You can research summit. They have pretty good selection of all types. Look for the handful of in tank aftermarket pumps. No doubt they offer a high volume that will handle a TPI
I run the well known E2000 pump on my TPI rig. It will work in or out of the tank. The nice thing is you can find a dirt cheap backup to throw in the rig as a spare. Head to the junk yard -they are on the frame rail (under driver door) of Ford F150s (85-89 IIRC) I bought the AC Delco branded one. A little more $, but I think its a better made pump. I also have a $10 JY one I ran for 6 months, then retired to spare duty.
