Surely this should be done for all power delivery cables if it's done for this particular set?

If it is a European number, I assume the dot is where we use a comma.? In this instance it would be one thousand twenty eight.? If this an American number, it would be one point zero twenty eight; or one and twenty eight thousandths, depending on the context.

The "period" is never used as the 1000's delineator. The "comma" is used for that purpose. Therefore your example cannot be "one thousand twenty eight". The "period" is used as the decimal point in mathematical notation. Numerals after the decimal point are always named individually, never as a group. Therefore 1.028 is "one decimal zero two eight" NEVER "one decimal zero twenty eight". However in literature or in the case you are citing, where the numeral is possibly indicating a paragraph or rule, then a sub-paragraph or sub-rule within that paragraph or rule, normal usage could be to say either "one decimal zero two eight" OR "one point zero two eight" where "point" delineates point number two eight under paragraph number one or sub-rule two eight under rule one, etc. The word "dot" is never used numerically to describe the "period", but is used to describe a period in a web address. For example, "double-you double-you double-you dot aeroelectric dot com" (www.aeroelectric.com) In summary, according to "proper English", as taught in the Canadian school system, your question re; FCL 1.028 would be pronounced in spoken English as "Foxtrot Charlie Lima one decimal zero two eight" OR if quoting a particular rule or paragraph it could be also "Foxtrot Charlie Lima one point zero two eight". If the clarity of the phonetic alphabet is not desired then "Eff, Sea, Elle" could be used for the letters.

No, this suggestion was driven by the fact that when the SD-8 came to the market about 20+ years ago, PLASTIC airplanes with the engine on the wrong end were king. COMPASS interference (due to strong magnetic fields around alternator feeds between the engine on the back and the battery on the front) was eliminated by twisting these wires. Again, this goes to my earlier suggestion that wires should be twisted based on manufacturer's installation instructions . . . and the fact that one system get twisted wires doesn't mean that all systems should get them. A figure Z-13/8 installation on an RV would not benefit from this process.

My best guess is that if your probe has ordinary bundled strands of wire for connection, these wires are NOT part of the capacity dependent fuel sensing system. I would guess that they are power, ground and some signal wire compatible with the companion display. Do you have more than one sensor? Right and left tanks perhaps? Try swapping sensors and see if the problem swaps.
