I've had this fuchsia bush a couple of years and it's doing very well, but I can't remember if it's an acid loving plant or not.

Actually, yes, these plants do like somewhat acidic soil. Feed with an acid fertilizer, such as those labeled for Azalea/Rhododendron/Camellia plants, using 1/2 to 1/4 recommended strength and dilute it. You can also add coffee grounds to the soil around your fuschia plant. This article will help with that: https://www.gardeningknowhow.com/composting/ingredients/coffee-grounds-gardening.htm
