Just some background. I’m installing a 2005 LQ4 into a 84 Regal. When the fuel pump question came up I read that you needed to use a AC Delco EP241.(S&P website) But I've also heard that this pump will be working itself to death since it was designed to work with TPI & MPI and should only be used in this application. So Ive been looking into alternatives. I have found out that the EP381’s were manufactured with a new thin magnet design which yielded a lot higher torque than that of the EP241’s. They were specifically designed to work on Vortec & LS1 style engines. Also the current draw on the EP380 would be significantly less than the EP241, less current + less heat=longer life. Can I use a EP381 on my sending unit??? I can buy one around here for like $50. Are there other budget alternative fuel pumps out there?

EP241 Flow= 40 gph & PSI = 65-75

EP381 Flow = 50-60 GPH & PSI = 80-90

These pressure readings are right on the head of the pump, Ratings are from airtex.

if you havent already got the answer, yes that pump will work. plugged right into the '87 sending unit in my LQ4 '82 C10
