Relay for electric fuel pump

I just installed a 502 so I need to run an electric fuel pump. What relay are you guys using?

I use a dirt simple four pin 40 amp relay for $5 at Autozone.

This 30 amp is the only one they're listing. 30 amp should be plenty, right?

Advance is closer and they have this one. What do you think?

I just pull the center wire out since you won't need it with most applications.

Thanks!

I'm going to Advance during lunch and pickup a relay and hope they have the pigtail. If not I'll just wire it up without it. At this point the relay is the only thing keeping me from starting the new engine.
