Inboard Tank fuel sending unit gasket replacement G model

[Joes]

I am in the middle of replacing the fuel sending units cork gaskets, how difficult is the removal and installation of the tubular capacitors in the inboard tank? Any help would be appreciated.

Are you referring to the main fuel inter-connects ? Rubber couplers?

Once you remove the bolts from the top of the tanks for the fuel sending units, two wires are attached to a tubular capacitor that sits upright in the tank and measures dielectric values in relationship to the fuel level. That was a mouthful, the tubes are upright in a cradle, just wondering how difficult were they to remove. Can't get the new gasket on without having them out of the tank. Thanks for responding.

They are installed in clips, pull the bottom of the capacitance tube forward towards the front engine and they will pop out of the clips. Make sure on reinstallation that they are oriented correctly, push back in the clips and they will snap in place.

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

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.
