use a 20 amp fuse for the fuel pump
If you are going to use the Busa harness ......
I'm going to man up and respectfully disagree with Fred. The Busa fuel pump 12v supply is marginal at best for 15a, let alone 20a. Use a 12v relay, then you don't have to worry.
Though I have no knowledge of anyone having an issue with the stock harness and a higher-draw pump, we ran the fuel pump using a relay, fused on a block running most of the aftermarket electronics.
Lots of good information sharing in this thread!
