Re: fuel pump pressure???



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 " .

okay folks,

I have an 88 C-10 305/TBI....when the gas tank gets below 1/4, RPMS drop way down when accelerating from 0 to about 15 or 20....the vehicle has a 34 gal. tank and coolant temps seem to run somewhere between 150-170 ( according to various thermostats that have been tried to get the operating temps up to around 185-190. again.. this only happens when the tank gets below 1/4full.

anybody have a suggestion... by the way.. to my knowledge.. the prom hasn't been screwed around with

thanks in advance
