Do I need to change the fuel pump fuse to a 15-20 amp for a walbro 255 lph pump?

Just recently, my 10 amp fuse for the fuel pump is blowing out ONLY from time to time? I've checked the wiring and all seems OK.

Are you talking about the fusable link by the battery? Or did you wire the fuel pump yourself? If you ran your own wiring, you should prolly use a 25 or 30 amp fuse, but there should be something in the pump instructs that indicates what fuse to use.

No its the fuse in the fuse box on the driver's side. No I didn't run my own wiring. To make matters worse when I bought the pump it didn't have any instructions with it....crappy!
