It’s months since I last did an up-date but in fairness, months since I had any truck time. Finally got back to it last week and finished the fuel tank install which included fitting a 0-30-ohm sender which appears to work fine with the gauge in the dash.
For the fuel line I’ve used 3/8 aluminium hard-line which is fine but like copper will work harden and could crack if not securely clipped to the chassis.
I used these plastic clips, they’re a push fit with a cover that clips over the top making them double secure.
I used AN-6 fittings and stainless braided hose to connect the tank to the hard-line
