I doubt it. Nelson and Ray had to put one in to tune it... Maybe just when it is low on gas it does this?

Why in the hell would you change the tank and fuel system on these things. I could see the whole pump upgrade thing but come on..

I don't know if there is an advantage to having 4 less gallons, but he had a pretty nasty motor in it prior to, then put back it the L92.

I think your fuel tank is probably factory, however when the new fuel pump was installed it may have been hung an inch or two higher in the tank. You basically ran out of gas and when you mashed the loud pedal, the remaining gas sloshed to the rear and it leaned out. This caused knock and sensor discrepancies so the truck went to limp mode.
