Changed fuel filter after initial flush of fuel distributor with high concentration of injector cleaner.......so on second filter since getting it restarted

New filter may still have clogged up quickly........but at 40 Aussie dollars each I will check delivery rate cold and when playing up first.....any other tests to pin-point fuel filter as culprit ?

Fuel strainer in tank also sounds worth checking.......tank full at present just to make things difficult !

Will try removing fuel cap when starts to play up to see if 'big suck in' & any improvement........not sure how my tank is set up, but probably similar to 1978 California models

My wife has suggesting adding a cell phone and Autoclub Card to the Tune-up Kit....no faith !!

Keep the ideas coming please....I appreciate everyone's input
