Hi folks, I'm going to install a Vortech T-Rex 50/70 inline fuel pump and would like to know what amp relay and fuse holder I would need to hook it up with. I've been hearing that a 40 or a 30 amp relay and fuse holder would work. Which amp size would I need to get this accomplished. Thanks for your time and answers towards this request.

 

What is the amp draw of the pump?

 

That's a good question, I'll have to see. Thanks Injuneer.

 

Flow/pressure looks similar to a walbro GSS307 which maxes out at right around 15 amps. I'd run a normal automotive relay and a 20 amp fuse.
