i'm installing a greasecar kit on a 2002 f350 superduty and having touble finding the fuel pump relay on the truck. i've consulted the owners manual(which says nothing about it), the instalation guide(which makes no mention of its location) and a haynes manual(which tells its either in the fuse/relay center in the engine compartment or behind the radio in the center of the instrument panel). i've not yet found it but i've yet to pull the radio as well. any advice out there or similar probs?
