I had the fuse holder and the plastic of the fuse melted after several years of operation with a Walbro GSS342 authentic 255 liters hour pump. I repaired it by cutting the two wires and put a single large size fuse holder, subsequently I I replaced the pump with an authentic Walbro GSS278 which provides 168 liters per hour and the electricity consumption drops by around 5 amps, the 132 tranny engine on the circuit must be more than 25 liters per km and everything works perfectly well, the mini fuse holder can be a fragile element for high amperage.
