Hi
Done electrolysis rust removal a few times but it's alot more of a PIA.
I've had good luck with cleaning vinegar from dollar general.
Buy a pack of 1/4" sheet metal screws 10 or so toss them in use a expansion plug for fill hole and cork plugs for petcock holes fill with cleaning vinegar to the top.
Shake shake well you'll have to loosen plug to let air vent out once you set it down takes about a week shaking daily.
Flush out with baking soda and water will flash rust fast after be ready to throw a bottle of light oil like two stroke oil roll around to coat.
Good luck
