srteach nailed it, PB blaster works good, spray the bolt treads from underneath. now would be a good time to replace any nasty looking bed bolts, head up to ur local boneyard and look at rangers without beds, chances are there ones in better shape, bed bolt and retainers are like 1$ each. just curiours, what contaminated your fuel so bad that the pump is dead? it may be a good idea to add a drainplug to it if you suspect it may happen again.
