Fix

I also has one on order since late October. When I first mailed them they said thay had 1pcs in stock, but suddenly when I placed my order it was sold... Then promised expected delivery in 2 weeks... Now they just move date forward... and non reply when the might get them in stock.

If some has a spare set of those gauges, I’m interested. M20K 252

Would be happy if we could have an complete guide how to manage engine on the 252 MB/SB Both LOP / ROP

Have you tried to connect 24v to the motor directly and tested it ?

I also have AUX tanks and when I have ~37 gallons in my main tank, around 10 gallons is flowing over to the Aux tank. So my Main Tank fuel meter says roughly 27 gal. In my POH for AUX tanks is says when you measure fuel level. 1/2" = 5 gal 2" = 10 gal 4" = 17 gal

Agree, have it loop pointed towards tail too.

I get different oil level readings depending what way my oil dip stick points. It differs 1qt Not sure why, but that confused me a bit before I always have oil dip stick at same direction now. What is the correct position?

My TSIO-360-SB2 takes around 2-3 days after a flight before I can read the correct oil level. Last Oil/Filter change I filled with 7.5qt, and now it reads little above 6.5qt after some couple of hours of flight.

Anyone that know the difference between 610243-003 vs 610243-001 and 610242-003 vs 610242-001. Is -001 a working substitute for -003 ?!

I found the fuel transmitter behind the lower carpet panel. I could fold the panel gently to access it, it was done previously too... For a swap, I think a full removal of panel and seat is preferred to gain space and better access. I grounded outboard sender, so it's 0 Ohm. With 27 gallon in the tank, fuel gauge is almost full. So either the inboard gauge is more than 30ohm or the fuel gauge is not working as it should. When I grounded inboard sender, fuel gauge went down to zero. I think I've ruled out the fuel gauge as faulty. Will measure Ohm tomorrow on Inboard sender. Will order 2x 30Ohm Potentiometers, then I can quickly test the fuel gauge.

Thanks, will check tomorrow. Are they easy to remove. Do I need to remove seats etc?

Anyone has some good pictures or description how to access the inboard fuel senders? Also anyone that know the difference between 610243-003 vs 610243-001 and 610242-003 vs 610242-001.

Is it possible to access the fuel senders (connection side) from any inspection panel? Or you need to open fuel tank ? My Left Fuel gauge is not working as it should.

Plessy or Eaton spring?

So if I want to order an V-Band Clamp for an TSIO-360SB is it part #653337 if I can find one or is it OK to get the superseded V-Band Clamp #670105 instead? Are both if found "legal" to use, or is there anything I need to check before ordering?
