Gas tank on ground... How do I get these @#$& lines disconnected?@

I'm trying to change a fuel pump on a 1991 base model. Tank is unbolted, but I can't get the two lines disconnected to take the pump out. Any suggestions?

If youre talking about the gas lines i think you're talking about you need pliers to hold a nut and a wrenchg to twist the other off, mine was on there pretty tight the one at the fuel rail was on so tight it took off the line

yeah they stick on there really well, some pliers and twisting usually breaks the seal

Thanks! I finally got it with two wrenches, but it was a bitch to fit in there.
