I rip a hole in a bilge absorb pad and poke the pump through the hole; protecting the deck all around the fuel intake. This has helped when the pump is leaky, or delivers too fast, or air bubbles in lines or fuel fills.
Know your boat. Know about how much fuel you need to take on. Listen. Use care.
I have seen the fuel guards used and the absorbent pads work better.
Please don't rinse into our waters; mop up any spills with a rag and dispose properly.
