Hi Chaps

Apologies for the basic question, are the tubes marked with an up so that it can assist with installation or is it as simple as wires to the top.

Regards
Dave

The orientation of the tubes were with the white plastic insulator on the bottom.

I'm going to pull mine in the next week for a CIES update, I'll take pics if you still need them. They are very easy to remove and generally easy to put back in.

Let me know how that CiES install goes. Mine was a bear and I have a blank spot between 35-50 gal per wing. Talked to CiES at AEA last week and think I can reorient my inboard sender to eliminate the irritating lack of fidelity between 35-50 gals.

‘77 NA G model with long range tanks (150 gal).

Will do! I’m doing my 73G and my brother is doing the family 69D so we will have a few good datapoints.

What is the orientation recommendation from cies?
Can sensors be installed without removing upper wing panels?
This is a near future project for me.

For my 337G i’ll have to pull the wing panels since the access doors aren’t large enough to pass through the large flange. On pre 73 models (verified for 69) the resistive senders are smaller and can be pulled without removing the panels.

As for orientation, tbd.
