Need help resolving fuel problem!
2001 C5 LS1: So I just filled up for the first time in this car and noticed the fuel went down quick. At a 1/4 tank the car started to sputter and died as I accelerated. So I filled it up and the car took about 13 gallons and the gauge went to full. I've read a few threads and I'm not too sure were to start. Some say its an issue with the Fuel transfer from the right tank to left tank. What are some ways I can diagnose this problem? I put a can of that Techron fuel treatment in and the car fired up and ran okay, it's full now and I'm going to drive on it to see if it helps but what are some things I can do to fix it? Thanks.

You are on the right track----Could be s sticky or lazy fuel transfer pump-I would fill again when empty and see how many miles you drove and how many gallons it takes to fill up---I think tit holds about 18 gallons when empty---
On next fill up put in a can of "SEAFOAM" fuel treatment---It is the best---Try again--If the same thing happens it's a major job to get the tanks out and install a new pump--
Don't know if there is a fuse or relay for the transfer pump but check that out too

shell V-power fuel along with citgo techron and the fuel gauge is working great and the performance of the vehicle,has also increased. I would like to thank the corvette forum for their words of wisedom. I'm a believer.
