In my 59 Suburban, 16 months ago we replaced the old tired 6 cylinder with a 2004 5.3. I kept the computer and engine pretty much stock. I plumbed a return line from the regulator/fuel filter assembly to the original fuel tank. The fuel pump was installed on the frame rail under the passenger seat. Since then I have put approx 5,000 miles on the truck and my 3rd fuel pump is failing. I'm wondering if the stock pickup tube in the tank is too narrow and causing the pump to always run in a bind. All the rest of the fuel line is the same size of the 2004 lines.
Any ideas would be appreciated.

I would have to say it very well could be the pickup. You really should pull fuel from the bottom of the tank with a sump for the best supply. There is a company called Tanks inc that I use for older swaps they will build the pump into your tank.

What kind of fuel sock are you running on the fuel pickup in the tank?

Are your lines new?
