Additional fuel filters

[pstephens46]

didn't have to - inherited it from previous owner;
a little surface discoloration but it will last forever,
despite being installed inches from the batteries - a nasty environment

but I could easily spring for this:

I know it has been discussed. What is the
pink thread wrap you used on this?

[grouper242]

Thanks everyone!

What is the pink thread wrap you used on this?

its "just" PTFE tape - the pink color is to identify it is "full density" - similar to the yellow.

A great deal of misunderstanding/misinformation associated with PTFE tape....

Is that full density or fuel?

[fairdeal]

Is that full density or fuel?

"full" - meaning that it "weighs" ~1.2 g/cc
yellow tape is about the same
white tape is often ~0.8 and "cheap" versions as little as ~0.4

PTFE tape is strange stuff, IMO
apparently the raw material can be "stretched" in manufacture
the yellow and pink have not been stretched: "full density"
but the white has been - creating "voids"

so although the thickness of the tape is the same, regardless of color
there is "less material" in the same length piece of typical white,
vs yellow or pink

building codes require only full density tape for piping used for gases
(natural gas, propane, etc)
and the yellow color is simply to assure that is what is being used

there is a misconception in some quarters that yellow tape is for "gas": gasoline
because it is somehow "resistant" - while the white is not.
Nonsense; they are both PTFE
and actually, the white is "pure" - 100% PTFE
the yellow or red - only ~99.5% PTFE
the rest is the pigment

Use the white tape on aircraft and at home for whatever all the time
..as a matter of fact I never even seen the colored stuff before!

[fairdeal]

I never even seen the colored stuff before!

there has been quite the proliferation in recent years

green - "oil free" for oxygen lines
(not that there is any oil "in" the others,
but apparently made using machinery that is not oil-lubricated
to avoid any possible "contamination"

and you can get added constituents to the PTFE
nickel, copper, ceramic

Very interesting...learning something new everyday. We use it on O2 systems on Aircraft and have a special set of CLEAN tools just for that work.
More than one airplane has been set on fire from people using greasy wrenches on O2 systems.

Good info Mr Fairdeal. No O2 systems for me. My greasy tools serve a purpose preventing rust in the salt environment. I always marveled at the burning of steel wool in a 100% O2 environment. Chemistry class......
