Hi All

Couple months back I had my fuel sensor fail on me, really keen to get a new one. Anyone have a lead on one?

While at this post, perhaps worthwhile to give other L29 drivers a heads-up...

Was flying on one of those magic days, lots of puffy cumulous around, bases around 3000ft AGL, tops around 10-15000AGL. Had planned a general aerobatic sortie, but ended up playing in the clouds...dive down to base of little puffy cloud, hard pull to the vertical, fly up the face, roll, pull inverted over the cloud, look for next “target”, aim, pull round the clouds, wow, tunnel ahead, fly through tunnel, aim for next, dead end, penetrate, etc etc. Absolutely awesome flight.

Anyway, sanity prevailed with usual regular system checks, and at some point I was thinking I would have to soon call it a day due to fuel when I realised the gauge seemed more or less the same place as previous check. Still had over enough fuel on the gauge but it did not feel right so throttled right back for best range, aimed straight for homebase, called ATC early asking for priority, then still with +-350l indicated my 200l light came on, and the circuit was busy with aircraft orbiting waiting for entry clearance together with a bunch of aircraft in the circuit. ATC were great though and got me through, long story short, on shutdown at hangar I visually inspected the tank, there was a coupe centimetres of fuel at bottom. She would have flamed out I guess a couple minutes later.

Not good.

So, just a heads up that the gauges can fail, and that despite their reliability one should as always not only keep an eye on qty, but rate of consumption etc.

So, I need a new sender unit, anyone have one for sale?

Interesting.In any case, the best fuel gauge is the clock !

Contact Pete Taylor on the L-29 list. He has the L-29 parts market cornered.
Lost of spare parts and he's very reasonable on price.
Sometimes he will send a part that is very hard to find and then never collect any money for the part.
He's a very good guy!!

And I'm not being sarcastic.

Yes Jean agree. I guess I became too trusting on my L29 over the years. Every time I fill up, I note the quantity indicated in the cockpit before filling up, then check how many litres it takes to fill the tank and the gauge is always very accurate.  And of course when flying you see the gauge moving! I never heard of it getting stuck before.
Out of interest , we removed the sender unit and plugged it back in. The sender works mechanically but sends the wrong electrical signal. Fully extended it shows the tank is full, as you move it the level indicated on the gauge moves down correctly but only to a certain point, at around 350 litres the gauge stops moving.  Further movement does result in the 200litre light on the annunciator coming on.

Yes! It never gets old, I just love it. Also very cool when you inverted over a cloud and see the round rainbow on the cloud from your shadow above / below you.
I tried it in other aerobatic prop planes but its not the same, have to do it in a jet. You need the speed and vertical penetration.  I can only think how great it must be with more performance.
