is no such thing as a stupid question. I don't see a problem with teflon tape since I used it on my coolant filter.

I dont think you are suposed to use teflon tape around diesel fuel, not sure why but someone else will chime in and say why. Dustin

I'm running both the billet Fuel and Oil Caps, and I used liquid teflon sealant.

I've read the tape will be desolved by diesel fuel, but I haven't seen an issue with the liquid stuff I used.

Another thing, does anyone's billet oil cap seem shorter than OEM? By seem shorter I mean it is shorter. But seemed to thead in and seal up fine. Just amazed at the size difference.

I used teflon tape on mine, which was recommended by one of the guys at BPD.

There is a yellow teflon tape, which is safe for petroleum use. I havent used it on the truck yet, but used it with petroleum based stuff at work and it does fine. The liquid stuff mentioned above works as well.

Whos oil cap are you using?

The unit I have, looked about right. Remeber it's not just about the threads, and the caps seal, you need a cap that is going to properly seat that filter into the base.

When I build fittings and such for work. (Oil and gas well testing supervisor) I use light green teflon tape. It is good for petroluem , oxygen gas etc..
