about to install the xs fuel pump part number " SX-18203 Billet 1000hp fuel pump" couple qustions, do i need to get a bigger relay? are the stock relay good enough? if so how big? Also how big should the power wire to the pump be? thanks

 

I used 8 guage wire from alternator with fuse and 30 amp relay. My pump turns on when I turn the key on. This ****** is loud though

 

i think it would be best to pull from the battery or the alternator. all the buicks i built have the power from the alternator.

 

You can use an MSD single pole high amp relay. You can use 10 gauge from the battery with a 30 amp fuse as close to the battery as possible. Then use 10 gauge for the ground from the pump.
