Narrative:

After landing at detroit metropolitan airport, we were cleared to our gate by ground control in our medium large transport aircraft. As we approached the lead-in area for gate, we noticed a fuel supplier company truck parked, unmanned, to the left of the lead-in area. I (first officer) advised the captain that this was too tight to proceed. Our primary marshaller with lighted white wands instructed the captain to continue. A wing walker was put into place in front of the left wingtip. The captain continued slowly at the primary marshaller's direction. I (first officer) did not like this situation at all and kept my eyes on both the primary marshaller and by leaning across the cockpit at the left wingtip wing walker. The wing walker gave the emergency stop cross arm signal to the primary marshaller which I saw, at which time I very strongly said stop the aircraft! The captain applied the brakes and we came to an immediate stop. I told the captain let's secure the engines and have maintenance tow us in, this is too close. The primary marshaller and the wing walker then conferred with each other and elected to have us continue. Again, I did not like this. The captain released the brakes and the primary marshaller gave him a right turn signal. I was watching again, both the wing walker back in place in front of the left wing. He again gave an emergency stop, crossed arm signal, simultaneously, I again said stop the aircraft! And at the same time a shudder was felt by us which turned out to be the left wing contacting the fuel truck.
