My fuel tank needs to be replaced I think! The baffle inside it has come loose and blockes the fuel pump on hills and will not let it get enough fuel! Is there any fix for that or just get a new tank?? Question (2) if I need a new tank any input on plastic or steel JC Whitney has them for 170 steel 200 plastic Which on would be best?? Its An 89 k5 350 FI 4x4 w/31 gal tank. Thanks for any help!! IF IT'S NOT AS BIG AS YOU ARE DRIVE OVER IT!!!!!!!!!!
