fuel pump pressure???

[Len Sabatine]

Some vehicles in that year range had fuel tank baffle separation which 
would cause the fuel pump strainer to be uncovered , causing fuel delivery 
problems,
especially @ lower tank volumes. The condition would often lead to a fuel 
pump failure as well , on a longer term basis. Hard acceleration off the 
mark and
it falls on it's face , with the conditions you describe , sounds like a 
ringer. There have been issues with the fuel senders associated with the 
loose baffle as
well. Replaced a tank in the shop with this problem , although , someone 
shouldn't have attempted to raise the truck with floor jack under the fuel 
tank either!
Duh! We see many such problems in the hands of " Kitchen Magicians " .
