12v Fuel transfer pump powered from trailer plug?
I will be borrowing a friends fuel transfer pump next week and would like to run it from my 7 pin trailer connection if possible. Not sure of the exact model of pump but I did a search and most seem to be 20A. Would this be feasible? Otherwise I will have to run a cord back from one of the batteries. It would be easier not having to open the hood.

I was hoping someone here had actual experience doing this. Thanks for your reply.

I had to run mine last weekend to take fuel out of my rear tank to replace the fuel pump. I ran it off of the 12v battery charging system on the trailer as the battery was easy to reach in relation to the truck. Ran for a little over an hour, didn't miss a beat. My transfer pump is made from a standard AC Delco 12v fuel pump.

Look here: American Wire Gauge table and AWG Electrical Current Load Limits with skin depth frequencies
Unless your trailer plug has 10gauge wire, I wouldn't try to run a 20A pump on it.
