seized bolts

hi
can anyone give me some advise on how to get the bolts connecting my fuel pump to the accumulator off.
ive tried wd40 with no luck. ive also tried getting any of the bolts on the fuel line and accumulator off so i could take the whole system out so i didnt have to work on them under the car. they just wont budge
cheers

try shock and unlock maybe? its a spray you can buy in halfords, near where wd40 is kept, its pretty good, basically freezes the bolt making it shrink a minute amount allowing it to unseize, worth a shot.

cool thanks ill give it a go
