2002 Suburban Flex Fuel Pump
 
Hi guys. I have a question that maybe someone here will know the answer for. My 2002 Suburban 1500 LT flex fuel with the 5.3L has the typical check valve issue in the fuel pump. It works fine once you get it to fire, but normally you have to cycle the key a few times to get the system up the pressure before it will start.
Anyway, I ordered a pump (just the pump, not the basket) off of Ebay. It was a genuine AC Delco pump that was supposed to the be correct one, which of course, it wasn't. My question is, does anyone know of a pump that will go in this basket? I have replaced the before in other vehicles, but being flex fuel, it seems to be harder to come up with. I did get a part number off of the pump while I had the basket out, but a Google search doesn't come up with any matches. 3391 3101 1280 were the numbers inscribed in the pump. There didn't seen to be any other numbers. Any ideas?

why don't you get an external check valve and install it in the fuel line near the tank.
