I quit with thread tape years ago on cars. I use Permatex thread sealant now.

I picked up some fuel line rated tape at lowes to prevent leaks on my harbor freight fuel pressure guage. It worked well. Right next to the regular plumbers tape, but it's yellow. Make sure it's only on the threads, you don't want anything getting pulled into the filter and plugging it up.
Working in plumbing we use monster blue teflon tape. Also grey one is good as well. Says it's good for a lot of chemicals and fuel.
White is cheap and yellow was for lp or gas. We also had pink but never used it since the grey and blue was professional and covered all we needed it for
White...yellow...blue...grey...plaid...infra-red...ultra-violet...MAKES NO DIFFERENCE.But, keep this in mind. "Gas Rated Thread Tape" has nothing to do with gasoline or any normally liquid fuel.
It only applies to actual "gas" like Propane.
And forget about plumbing tape entirely... ...Tape? no nope never
TRUTH! Teflon/PTFE tape has NO business on an automobile, ESPECIALLY in the fuel system or oil system.I quit with thread tape years ago on cars. I use Permatex thread sealant now.
I think people dont really understand how durable teflon tape is and how far it will stretch while still making its way through your oiling system.White...yellow...blue...grey...plaid...infra-red...ultra-violet...MAKES NO DIFFERENCE.
The **** is all the same--PTFE is Teflon but without the DuPont brand name. It's all resistant to the same chemicals. There's two differences, and neither one is important.
1. Some tape has a colored dye put into it. The stupid color becomes a registered trade-mark that no one else can use.
2. Some tape is thicker than others. Saves two seconds of winding more tape onto the threaded fitting.
ALL of those Teflon/PTFE thread tapes are a friggin' disaster. If it doesn't shred when you screw the thing together, it'll shred when you take it apart. All the little strings of shredded tape then contaminate the system. The best--and perhaps only acceptable use of thread tape is on pre-threaded iron pipe for compressed gasses--fuel gasses or merely compressed air. The Chinese pre-threaded pipe and fittings are threaded so rough that a typical liquid sealer can't fill the enormous gaps between the threads. Not a big surprise that the leading retailers of pipe tape source their product from the same country building the defective pipe!

But "Permatex" makes many different formulations of "thread sealant", and at least one of them is pretty pathetic--the common one sold in a brush-top plastic tub.
You're looking for the "PST" versions, #565, #567, and/or #592. 592 is the easiest to source, and not as expensive as 567. VERY recommended. Sold as "Loctite" or "Permatex" depending on the market.
Yep, tape is bad.
But, more importantly, before you burn down home depot in a fit of rage,
take a look at how different types of pipe and tube and fittings work.
Some types like "NPT" are a tapered thread and are cut very differently than other types of thread.
Some types of thread are designed specifically for the use of thread tape.
Others are designed to never use thread tape.
Most of the time people jyst crank a buch of random **** together with no idea about the difference between thread types and then pack that **** full of tape
and blame the tape.
Kinda like my Ex, just cuz it screws together dont mean it goes together.
Do some deep Google save yerself some leaks
They are threaded in differdnt ways and thd ID/OD are measured in different ways.
This also applies to the difference between "pipe" and " tube"
This is why 1" pipe is not 1" in diameter,
but 1 " tube is 1" inch diameter.
Its all a bit of arcane nuttiness but well worth the look.
Understanding pipe sizes and thread types will really cut down on aggravation for the rest of your life.
And will allow you to go to Home Disaster or Blows, grab yer **** and get the hell out.
They should teach it in school
I can't find a M16X1.5 Male or female to barb that come with an "o ring seal", other than female pair at Leroy Diesel which is $28 after shipping. I need one female and one male. This is to be used behind fuel filter only (at LP) on a 6.5l K3500. Could these tapes be used as a substitute? The goal is to avoid leaks.
