    Default Loss of fuel flow

    My problem with a 2002 LB7 with 82000 miles is running out of fuel in the filter during a hard pull with my 9K trailer on a hot day. My wagon just shuts down with no diesel in the filter with no limp and no codes. I was towed to a dealer where they did the flex fuel line replacement to no avail.
    My local GMC diesel master informs me that my problem is that the fuel filter mounting assembly is leaking air when hot and not storing fuel. My cost for replacement is over $600.
    Can anyone add to this as I find no info re: this type of problem on the DP site.

    Thanks for any help
