Decided to fabricate a trim cable guide to assist in containing the tension created on the fuel filter housing by the tight bend in the cable. The plans call for the trim cable to pass through a hole in the forward face of the housing and make a near 180 degree bend to the trim knob. I chose to exist in the tunnel cover (F-783C) and still there's plenty of tension, so I'll add a simple ring retainer near the threaded end to hold it, and a clamp on a custom bracket on the tunnel cover.
