Removing the fuel tank.....

[roamak]

Aryana, I don't know how clean everything looks in your tank bay but I think (without looking at mine own yet) that I would have to agree with n2582d. I cant see myself getting to a point were I can really get a good look into something but really not doing it. Seems like replacing the filler gaskets would be too easy for me and something would happen and a week later I would be tearing it back apart mad as hell I didn't do it right the first time.
Let me know how the cover goes back on. Thanks!

Removing those tanks will also give you the opportunity to replace those 50+ year old hoses on the vent line, if you haven't already done so. Good luck.

If an inspection reveals that the vent hoses are old and need replacing, don't forget that there two hoses on that vent line at the base of the gooseneck up under the headliner in the center of the cockpit. I sure as hell forgot them until I had the exciting experience of a dripping fuel leak and fuel soaked headliner on a flight into Johnson Creek,ID,when I dumped the nose for a rapid letdown into the canyon with full tanks. Boy, let me tell you that will really tighten up the old drawstring.
When you dump the nose with full tanks, that cross cabin vent line will flood with liquid fuel.

Which placard would you use? 100LL only, since 80 isn't available anymore? Or does the 80/100 placard make sense since 80 is the min required for the engine. I previously had the 80/100 around the filler necks but those were put on 20 years ago....

Fuel placards (in fact, any tank or container on an airplane) should indicate:
TYPE/GRADE/QUANTITY. Such as "Fuel" or "AvGAS" or "AVGAS/GASOLINE" per "ASTM yadayadayada". "21 U.S. gals."
Those placards do not meet the complete rule.

"Hydraulic Fluid, Mil-5606, 2.4 U.S.Gal." "Engine Oil, SAE 50, 8 qts." "Engine Oil, MIL-L-6082E, 2 U.S. gallons" "Oxygen, Liquid Breathing, 18 L."etc etc

Does anyone have a source for placards that meet the rule?

Cessna Airplane Co. or the holder of whatever STC to which your airplane is subject. Spruce also sells a few.

My own is custom-painted at the filler.

I might be late to the conversation but why bother with a placard?

[canav8]

Required placards are usually on the last page of the TCDS. Doug

Steve, the FAA could ground your aircraft on a ramp inspection. All TCDS info is at finger tips of the FAA with a smart phone. Caveat Emptor.

With a flare tool and tubing bender, you can make the line yourself (A&P)

Buy twice as much line as you think you'll need and practice bending the right lengths.
It's not hard to do.

Aryana, take a look at the IPC page 104 (figure 63) it the vent system however it does not show the fitting in your picture either.

[bagarre]

That's a photo of the fuel delivery system, the fitting to the tank or about #10 in your diagram.

It looks a lot closer to item 2 and 2A in the fuel system diagram.

[bagarre]

I'm not sure of the exact part number, I was just referring to what looked close in that diagram. I think the diagram was pointing to the union and not the fuel line.

We used clear vinyl tubing for chafe when we made mine.
There probably is a burn requirement for it tho.
An old piece of fuel line would also work.

• CAR 3:
  § 3.767 Fuel, oil, and coolant filler
  openings. The following information shall be
  marked on or adjacent to the filler cover in each
  case:
  (a) The word "fuel," the minimum
  permissible fuel octane number for the engines
  installed, and the usable fuel tank capacity. (See
  § 3.437.)

• Sec. 23.1557
  Miscellaneous markings and placards.
  
  (c) Fuel and oil filler openings. The following apply:
  [(1) Fuel filler openings must be marked at or near the filler cover with--
  (i) For reciprocating engine-powered airplanes--
  (A) The word "Avgas"; and
  (B) The minimum fuel grade.

[/list]

Since our aircraft are certified under CAR 3 we use CAR 3.767 and any placards called for in the TCDS or that have been mandated through an AD. I've not researched ADs.
