I had a capacitive sender in my header tank but could never trust that thing.  I've gone back to a sight gauge.

That’s a great idea, Bruce. Wish I had thought of that while building. I would have put a corning tempered glass “sight glass” as the sight gauge and then covered the whole length of it with a clear vinyl tube clamped on both ends. The fuel would only come in contact with the glass unless that glass broke and if it did that, then the vinyl would hold everything together without a spill until a repair could be made.

Use a larger hose piece that fits over the original fuel hose.  It gives a bigger diameter for the hose clamp to tighten up against and holds the underneath hose better.  You can split the smaller outer hose lengthwise if it won’t quite fit over the inside hose.  Heck you can use two hoses over the inside one if you like!

Re: Today's Progress

Nice work, Mike. I have done the same thing as you with the split vinyl tubing to keep from chopping off parts of my body that I would like to keep. I hung my cone, pointy end up,  from the shop ceiling, then crawled underneath, stood up and did the glassing work “statue of liberty style”. After a while it gets hot, humid and much lower in O2 content. Finally gave up and built my little access port for future repairs. Hang in there you are getting closer.

 

Cheers,

Jay

Hi Corbin,
For what it's worth....
This may not have anything to do with your issue but the photo looks like the (once upon a time) clear plastic tubes supplied with the Quickies. 
Mine would discolor, get soft  at the tank and shrink.  The top, further from the tank, would crack.  Fuel don't actually travel up the tub only the dowel.
After changing several through the years I called McMaster Carr for some guidance.  
When I told the guy that I had been using a clear plastic tubing called Tygothane, I believe, he asked who told me to use that.  I had been getting it from them all these years.  He knew that would not work.  The catalogue even said it was fuel resistant as I remember.  I might add that I couldn't find it in their catalogue this time.
Instead he recommended Pyrex tubing.  You know the glass cookware stuff.  Worried how to cut it to length turned out not to be an issue.  Just scored the tube
with a Dremel cut off wheel until it came apart.  That was just prior to OSH 2019.  It is as clear as a bell and virtually indestructible.  
To cut it I ran it through another plastic tube and squeezed with a vice enough that the Pyrex would turn inside the softer tubing with some resistance so
the Dremel wheel would slowly spin it and make a nice even cut.  That Pyrex glass is very hard so the cutoff wheel was very slow but got the job done and no scratches.
Obviously a lathe would have been better but me don't have one.
Maybe this helps. Keith

I meant only a short piece to go over the aluminum tubing.  About 2” in length.  Sounds like a new idea with the Corning though!

Re: Fuel Sight Tube Broke- pics included

I avoided the entire issue by installing 2 fuel gauges/sending units, one in main and one in header, with low level light annunciator in header tank. It's much cleaner and gets rid of that ugly sight gauge. . Also I run 3/8" fuel line and have no rubber hand fuel pump. Been working fine for 21 years. Just another option.

Honestly, I thought it was discolored by design.  I know some are clear but I thought this was tinted tubing.

Another concern with the sight gauge is not the tube breaking, but the tube slipping off the lower nipple on the tank. This happened to me halfway between Fort Nelson and Watson’s lake and was pretty terrifying! I couldn’t reach the nipple to plug it like I could a broken sight tube. I had just bought the airplane and replaced the tube with new material, but the nipple was a straight tube with no flare, barb, etc. and even with a tight hose clamp the vibration of the instrument panel was enough to work the tube off the nipple. A barbed nipple and restrictor seem like really good ideas when the fuel you need is draining on to your right leg!

Jay,
How do you know if your header tank fuel pump quits and your no longer refilling the header tank?  
Also instead of the 1/4" output on the lines I put in a restrictor.  This way if the line does break, you'd get a much smaller volume of fuel coming out.

Hi Mike,

 

I keep an eye on several things. I have a fuel transfer pump on the main that refills the header. I think that is what you are referring to. When that pump is on, it fills the header much faster than I burn fuel out of the header, so there is a noticeable change in the reading on both tanks. Bad pump would be noticed right away, but I never let the header get below 3 gallons, so I always have at least ½ hour to find an airport….or almost a full hour if I were to really throttle back.

 

Cheers,

Jay

Robin,  
My nylaflow is also 40 years old.  I did find some of the original material in the hangar and it seems to be fine.  I think the stuff goes bad with UV light?  If the plane spends a lot of time outside then I'd replace it.  It looks a bit hard to replace.  I did find this on a manufacturer website... and it's a bit concerning!  Under typical warehouse conditions, Freelin-Wade tubing has a shelf life of 2-5 years depending on temperature, ultra-violet exposure, humidity etc. Under ideal conditions of 75F, 50% relative humidity, and no exposure to UV, the shelf life could be as high as 10 years.
Oh oo,
Mike Dwyer

Lucky break - happening on the ground! Certainly going to be checking mine. The original plastic hydraulic brake lines worry me, too. I have found spare material, that I had left over, to be very brittle too (not surprising after 40 years, I suppose). Anyone have experience of replacing this? How easy/difficult is it?
