We use nothing but Holley pumps.Had 3 bad Carter hi buck pumps bad in a rwo.2 BBs 1 SB.Will admit one lasted a week.Put my 30 year old Holley on and it still worked.The one on my 440 has been on 20 years now.My kids 360 has been on the same.Still work great.Remans depends on the reman company.Used quite a few at work and had no problems.Going thru that many pumps something is wrong.Do they just quit leak etc?Rocky
