I have no experience with this stuff, so forgive me but, Why a 30 amp relay and then a 20 amp fuse? As opposed to a 20 amp relay or a 30 amp fuse? Like i said I have no experience with electrical stuff at all. I just figured out how relays work. lol. Thanks.

you use a relay so you dont run to much current trough the ECU. the ecu grounds the relay on the fuel pump when the pump is suppose to run.
a 20 amp fues saves the 30 amp relay
